【自然派「バイオトイレ」 旭川2022家づくり探訪-8】




きのうの続きで旭川・芦野組施工のエコ志向住宅です。
建物の外壁１面ではワラによる断熱層が作られ、塗り壁仕上げされている。
アメリカなどではストローベイルハウスというワラ束による家づくりもある。
非定常的な自然素材であるワラは、定性的な「性能検証」が難しい。
その機能性を検証できるグラスウールはその開発発想に於いて
人類的知見であった繊維状素材の「静止空気」保存性能に着目して
排ガラスを工業的に再生利用した叡智。しかしそのマザーであるワラ束には
定性的性能評価は非常に困難、ということはわかる。不定型な自然が相手。
ただ、住宅研究者に日本での断熱材素材の歴史のご意見をうかがうと
「日本ではストローベイル断熱というのはありません。
断熱と言えば鋸くず、カンナ屑、稲わら系もありますが「茎部分のワラ」ではなく、
「もみ殻」を利用しているのが相場。壁の中に充填するには、
もみ殻のほうがすき間なく施工できて扱いやすいからなのでしょうけど、
ワラを断熱用途として使おうという発想がすくないのは不思議。」とのこと。
ワラの利用というのは欧米的着眼・発想であるのかも知れません。
このあたりは人類的DNAの明確な「相違」であるのかもしれない。
アフリカを出て、中東地域で東西に分かれたという人類史で
不可思議な「分化」が生まれたモノでしょうか、あるいは
その後の地球寒冷化で様相がアジア大陸とヨーロッパ地域で違ったのか。
非常に興味を惹かれる次第であります。

さて上の写真はこの家の２階のトイレであります。
「？」というのが第１印象。わたしはキャンプなどの趣味はないので、
このバイオトイレをはじめて見た。それも一般住宅の設備として・・・。
バイオトイレは水を使わず排泄物を微生物の力で分解・処理。
水洗トイレの概念とは全く異なるトイレのこと。
住宅設備としてまったく初見だったので多くの見学参加者も興味津々。
「分解された排泄物の中には様々な有機物が含まれているため、全ての成分が
水と二酸化炭素になるわけではありません。窒素やリン、カリウムなどは分解されず、
木質チップに残っており時間が経つとたい肥となる。
微生物の力を使って水を一切使わずにトイレを利用することができる」という考え。
最近自然派志向のグッズとして注目されているようで
多くの企業が製品開発してきているので検索ください。参照URL。
サクラの棒が添付されているけれど、これは便層内を撹拌して微生物分解を
促進させるためのものだそうです。

また、建物内の換気についても２階寝室に大風量の排気装置があり、
毎日一定時間、人感的に定時動作させることで必要換気量を確保する考え。
計画的機械換気というのが一般的趨勢ですが、そういう機械依存的ではない
考え方というのも、目からウロコと思われました。

Asahikawa 2022 House Building Exploration-8
Instead of flushing, excrement is decomposed and treated by the power of microorganisms. The camping boom has led to a gradual increase in the number of manufacturers entering the market. …

Continuing from yesterday, this is an eco oriented house constructed by Ashino Gumi in Asahikawa, Japan.
On one exterior wall, a straw insulation layer has been created and the walls are painted.
In the U.S. and other countries, strawbale houses are built using straw bundles.
Straw is a non-routine natural material, making it difficult to qualitatively verify its performance.
Glass wool, whose functionality can be verified, was developed based on the human knowledge of fiberglass.
Focusing on the “still air” preservation performance of fibrous materials, which had been known to mankind
The wisdom of industrial recycling of waste glass. However, it is very difficult to qualitatively evaluate the performance of its mother material, straw bundles.
I understand that qualitative performance evaluation is very difficult. We are dealing with an indefinite nature.
However, when we asked a housing researcher for his opinion on the history of insulation materials in Japan, he replied
In Japan, there is no such thing as strawbale insulation,” he said.
When it comes to thermal insulation, there are sawdust, wood shavings, and rice straw, but it is not “stem straw” but “rice husk” that is used in the market.
The most common use of strawbale insulation is rice husks. To fill in the walls, it is better to use rice husks.
I guess it is because rice husks are easier to handle and can be used to fill walls without gaps.
It is a wonder that there are so few people who have the idea of using straw for insulation. It is strange that straw has not been used for heat insulation.
The use of straw may be a Western concept.
This may be a clear “difference” in human DNA.
In the history of mankind, we left Africa and divided into East and West in the Middle East region.
Or perhaps a mysterious “differentiation” was born in the history of mankind when we left Africa and divided into East and West in the Middle East region.
or perhaps the subsequent global cooling caused a difference between the Asian continent and the European region?
I am very much interested in this.

The photo above is a bathroom on the second floor of this house.
My first impression was, “What? was my first impression. I am not into camping, so this is the first time I have seen this bio-toilet.
I have never seen this bio-toilet before. I had never seen a bio-toilet before, and it was installed in an ordinary house.
The bio-toilet uses microorganisms to decompose and dispose of excrement without the use of water.
It is completely different from the concept of flush toilets.

Many of the tour participants were very interested in the system, as it was completely new to them as a housing facility.
The decomposed excrement contains a variety of organic matter, so not all of the components can be turned into water and carbon dioxide.
Not all of the components become water and carbon dioxide. Nitrogen, phosphorus, potassium, etc. are not decomposed and remain in the wood chips.
remain in the wood chips and become compost over time.
The idea is that “toilets can be used without using any water at all by using the power of microorganisms.
It seems to be attracting attention as a nature-oriented product these days, and many companies are developing products.
Many companies have been developing products, so please search for them.
The cherry stick is attached to the product, but it is supposed to agitate the stool layer to promote microbial decomposition.
This is said to agitate the inside of the stool bed to accelerate microbial decomposition.
Also, regarding ventilation in the building, there is a large airflow exhaust system in a bedroom on the second floor.
The idea is to secure the necessary ventilation volume by operating it manually at regular intervals every day.
While the general trend is to use planned mechanical ventilation, this kind of non-machine-dependent approach was also an eye-opening experience for me.
This is the trend of planned mechanical ventilation, but the idea of not relying on such mechanical ventilation was also an eye-opener for us.
＜This report will be continued tomorrow. ＞

【自然派志向の木外壁・ワラ断熱・・・ 旭川2022家づくり探訪-7】




旭川住宅見学記その４、芦野組さんの現場。
長く旭川の新住協活動の中心的存在として活躍の作り手。
高断熱高気密技術とともに個性派建築家とのコラボも多く、
個性派志向の建て主さんからの「指名」も多い。
今回見学の住宅もかなり個性派で、会員企業間での話題も大きかった。

敷地は東旭川の自然、苑池に面している好立地環境。
室内から常にこの湖面を眺めて暮らせるという垂涎の環境です。
やや黒っぽい外観で「なかなかに、っぽいなぁ」と近づいていって
外壁素材が非定型的な形状であることに目が慣れてくる。
「この家の素材はほぼ施主さんからの支給品が多いです」
というコメントが得られました。
芦野組さん自体、自然素材系で建築する住宅が多いのですが、
類は友を呼ぶということか、同じ志向性の建て主さんということ。
木質外皮は規格的に整形せずに「あるがまま」の湾曲ぶり。
まぁ基本的に断熱層・通気層は外壁手前側で成立させているので
外壁材自体は、どのような素材であっても自由度は高くなってくるといえる。
わが家なども外断熱なので木質＋角波鉄板＋煉瓦積みなどと
自由な素材選択・組み合わせで構成してもらった経験があるので
理解はできるけれど、施工上は規格寸法のほうが合理的に成立させやすい。
この建物では軸間に105mm＋付加断熱GW210mmの300mm断熱層。
外壁材を保持させる下地は縦に胴縁45mmが入っているので
鉛直方向での「不揃い」はクリアできるとは思われる。
下見板張りを工法採用しているので、材の不揃いぶりは重ね部分の
工夫で現場対応ということなのでしょう。
外壁材の樹種は北海道産の「トドマツ」木酢塗りで木口部分は
その木の外皮部分がそのまま露出していると見受けられました。
樹皮自体は剥ぎ取られた素材のようです。
見た感じでは長さは一定寸法に収まっていたように思います。
しかし、大工造作は１枚一枚、慎重な作業だったことでしょう。


さらに驚かされたのが、上の写真の正面側の壁であります。
外壁素材はまぁこだわりだなぁ、ということでしたが、
こちらの１面の壁はなんと「ワラ素材＋土塗り壁」で仕上げられている！
え、と思わず問い返したのですが、充填＋付加断熱はワラ断熱500mmとのこと。
建て主さんは自然派木こりとして知られる陣内雄さんの家づくりサークル会員。
〜陣内雄、北海道出身のキコリ・シンガー。歯笛プレイヤー。
葉加瀬太郎と音楽友達。東京芸大・建築科出身。〜
Replanでも以前、ワラの家を誌面で紹介していましたが、
わたし自身は一般住宅の実作で見るのは初めてでした。
通常のGW断熱層との連続性確保は責任施工範囲でクリアさせている。
この外壁施工時にはサークル会員さんが集まって作業したとのこと。
・・・さすが旭川、こだわりもディープです。

Asahikawa 2022 House Building Visit-7
The exterior walls are made of uneven, natural Abies sachalinensis, and one wall is finished with clay and 500mm of straw insulation. The house is bursting with attention to detail. …

Asahikawa housing tour No.4, Ashinogumi’s site.
Ashino Gumi has long been a central player in Asahikawa’s Shinjyukyo activities.
They have been collaborating with many unique architects as well as using high heat insulation and airtight technology.
The houses we visited this time are also quite individualistic.
The house we visited this time was also quite unique, and was the topic of much conversation among the member companies.

The site is favorably located facing the natural beauty of Higashi-Asahikawa, En-ike Pond.
It is a coveted environment where one can live with a constant view of this lake from indoors.
The somewhat black exterior of the building made me think, “It’s quite, like…” as I approached it.
Your eyes become accustomed to the atypical shape of the exterior wall material.
The materials in this house are almost exclusively supplied by the client.”
I got the comment, “I’m not sure.
Ashino Gumi itself builds many houses with natural materials.
It seems that the same kind of people build houses with the same orientation.
The wooden exterior skin is not shaped in a standardized way, but is curved “as it is.
Basically, the insulation and ventilation layers are formed on the front side of the exterior walls.
The exterior wall material itself can be made of any material with a high degree of freedom.
Our house is also externally insulated, so it can be made of wood + corrugated iron sheets + brickwork, etc.
I have experience in having my house constructed with a free choice and combination of materials, so I can understand.
I can understand this, but in terms of construction, standardized dimensions are more reasonable.
In this building, there is a 300mm insulation layer of 105mm between the shafts + 210mm of additional insulation GW.
The substrate that holds the exterior wall material has 45mm of furring strips vertically.
It is thought that “unevenness” in the vertical direction can be cleared.
Since clapboarding is used in the construction method, the unevenness of the material is
The clapboards are made of Hokkaido wood.
The exterior wall material is Abies sachalinensis from Hokkaido, and the wood is coated with vinegar.
The bark itself seems to have been removed.
The bark itself seems to be a stripped material.
The length of the tree seemed to be within a certain dimension.
However, the carpentry work must have been very careful, piece by piece.

Even more surprising was the wall on the front side of the photo above.
The exterior wall material was, well, a matter of taste.
This one wall here is finished with “straw material + clay painted wall”!
I asked him what he meant, but he told me that the filling + additional insulation is 500mm of straw insulation.
The owner of the house is a member of the house-building circle of Yu Jinnai, a well-known natural lumberjack.
~Osamu Jinnai, Kikori singer from Hokkaido, Japan. Tooth flute player.
Music friend of Taro Hakase. Graduated from Tokyo National University of Fine Arts and Music, majoring in architecture. ~Replan
Replan had previously featured a house made of straw in its magazine, but this was the first time for me to see a real house myself.
This was the first time for me to see an actual house.
The continuity with the normal GW insulation layer was cleared within the scope of responsible construction.
The members of the circle got together and worked on this exterior wall construction.
……As expected of Asahikawa, the attention to detail is also deep.

【寒冷地住宅のエネルギー選択 旭川2022家づくり探訪-6】





写真は北海道ハウジングさんの旭川近郊・東川の施工現場。
工事途中の現場見学ということで、室内の気密施工と換気の状況。
北海道ではこのような基盤技術的な共通仕様が固まっていて、
選択要素である断熱厚みについては柔軟な対応ができる。
防湿シートの安定的な施工技術があればあとは断熱レベルはコスト次第。
そしてそれはコストを含めたエネルギー選択の問題。・・・

先日、アメリカでも脱炭素の先端地域と言われるカリフォルニアで
この夏の猛暑、連日40度を超える状況の中で
「電気自動車（EV）への充電は避けるように」という注意報が発出された。
アメリカではバイデン政権は国内の石油資源利用について
非常に抑制的な政策で、結果シェールガス生産が抑制されている。
そのタイミングでロシアのウクライナ侵攻で世界的エネルギー危機。
バイデン政権は自国ではSDGs政策を進めているが
世界の資本主義の盟主としてはエネルギー価格高騰は防ぎたいという
政策的ジレンマの中に置かれている。
感染症への対応で積極財政政策を取っていることも重なって
物価高騰レベルがハンパなく、中間選挙で現政権はキビシイ状況。
エネルギー戦略の舵取りというのは非常に難しい。
エネルギー選択では徐々に自然エネルギー依存が強まっているけれど、
生活インフラがクルマEV化に舵を切っていくなかでアメリカ国民に
「電気自動車（EV）への充電は避けるように」
ということでは将来的にも暮らし方自体、非常にキビシイ。
ヨーロッパでも問題は同様で、世界の未来対応は非常にセンシティブ。

この問題は世界共通であり北海道の暮らしに直結するテーマ。
エネルギーについては世の動きに対応して行くしかないと思うけれど
住宅建築では建て主の未来の生活基盤に係わってくる問題であり
無自覚にはいられない。選択はしていかなければならない。
北海道の広大な自然環境の良さを暮らしのメリットと感じるためには
やはりクルマの利便性への依存は避けられない。そのエネルギー基盤として
自家消費としての太陽光発電は合理的だけれど、
北海道の日本海側・北部では冬の多雪時期に稼働率が大幅に下がったり、
あるいは一時的に「途絶」するのでは生活インフラたり得ない。
「きょうは大雪でお日様も隠れているので、暮らしもお休み」
と言うワケにはいかない。命にすら関わる。
感染症とウクライナの情勢は、建築にも資材高騰に結果しているが
いまの時代は長いスパンでの選択には難しい時代なのだと思わされる。
必ずしも平和な環境とばかり見通しにくい未来展望の中で
わが家のエネルギー将来像をどう描いたらいいのか、
ひとりひとりに選択を突き付けられてもいると思う次第。

Energy Choices for Cold Weather Homes Asahikawa2022Home Building Exploration-6
A “avoid electric vehicle (EV) charging” warning was issued in California this summer. Energy choices for living are not waiting. …

The photo shows Hokkaido Housing’s construction site in Higashikawa, near Asahikawa.
This is an onsite visit during construction, and shows the airtight construction and ventilation of the interior.
In Hokkaido, common specifications for basic technology like this have been established.
The insulation thickness, which is a factor of choice, can be flexibly adjusted.
Once a stable construction technique for moisture-proof sheets is in place, the insulation level depends on the cost.
And it is a matter of energy selection, including cost. ・・・・.

I was recently in California, one of the leading decarbonized regions in the United States.
In the midst of this summer’s heat wave, with temperatures exceeding 40 degrees Celsius every day
A warning was issued to avoid charging electric vehicles (EVs).
In the U.S., the Biden administration has been very restrained in its use of domestic petroleum resources.
The Biden administration has been very restrained in its use of domestic oil resources, and as a result, shale gas production has been curbed.
At the same time, Russia invaded Ukraine, causing a global energy crisis.
The Biden administration is pursuing SDGs policies at home, but
But as the world’s capitalist ally, it wants to prevent energy prices from skyrocketing.
The Biden administration is caught in a policy dilemma.
Combined with its aggressive fiscal policy in response to infectious diseases
The current administration is in a difficult situation due to the mid-term elections, as the level of price hikes has been unacceptable.
The energy strategy is very difficult to steer.
Although energy choices are gradually becoming more and more dependent on renewable energy sources, the infrastructure for daily life is shifting to EVs for cars.
As the infrastructure for daily life is shifting toward EVs, the American people are being asked to “recharge their batteries for electric vehicles (EVs)” and to “take advantage of the new energy sources.
“Avoid charging electric vehicles (EVs).
This is a very difficult situation for the future of our way of life.
The problem is the same in Europe, and the world’s response to the future is extremely sensitive.

This issue is universal and directly related to the way of life in Hokkaido.
As for energy, I think we have no choice but to respond to the world’s trends.
However, in the case of residential construction, it is an issue that will affect the future infrastructure of the owner’s life.
We cannot be unaware of it. We must make choices.
In order to feel the benefits of Hokkaido’s vast natural environment
we must depend on the convenience of the car as the energy base. As an energy infrastructure, solar power generation for private consumption is a rational choice.
Solar power generation for private consumption is reasonable.
However, in the Sea of Japan side and the northern part of Hokkaido, the operation rate drops drastically during the heavy snowfall in winter, or is temporarily “interrupted”.
However, if the operation rate drops drastically or is temporarily interrupted during the heavy snowfall in winter in the Sea of Japan side and northern part of Hokkaido, it cannot be considered as a living infrastructure.
It is not enough to say, “Today is a heavy snowfall and the sun is hiding from us, so our daily life is closed.
It is not enough to say, “Today is a heavy snow day and the sun is hiding from us, so our lives are on the line. It is even life-threatening.
Infectious diseases and the situation in Ukraine have resulted in a sharp rise in the cost of materials for construction.
The current situation makes us think that it is difficult to make choices in the long run.
In a future that is not necessarily peaceful, how do we envision the energy future for our homes?
How should we envision our family’s energy future?
I believe that each and every one of us is faced with a choice.

【構造と断熱気密・白熱論議 旭川2022家づくり探訪-5】





旭川のイマドキ住宅見学、その３軒目は北海道ハウジングさんの構造現場。
北海道の住宅性能的現在地点はいま、北海道庁建築指導課を中心にして
いわゆるZEHの論議からスタートし、その先の2030年、2050年の
世界的な目標基準をどのように地域としてテーマ目標を定めるか、
活発な論議が進行しています。
審議会は国の住宅施策検討の中心メンバーでもある鈴木大隆さんが
本来の道総研理事としての立場から「座長」として主導。
わたしもその論議には参加させていただいています。
今2022年期の集中的論議ではすでに３回ものワーキング会合を開催。
鈴木座長としては「これまでの住宅施策についての北海道の先導的立場を
しっかりとわきまえながら、先人の思いを継承していきたい」という意見。
折に触れてそうしたテーマ意識が表出されて
研究開発主体の北総研をしっかり領導する論議が展開しています。
この10月には国の「住宅月間」中央イベントが札幌開催。
そのタイミングでこの論議の中間結果が発出されていく可能性もあります。

旭川の工務店グループは住宅性能開発では北海道内でも最先端。
本部が旭川にある北総研の研究開発の技術的パートナーとして経験蓄積。
日本でいちばん寒くて、雪も多いという地域特性から
実証検証を研究者と産学協働してきた歴史があります。
新住協活動でも、鎌田紀彦先生とともに最先端技術開発に取り組んできた。
そういう地域です。しかし一方東京都が象徴的ですが
ZEHの最大要素素材である太陽光発電では冬の多雪条件から
屋根面での搭載は非常に困難を伴う地域的ハンディを負っている。
積雪による稼動ロスを「壁面設置」などでクリアするとか、
さまざまな実証検証に踏まえた手法開発が続いてきている。
さらに広い北海道では多様な気候環境に細分化されてもいる。
そういう論議を経て、2050年も見据えた方向性が確定してきている。
北海道住宅局建築指導課からの情報発出を待って
大いに情報発信していきたいと考えています。

この住宅は昨日までご紹介の家と同じ東川の高台の家。
こちらでは木々が伐採された環境になっています。
敷地は広大なので雪は落雪屋根としていますが冬季の利便性を考えて
駐車スペースは屋内に設定している。
3番目の写真がその屋根架構の様子です。
積雪対応をしなければいけないが、カーポートなので柱の類は
必要最小限化する必要があるため、梁組・小屋組はまことに重厚な構造。
積雪対応という意味で構造面でもハンディキャップはある。
まさに「課題の最先端地域」北海道でも最たる地域性。
しかしそういう住宅性能実験地域でもあることで、
作り手たちの先取精神は高いレベル。
どうやったら構造の強化とコストのバランスを取れるのか、
実務家たちの実践的な白熱した論議が交わされていました。

Structure, Insulation, Airtightness, and Heated Discussion: Asahikawa 2022 House Building Visit-5
Hokkaido, a region at the forefront of the issue, is formulating a policy in response to the national declaration on decarbonization and will issue measures for the year 2050. Asahikawa 2022 House Building

The third house on our tour of Asahikawa’s “Imadoki” houses is the structural site of Hokkaido Housing.
The current state of housing performance in Hokkaido is now being discussed by the Building Guidance Division of the Hokkaido Government.
The current state of housing performance in Hokkaido starts with the discussion of the so-called ZEH, and how to set global target standards for the years 2030 and 2050.
How can we set a theme target as a region for the global target standard in 2030 and 2050?
Active discussions are underway.
Mr. Hirotaka Suzuki, who is also a core member of the national government’s housing policy review committee, has been a member of the council.
I also took part in the discussion.
I have also participated in the discussions.
Three working sessions have already been held in the intensive discussions for the current fiscal year 2022.
As Chairperson Suzuki says, “While keeping in mind Hokkaido’s leading position in housing policies to date
We would like to inherit the thoughts of our predecessors while keeping in mind Hokkaido’s leading position on housing policies.
He expressed his awareness of this theme from time to time.
Discussions are being held to firmly lead the North Research Institute, which is the main research and development institute.
This October, the central event of the national “Housing Month” will be held in Sapporo.
It is possible that the interim results of this discussion will be issued at that time.

Asahikawa’s construction group is at the forefront of housing performance development in Hokkaido.
The group has accumulated experience as a technical partner in the research and development of the North Research Institute, which is headquartered in Asahikawa.
The region is the coldest and snowiest in Japan.
We have a long history of collaboration with researchers and industry-academia for verification and validation.
In the Shinjyukyo activities, we have been working with Dr. Norihiko Kamata to develop cutting-edge technologies.
This is the kind of region we have. On the other hand, Tokyo is a symbolic example.
However, as Tokyo is symbolic of, solar power generation, which is the most important element of ZEH, is very difficult to install on roofs due to the heavy snowfall in winter.
The roof surface of solar power generation, which is the most important element of ZEH, is at a disadvantage in the region due to heavy snowfall in winter.
The operational loss caused by snow accumulation can be cleared by “wall mounting” and so on.
The development of new methods has continued based on a variety of demonstrations and verifications.
Furthermore, Hokkaido, a large island in Japan, is subdivided into a variety of climatic environments.
Through these discussions, the direction of the project is being finalized with an eye toward 2050.
We are waiting for the Building Guidance Division of the Hokkaido Housing Bureau to issue information.
We hope to provide a great deal of information on this project.

This house is located on a hill in Higashikawa, the same house we introduced yesterday.
Here, the trees have been cleared and the environment has been cleared.
The site is vast, so the snow is set to fall off the roof, but for winter convenience
The parking space is set indoors.
The third photo shows its roof structure.
The third photo shows the roof structure, which must be able to cope with snow accumulation.
The beam and shed frames are very massive in order to minimize the need for columns.
In terms of snow accumulation, the structure is also at a disadvantage.
This is the most advanced region in Hokkaido, which is truly a “cutting-edge region in terms of issues.
However, the fact that this is also a region that experiments with housing performance has made it a place where the spirit of forward-thinking builders is high.
The creators have a high level of forward-thinking spirit.
How can we balance structural reinforcement and cost?
Practitioners engaged in heated discussions on how to balance structural reinforcement and cost.

【家具と家づくりのフュージョン 旭川2022家づくり探訪-4】




アース21旭川例会住宅見学、２軒目は北の住まい設計社さん。
こちらは家具のブランドメーカーで全国に幅広く展開しています。
その流れで家づくりにも参入したという変わり種企業。
ただ、社名からは家具作りを通じて家の空間すべてに関わる志向性は感じる。
わたし自身は家具メーカーとしての取材経験もあり、
その後住宅を手掛けられ、またさらに最先端の家づくり研鑽グループ
アース21にも参加したということで、強い意気込みを感じていた。
家具作り同様、細部までしっかりしたディテールを追求されて
「長く使える空間」を志向されている様子は伝わってくる。
家具に使う材への吟味は建築へのそれと比べて、より深くなる。
素材へのこだわりを語られるときの情熱には動かされるモノがあった。
たぶんそのあたりでの心理は表現を超える部分もあると思います。
そういうことなので、建築の空間づくりに於いても目指す「佇まい」が
より濃密で、深くなっていると思えます。
なんというか、空間の手づくり感が伝わってくる。
そういった空間の密度の深さみたいな部分を今回外部アプローチで感じた。



自然の豊かな環境そのまま、周囲には樹木があるけれど、
そこから家にたどりつくエントランスには砂利〜札幌軟石敷き込み。
ふと気になって砂利の深さを尋ねたら20cmなのだという。
そしてその上に重ねられた札幌軟石はぴったりと整合している。
この家は建てて数年経過、幾つかの冬を超えている。
まるでモルタルででも下部が固められているように思えた。
しかし、天圧を掛けた砂利20cmの上に「置いている」だけだという。
ご存知のように北海道は「凍結深度」という概念があって、
家の基礎は深く掘り下げることが義務づけられている。
冬期間の寒冷で表面土壌中の水分が凍結し地面が凸凹になるので、
その対応策として家の基礎については深く掘り下げるのが基準になっている。
ちなみに東川では80cmと定められている。
その上に建つ住宅への被害を防止する工法基準。
ただ、それ以外の外周部には当然、基準があるワケではないが、
この外部アプローチでは20cm掘り下げでこの写真のようにしっかり固定されている。

そして最後の写真はその札幌軟石から玄関に入っての床のタイルの様子。
ずっと「足下ばかり見て」きたけれど、その素材選択の感覚に
なにか強く惹かれていたのであります。
石のデザイン、っていうようなハーモニーを感じていた。

Fusion of Furniture and House Building Asahikawa 2022 House Building Exploration-4
Furniture making and house building, and the dense relationship between them and human beings. The attitude of craftsmanship felt in the exterior approach molding. The exterior approach molding.

The second house of the Earth 21 Asahikawa meeting house tour was by Kita no Sumai Sekkeisha.
This company is a furniture brand manufacturer with a wide range of operations throughout Japan.
This is an unusual company that has entered the home building business as part of the same trend.
However, from the company name, I sense that they are oriented toward all aspects of home space through furniture making.
I myself have experience in reporting on furniture manufacturers.
I have also worked as a furniture maker, and later on as a house builder.
I was also impressed by his strong enthusiasm for the project, as he has participated in Earth 21, a cutting-edge house building study group.
As with furniture making, he pursues the details of the house with a strong sense of detail.
The client’s desire to create a “space that can be used for a long time” is evident in their work.
The materials used for furniture are more carefully examined than those used for architecture.
I was moved by his passion when he talked about his commitment to materials.
Perhaps there is more to the psychology in this area than expression.
That is why the “appearance” that we aim for in architectural space creation is becoming more dense and deep.
I think that the “appearance” that we aim for in architectural space creation is becoming more dense and deep.
I can feel the handmade feeling of the space.
I felt that kind of depth of spatial density in the external approach this time.

The house is located in a rich natural environment with trees around the house.
The entrance to the house is covered with gravel and Sapporo soft stone.
I was curious about the depth of the gravel, and was told that it was 20 cm.
The gravel was 20 cm deep, and the piled stones were perfectly matched to the gravel.
The house has been built for several years and has been through several winters.
It seemed as if the lower part of the house had been hardened with mortar.
However, the house was only “placed” on 20 cm of gravel with top pressure applied.
As you know, Hokkaido has a concept of “freezing depth.
The foundation of a house is obliged to be dug down deeply.
The cold winter temperatures cause the water in the soil to freeze and the ground to become uneven.
As a countermeasure, it is standard to dig deeper for the foundation of a house.
In the Dongcheon River, the standard is 80 cm.
This is a construction standard to prevent damage to houses built on top of the foundation.
However, there is no standard for the rest of the perimeter.
In this case, the exterior approach is fixed firmly in place by digging down 20 cm, as shown in this photo.

The last photo shows the floor tiles from the Sapporo soft stone to the entrance.
I have been “looking underfoot” for a long time, but I was strongly attracted to the sense of material selection.
I was strongly attracted by the sense of the choice of materials.
I felt the harmony of the design of the stone.

【旭川近郊・東川「ワーケーション」発展 旭川2022家づくり探訪-3】




旭川近郊・東川は近年、本州地域からの「半移住」的発展が語られている。
感染症の拡大によってテレワークが日常的に普遍化して
仕事の環境としてとくに首都圏中心地の利便性優先思想が減衰し、
それに替わって自然環境の豊かな地方でしかも交通インフラがある地域、
という発展要因が注目され始めている現実。
東川地域は、旭川空港からのアクセスで首都圏からの交通は
確保されている。なんと言っても豊かな自然環境に没入できることから
注目度が高まってきているのですね。
いまワークとバケーションの合体造語であるワーケーションが注目されている。
地域に本社を置く「北の住まい設計社」さんは、家具製作などで
全国へのアピールもされているので、そういうユーザーとの関係性も高く、
最近は本社近くの自然林地域に自然最優先のような「住宅地」を開発している。
この住宅はそうしたもののひとつ。
施主さんは本州地域の方であり、不定期にこの建物を使うけれど、
管理保全なども同社に依頼しているのだということ。

敷地は周辺道路のやや高台に位置していて無舗装道路。
自然の起伏がそのままに展開しているので、
いわゆる大規模住宅地開発行為は行われていないと推測されました。
建物は平屋で周辺の樹木に対してその高さを対応させている。
道路面からはやや下った位置に建物配置。
屋根雪に対して「雪止め」を付けて堆雪屋根としている。
上の写真はメインルームの様子。
東川の自然林の眺望に対して、薪ストーブが端正に配置されている。
周辺の森は松と落葉樹の混交林。
四季折々に北海道らしい表情を見せてくれている。
交通ネットワークが拡大し飛行機の便が飛躍的に向上したことで
従来とは違った首都圏地域からの半移住というニーズが生まれているのです。
このメインルームの佇まいには求まられている「癒し」が端的に表現。
こうしたニーズへの対応には首都圏大手デベロッパーなどが
市場ニーズ把握を通してこれまでは占有的だったけれど、
北海道では地域の作り手がこのように優勢に対応できている。
まだニーズの総量が大量生産・大量販売レベルではないことを表している。

また、今後そういうニーズが拡大していっても
住宅技術、デザイン表現力どちらをとっても
大量販売型の住宅メーカーに強い占有力が働くとは思えない。
マーケティング視点からはむしろデベロッパーが地域ビルダーと手を組む可能性。
小さいけれど、やや未来的なニーズに対して市場が今後どう展開するか。
北海道の各地域では今後ともこのような住宅市場が拡大する可能性がある。
いまは限定的な動きだけれど、北海道各地域の豊かな自然の魅力は強い。
ニーズ自体が個別的・個性的に展開するのではないか。
たしかにワーケーションには「働き方改革」的な要素もあり
発注者の企業体も個性的な空間表現を望むと思われる。
北海道として今後大いに期待していきたい動向ですね。

Asahikawa 2022 House Building Exploration-3] Asahikawa Suburbs, Higashikawa “Work Vacation” Development Asahikawa 2022 House Building Exploration-3
Work+vacation is emerging as the leading edge of telework for companies and individuals in the Tokyo metropolitan area. The need for individualization of warm rooms and a sense of nature. The need for warm rooms and a sense of nature.

In recent years, the Asahikawa suburbs and Higashikawa have been described as developing in a “semi-migrant” fashion from the mainland area.
The spread of infectious diseases has made teleworking universal on a daily basis.
The idea of prioritizing convenience, especially in the center of the Tokyo metropolitan area, as a work environment has been waning, and the rich natural environment has replaced it.
Instead, regions with a rich natural environment and transportation infrastructure are beginning to attract attention.
In the Higashikawa area, the Asahikawa region is a prime example.
The Higashikawa area is accessible from Asahikawa Airport, and transportation from the Tokyo metropolitan area is
Asahikawa Airport. The Higashikawa area has been attracting more and more attention because of its rich natural environment, and the fact that it can be immersed in a rich natural environment.
This is why it is attracting more and more attention.
Nowadays, workcation, a coined word combining work and vacation, is attracting attention.
Kita no Sumai Sekkeisha,” a company headquartered in the region, has been making furniture and other products that are appealing to the whole country.
The company has a strong relationship with such users, as it also appeals to the whole country through furniture production and other activities.
Recently, the company has been developing a “residential area” in a natural forest area near its headquarters, where nature is given top priority.
This housing is one of those.
The client is from the Honshu area and uses the building on an irregular basis.
The site is located on a slightly elevated plateau on the surrounding road.

The site is located on a slightly elevated site with no paved road.
The natural undulations of the land have been left untouched, so there is no need to develop the site in a large scale residential area.
We assumed that no so-called large-scale residential development activities had been carried out on the site.
The building is one-story and its height corresponds to that of the surrounding trees.
The building is located slightly below the road surface.
The roof is designed as a composting snow roof with a “snow stop” for snow.
The photo above shows the main room.
The wood stove is neatly placed against the view of the Higashikawa natural forest.
The surrounding forest is a mixed forest of pine trees and deciduous trees.
The forest shows us the typical expression of Hokkaido in each of the four seasons.
With the expansion of the transportation network and the dramatic improvement in air travel
A need has arisen for semi-migrants from the Tokyo metropolitan area, which is different from the past.
The appearance of the main room is a simple expression of the “healing” that is being sought.
In order to respond to these needs, major developers in the Tokyo metropolitan area and others have been working on the development of semi-migratory apartments.
In the past, they have been possessive in their understanding of market needs, but in Hokkaido, they are now taking the lead in this way.
In Hokkaido, however, local makers have the upper hand in responding to these needs.
This indicates that the total volume of needs is not yet at the level of mass production and mass sales.

And even if such needs expand in the future
I don’t think that mass-market homebuilders will have a strong hold on the market in terms of either housing technology or design expression.
I don’t think that mass-market homebuilders will have a strong position in the market.
From a marketing perspective, there is a possibility that developers will join forces with regional builders.
How will the market develop in the future to meet the small but somewhat futuristic needs of the market?
There is a possibility that this type of housing market will continue to expand in each region of Hokkaido.
Although limited at the moment, the rich natural attractions of the various regions of Hokkaido are strong.
The needs themselves may develop in individual and unique ways.
Workcations may indeed be an element of “work style reform,” and each corporate entity may also have its own unique space.
It is likely that each corporate entity would like to see unique spatial expressions.
This is a trend that we in Hokkaido have great expectations for in the future.

【民家2.0〜性能向上と利便性進化 旭川2022家づくり探訪-2】





昨日の続篇、美瑛の新築by（株）創樹さんの家です。
日本人の伝統的住宅、民家を探訪して気付く暮らしぶりと
対比的に現代住宅を見返す視点を持っていると、
いろいろな気付きが得られる。いわば「民家2.0」。
外観的には断熱気密技術の向上によって「シンプル化」が顕著。
家という概念を小児に描かせたら、四角い本体に三角の屋根を描くのが
長い人類経験知の結果表現だと思うけれど、
北海道の家づくり経験での無落雪・陸屋根主流の現実からは、
この部分でのギャップも今後は注意深く見ていく必要がある。
無落雪・陸屋根という形状が優位型になって三角屋根が傍流になるときに
それが一種の建築的「方言」となっていくのか、さて。
この未来予測についてはよくわからないと思われます。
一方で、内観的にはワンスパンの大空間化が志向されてきたと思える。
これもこれまでの間仕切り装置としての建具類も省略化が顕著。
「引き戸」という概念すら減衰し、ドアも工業製品化が進行している。

そして生活利便性では各種の電化製品が暮らしの革新をもたらした。
その最たるものは水回り関連の設備機器。
先日わが家では給湯設備の更新を迫られたけれど、
そのときにいかに現代生活が設備機器に依存しているか、思い知らされた。
現代生活はエネルギーと設備機器に基本的に規定されていると実感。
生命維持装置としてのキッチン周辺と、水と熱源の集約した水回りが
その生活利便性を大きく支えている。
こういった「設備選択」要素の拡張が顕著なのだと思う。
そしてワンスパン的内部空間の中では、それらの配置的自由度も高い。
さらに最近の強い傾向として、玄関の２スパン化が進行している。

工業製品としての履物の多様化が生活装置に反映して
これまでの「靴箱」収納ではとても対応不能になって来て
いわば玄関の収納要素が独立的空間化してきている。
「オモテ」玄関と「お勝手」的玄関の現代的仕分けとも言えるのか。
結果として土間空間が拡大しつつあるとも言えるだろうか。
きのうのブログ記事に対して収納すべきグッズ類による家屋領域侵略が顕著で
既存の空間仕分けがドンドン「用途変更」を余儀なくされている、
というようなご意見も寄せられていた。

現代生活の進化というのはこうした設備と多様化するグッズ類の
大量拡大という趨勢を反映して行かざるを得ないけれど、
昔人の民家空間と比較対照してみると、さてこのまま進行していくのか不明。
グッズ類はその使用途と随伴している方が使い勝手がいいので
自ずと集中化が要望されるけれどそうするとその部分の面積拡大が派生する。
結果として既存の和室空間という「家系象徴」空間は姿を消していく。
こういうのに歯止めが掛かるのか、もっと拡大するのか
さて、あしたはどっちか？

Minka 2.0 – Performance Improvement and Convenience Evolution Asahikawa 2022 House Building Exploration-2
The future shape of the modern house from the perspective of the old minka. Is the reality of “Minka 2.0” evolution underway now? by …

This is a continuation of yesterday’s story, a newly built house in Biei by Souki Co.
The traditional Japanese house, the way of life that we notice when we explore a minka (private house)
and the way of life that we notice when we explore traditional Japanese houses and minka, and
I am sure you will gain a variety of insights. In other words, “Minka 2.0”.
In terms of the exterior, “simplification” is noticeable due to improvements in insulation and airtightness technology.
If we were to draw a child with the concept of a house, we would draw a square body with a triangular roof.
I think it is the result of long experience and knowledge of mankind.
However, the reality of the mainstream of snowless and flat roofs in my experience of building houses in Hokkaido, Japan, has led me to believe that the gap in this area will also be carefully observed in the future.
However, the reality of snowless and flat roofs, which is the mainstream of house building in Hokkaido, requires us to look carefully at the gap in this area in the future.
When the snowless, flat roof becomes the predominant form and the triangular roof becomes the sideline, it will become a kind of architectural “dialect”.
When the triangular roof will become the dominant form, will it become a kind of architectural “dialect,” or not?
It seems that we don’t know much about this future prediction.
On the other hand, it seems to me that the interior has been oriented toward one-span large spaces.
This is also marked by the omission of fixtures and fittings as partitioning devices.
Even the concept of a “sliding door” has declined, and doors are increasingly becoming industrial products.

In the area of lifestyle convenience, a variety of electrical appliances have revolutionized our lifestyles.
The most prominent of these are water-related appliances.
The other day, we were forced to update our hot-water supply system.
It made me realize how much modern life is dependent on appliances and equipment.
I realized that modern life is fundamentally defined by energy and equipment.
The kitchen area as a life-support system and the water and heat source
and the water and heat source are the major contributors to the convenience of modern life.
I think that the expansion of these “facility selection” elements is remarkable.
And within the one-span interior space, there is a high degree of freedom in the placement of these elements.
Another strong recent trend is the trend toward two-span entrances.

The diversification of footwear as an industrial product is reflected in our living equipment.
The conventional “shoe box” storage is no longer sufficient.
The storage element of the entranceway has become an independent space.
It could be said to be a modern sorting out of the “front” entrance and the “private” entrance.
Or perhaps it could be said that the space between the ground floor is expanding as a result.
In response to yesterday’s blog post, the invasion of house space by goods to be stored is remarkable.
The existing space is being forced to “change its use” as a result of the invasion of the house by goods that should be stored.
The evolution of modern life is a result of the evolution of these facilities and the evolution of the space.

The evolution of modern life reflects the trend of mass expansion of these facilities and diversified goods.
The evolution of modern life is a reflection of the trend toward the mass expansion of such facilities and diversified goods, but
However, when we compare and contrast this trend with that of the traditional private house, it is unclear whether it will continue to progress in the same way.
Goods are more convenient when they are used in conjunction with their intended purpose.
The goods should be centralized, but this would require an expansion of the area of the room.
As a result, the existing Japanese-style room space, a “symbolic space of the family lineage,” is disappearing.
Will there be a halt to this kind of thing, or will it expand further?
Well, which will it be tomorrow?

【美瑛の家 旭川2022家づくり探訪-1】




北海道の工務店グループ・アース21の久しぶりの地方現場見学会。
これまで大体年に５−６回のペースで行われてきた
「イマドキ北海道の家」現場見学の貴重な機会。
Zoomやオンラインでの情報交換会もそれはそれで意義があるけれど、
住宅って言うのは空間を創造する人間営為なので、やはり
カラダで感じる気付きや感覚がまさにコアの部分だと思います。
コトバでは伝わらない核心部分はそういった領域であって
それをお互いに確かめ合いながら、研鑽を積んでいくことが重要。
同じ北海道内でも、いくつか地域的な風土の違いがあって
そのなかでもっとも寒冷でしかも多雪という条件下にあるのが旭川・道北。
それだけに高断熱高気密・住宅性能の要件が決定的な地域性。
北海道の住宅研究組織「北総研」も本部が旭川にある。
そうした旭川の家づくりの中核メンバーの最新動向であります。

１軒目は（株）創樹さんの美瑛の家。
わたしのブログでは本州地域などの伝統的古民家などの取材が多いのですが
そういった探訪と対比的にイマドキの北海道の家の違い。
暮らし方の部分での大変革があったのだということが明瞭。
端的には和室がほぼ北海道では消えてしまって、
現代の「世界標準」の暮らし方に準拠した家づくりだと思える。
約25坪弱の１階間取り図を掲載しましたが、
基本的には開放的な間取りが特徴と言えるでしょうか。
玄関入り口は外部から若干の高低差が付けられ、しかも
囲うように屋根・壁が張り出して雪対策としている様子がわかる。
外壁には耐候性を考慮して金属外皮が採用されている。
凹凸の少ないシンプルな外観形状で、屋根は陸屋根でフラットルーフ。
落雪配慮よりも合理的な「乗っけたまま」の雪対応。
屋根の小屋組で剛性を高めるのが150年の北海道の寒冷地住経験の一般解。
これは非常に重要な変化要素だけれど、よくエトランゼのみなさんから
「屋根、ないんだ・・・」と驚かれることがある。
屋根を省力すると、外観的な「バランス」要素は窓の配置が大きくなる。
四角い外観に対して表情を演出していくのは窓となるのですね。
敷地が比較的に大きめでクルマ駐車スペース的には２台が標準的。
雪のことを考えて塀は存在せず、庭もあまり「付随的」とは言えない。

そして室内では基本的に「間仕切り壁」というのは消えていく。
というのは室内の空気環境をコントロールし、均質な室内気候を
実現していくためにはワンルーム感覚の方がハンドしやすくなる。
「動線」はあるけれど「廊下」というハッキリしたゾーン分けは乏しい。
玄関で靴は脱ぐけれど、やはり「世界標準」的ライフスタイルと思えますね。

Biei House Asahikawa 2022 House Building Exploration-1
A “world standard” lifestyle realized after 150 years of exploration of Hokkaido’s living environment. A simple-is-best philosophy to cope with the difficulties of winter snowfall. Biei, Hokkaido

This is the first regional site tour in a long time for the Hokkaido construction company group Earth 21.
The tour has been held approximately 5-6 times a year so far.
This is a rare opportunity to see the “Imadoki Hokkaido House” site tours, which have been held approximately five to six times a year.
While Zoom and online information exchange meetings are meaningful in their own right
However, since a house is a human activity to create a space, it is important to have the
I believe that the core of the process is the awareness and sensation that we feel in our bodies.
It is in these areas that the core cannot be conveyed by words.
It is important to study and study while mutually confirming this.
Even in Hokkaido, there are some regional differences in climate.
Asahikawa and northern Hokkaido have the coldest climate and the most snowfall.
Therefore, the requirements for high thermal insulation, high airtightness, and housing performance are critical in this region.
The Hokkaido housing research organization “Hokusoken” is also headquartered in Asahikawa.
Here are the latest developments of the core members of Asahikawa’s house-building community.

The first house is Souki’s house in Biei.
In my blog, I often cover traditional old houses in the Honshu area.
In contrast to such explorations, there was a big difference in the way of living in Hokkaido.
It is clear that there has been a great change in the way of living in Hokkaido.
In short, Japanese-style rooms have almost disappeared in Hokkaido.
The house seems to be built in conformity with the modern “world standard” way of living.
I have included a floor plan of the first floor of the house, which is just under 25 square meters in size.
Basically, I would say that it is characterized by an open floor plan.
The entrance is slightly elevated from the outside, and
The roof and walls are designed to protect the house from snow.
The exterior walls have a metal skin for weather resistance.
The exterior shape is simple with few irregularities, and the roof is flat with a flat flat roof.
Snowfall considerations are more rational than snowfall considerations, and the snow response is “leave it on”.
Rigidity is increased by the roof’s shed structure, which is the general solution based on 150 years of experience living in cold regions in Hokkaido.
This is a very important change factor, but I often hear from people in Etranse
I am often surprised by the fact that they do not have a roof.
When the roof is reduced in size, the “balance” element of the exterior is the arrangement of the windows.
So it is the windows that create expression to the square exterior.
The site is relatively large, and two cars are standard in terms of car parking space.
There is no fence for snow, and the garden is not very “incidental.

And indoors, “partition walls” will basically disappear.
This is because in order to control the indoor air environment and achieve a homogeneous indoor climate
It is easier to handle a single room in order to control the indoor air environment and to realize a homogeneous indoor climate.
Although there is a “line of flow,” there is not a clear division of “corridor” into zones.
Shoes are taken off at the entrance, but it still seems to be a “world standard” lifestyle.

【水回りがキレイだと好印象 東京町田「浮輪寮」探訪-5】


さて工事途中にお邪魔して、勝手に探訪記シリーズ。
迷子になったことがトラウマのようで仇討ちと全５回になりました。
ルポを許諾していただいた丸谷博男さんのご好意に感謝です。
工事途中の写真撮影なので眼光紙背に徹するように
ほぼ個人的関心に沿って書き連ねてみましたが、
さすがに荷物類がたくさん映っているので
そのなかでもまともな部類の写真に絞って掲載してみました。
外観はシンプルな造作ですが、平屋に乗せた屋根がアクセントになっていて
均整が取れていて見ていて落ち着いた印象。
この屋根の小屋裏はどうなっているのか、
図面を確認する限り、空気集熱装置をスタンバイしていると思われます。

内観でも主要空間の和室以外の箇所については不分明でした。
そういう中で、水回りについてはほぼ進捗が見られていた。



床面の新造作が姿を現していたので、
その雰囲気を感じられた次第。
設備の選択と配置、そしてその空間の雰囲気との対比。
毎日使われ、それも多くの来訪者が使うことを考えて、
やや非日常感とそこでの体験に補助線を引くような役割を
水回りには担わせているのかも知れません。
個人的に、床面のタイルカーペットのデザインと設備のコントラストが
「キレイ」と清潔の間をゆらいでいるような印象を受けていました。
旧宅からの塗り壁に囲まれた洗面も対比的で
むしろ「水」の役割を引き立てているように感じられた。
未完成の工事現場のような空間でしたが、
それを超えて設計意図やら、環境との相互関係を中心にルポ。
書いてみるとそれなりに自分としても面白い気付きを得られた。
やはり建築、住宅を作って行く営為というのは
実にたくさんの選択行為の積み重ねであり、その多様な選択肢から
ある手段を選択して改変が加わっていくことに「寄り添う」というか、
そういう本質部分を対話的に解剖してみる、みたいな気付き。
考えて見ると、古民家というものの取材と似ているかも知れない。

最近、温暖地域の住宅、古建築などの事例が多かったのですが、
一昨日まで北海道旭川で北海道の地域工務店グループ・アース21の
現場見学会が久しぶりに開催されておりました。
また、ブログを応援していただいている方から
「養蚕民家」を建設した開拓者の古建築情報もいただき、
それらを、明日以降掲載予定です。
つくづく感じるのですが、やはり住宅は現場感覚が非常に重要。
なんといっても空間についてのコミュニケーションなのですから
リアルな空気感を感受しながらのルポが基本。
やはり「日常を取り戻す」ことが大切だと痛感しています。

English version⬇

Cleanliness of the water area gives a good impression.
The key to on-site interviews is the points that you notice there. The basic principle of “communicating” is to always be sensitive to information. …….

Well, I visited you in the middle of construction and took the liberty of writing a series of exploratory notes.
It seems to have been a traumatic experience to get lost, and it became a total of five times with a vengeance.
I would like to thank Mr. Hiroo Marutani for his kindness in allowing me to do this reportage.
Since I was taking pictures during the construction process, I tried to keep my eyes on the road.
I have tried to write mostly according to my personal interest.
As you can see, there is a lot of baggage in the picture, so I thought it would be a good idea to show some of the baggage.
I have tried to focus on the decent photos among them.
The exterior is a simple structure, but the roof on the flat roof is an accent.
The roof is well-proportioned and gives a calm impression.
I wondered what was going on behind this roof.
From the drawings, it is assumed that an air collector is on standby.

Even in the interior view, I was unclear about the other parts of the main space except for the Japanese-style room.
In such a situation, progress was mostly made on the water area.

The new flooring had been revealed.
the atmosphere of the space.
The choice and placement of equipment and its contrast with the atmosphere of the space.
Considering the fact that the room will be used every day and by many visitors
the role of the water feature is to create a somewhat unusual feeling and to draw an auxiliary line to the experience of the space.
and the water feature may play a role in creating an extraordinary experience.
Personally, I think the contrast between the design of the carpet tiles on the floor and the facilities
I had the impression that the contrast between the design of the carpet tiles on the floor and the equipment waver between “clean” and “cleanliness.
The washroom surrounded by painted walls from the old house is also a contrast.
It seemed to enhance the role of “water” rather than the other way around.
The space looked like an unfinished construction site, but
Beyond that, the reporto focuses on the design intent and the interrelationship with the environment.
I found myself making some interesting discoveries when I wrote the report.
After all, the act of building architecture and housing is
The act of building architecture and housing is really an accumulation of many choices.
I would like to “lean in” to the process of selecting a certain means of alteration from among the various options.
I realized that I would like to try to dissect such an essential part of the process in an interactive manner.
When I think about it, it may be similar to the coverage of old private houses.

Recently, I have been working on many cases of houses and old buildings in warm regions.
The day before yesterday, a site tour was held in Asahikawa, Hokkaido, for the first time in many years by Earth 21, a Hokkaido regional construction company group.
The site tour was being held in Asahikawa, Hokkaido, for the first time in a while.
We also received a message from one of our blog supporters
We also received information from a blog supporter about the pioneer who built a “silkworm farm house,” and will be posting it tomorrow and onward.
We are planning to post them from tomorrow onward.
I always feel that the sense of site is very important in housing.
After all, we are communicating about space.
Therefore, it is important to report on the project with a realistic sense of the atmosphere.
I am keenly aware of the importance of “getting back to the everyday.

【和の大開口と北海道的ぼやき（笑） 東京町田「浮輪寮」探訪-4】




この建物を再生利用したいと丸谷さんが考えただけあって
その構成素材の素性には和風建築としての格調が感じられます。
写真の空間は水盤に面したメイン居室の座敷２間。
ふすま建具で仕切られたものが開放されみごとな広間が広がる。
周囲の植栽・森の様子らが水盤をも演出装置として座の目線で楽しめる。
いかにも日本の伝統的高級住宅手法が全開している。
近接した自然を建物の内部にまで引き込むという日本人の発想を感じる。
春夏秋の３シーズンで周囲の自然と完全に一体化することを
花鳥風月思想、あるいは老荘思想として和の精神性と感じ続けていた。
「冬さえガマンすれば・・・」という四季への感覚。
開口部の緩衝装置としては障子と非常時用の雨戸程度で、
あくまでも眺望最優先の思想になる。
なので「家は庭があってはじめて家庭なのだ」みたいな生活哲学になる。
一方北海道住宅は冬には大量の積雪で庭木が雪でやられる不安が大きく
庭のキャンセル率が高くなっている。
一生懸命に庭仕事に努力しても、楽しめる時間はせいぜい半年。
北海道人にしてみれば豊かな大自然との対話は１方向からの眺望で十分で
外にちょっと出ればいやでも視線に飛び込んでくると考える。
大空と自然との対話は１方向の窓からもダイナミックに感じられる・・・。
もし大開口空間を作るときには「開く」と「閉じる」の対話作業。
寒冷地での熱環境的には２面の開口部が全開している状態は難しい。
日射取得効果と３重ガラスの性能で熱環境のバランスを考えることになる。
和の眺望空間は高断熱住宅を見続けている人間としては、飛躍した空間。
浮輪寮は建築の用途が「IDEA CENTER」ということで非住宅。
発想の自由度を第１に考えた建物として古建築の美感を受容したのでしょう。
こういう開放型空間でやさしい気候環境と対話したいと考えるのは自然。
北国人としてはこういう自然との対話志向性を理解しつつ、
気候風土と調和させるにはどうしたらいいかと知恵と工夫で立ち向かう。
そういうハンデキャップレースはそれなりに楽しい（笑）。
「拡張された花鳥風月」をどうやったら北海道は獲得できるか、
こういうテーマ設定はなかなか無限に蠱惑的かと。

こういうあたりの居住環境性について
東京町田の環境の中で、春夏秋の季節感と冬対応をどうされているのか、
どんな試行をされているのか、機会を見てぜひ取材したいと思っています。
ただやはりわたし的には日本人なので、蒸暑の夏などに
こういう空間美のなかで感じる花鳥風月に憧憬する部分は大きいです。
失って知る、民俗記憶のなかのいごこちの良さみたいなものか。

English version

A Japanese-style large opening and Hokkaido-style blurring (laughs) Exploration of Tokyo Machida “Ukirinryo” – 4
A space in which the Japanese concept of “Kacho-fu-getsu” (flowers, birds, winds, and the moon) is abstracted. Hokkaido people, who are not able to perceive the same things in the same way, are oriented toward the “expansion of Kacho-fu-getsu” by force. …

Mr. Marutani wanted to revitalize this building.
The materials used in its construction are of a Japanese architectural quality.
The space in the photo is the two tatami rooms of the main living room facing the water table.
The room is divided by fusuma fittings, which are then opened to reveal a magnificent spacious room.
The surrounding plants and forest can be enjoyed from the viewpoint of the water table as well.
This is a traditional Japanese luxury residence in all its glory.
The Japanese concept of drawing nature into the interior of the building is very much in evidence.
The three seasons of spring, summer, and fall are to be completely integrated with the surrounding nature.
I have always felt that the idea of “Kacho-Fu-Getsu” or “Lao-Zhuang” is the spirituality of harmony.
The sense of the four seasons, “If only we could endure winter….
The only buffer devices at the openings are shoji screens and emergency storm shutters.
The view is the highest priority.
Therefore, the philosophy of life is that “a house is a home only if it has a garden.
On the other hand, in Hokkaido, there is a great deal of snowfall in winter, and there is great concern that the garden trees will be damaged by the snow, resulting in a high rate of garden cancellations.
The cancellation rate of the garden is high.
Even if you work hard on your garden, you can only enjoy it for half a year at most.
For Hokkaido residents, a view from one direction is enough to interact with the abundant nature.
If you go outside for a moment, it will jump into your line of sight.
The sky and nature can be dynamically felt even from a window in one direction….
If you create a large-opening space, it is a dialogue between “open” and “close”.
In terms of thermal environment in cold regions, it is difficult to have two side openings fully open.
The balance of thermal environment is to be considered in terms of solar radiation acquisition effect and triple glazing performance.
The Japanese view space is a leap forward for someone who has been looking at highly insulated houses.
