巡る間／Circularity Cabin

容易に解体・移築可能なサーキュラー建築／Circular architecture that can be easily dismantled and relocated.

敷地が都市計画道路に面しており、将来道路拡幅によって敷地がなくなってしまうかもしれないが、その日がいつ来るかわからないという状況下で、家族3人が暮らす住宅の設計を求められました。物価高騰や廃棄物の問題も考慮した結果、ホームセンターでも手に入る安価な規格材のみで構造体を構成し、プレカットは極力行わずにボルトで留めるのみの架構としました。あらゆるものをドライジョイントで構成し、将来の移築を容易にしています。万が一移築をしないとしても規格材をボルトの穴あけしたのみなので、他用途への転用も容易となるように考えました。 環境面では熱負荷を抑える為に、表面積が最小の立方体とし、窓も最大限絞り込み、3つのハイサイドライトを主体に光と風をコントロールしています。ハイサイドライトは環境シミュレーションによって位置をこの地に最適化していますが、移築先の環境に合わせて位置変更可能な様にディテールに配慮しました。

The site faces an urban planning road, and we were asked to design a house for a family of three, under the condition that the site might disappear in the future due to road widening, but we did not know when that day would come. After taking into account the rising cost of living and waste issues, we decided to construct the structure using only inexpensive standard timber, which is available at home improvement centres, and to bolt the structure together without any pre-cutting as much as possible. Everything is dry-jointed to facilitate future relocation. Even if the building is not relocated, the standard timber is only bolted and drilled, so it can be easily converted to other uses. In terms of the environment, the cube has the smallest surface area to reduce the heat load, the windows are as narrow as possible, and light and air are controlled mainly by the three high-sidelights. The position of the high-sidelights has been optimised for the site through environmental simulation, but consideration has also been given to detailing so that the position can be changed to suit the environment of the new location.

主採光・通風をハイサイドに頼ると、1階が暗く風通しが悪くなります。そこで、2階床を全面45mm角のスノコとし、上部からの光や風が1階に届くように考えました。全体を構成する部材を最小限に絞り込んでいる為、スノコにも地震力を負担させています。この住宅では内装仕上げがないので、構造体やスノコを固定しているボルトやビスが丸見えです。住宅の成り立ちが誰にでも一目瞭然であることを大事に考え敢えて見せています。万が一材の具合が悪くなった際にはホームセンターにて規格材を購入しDIYにて修繕も可能です。また、2階スノコ床にはベッドや棚などが置かれ採光・通風が妨げられますが、むしろ「夏は2階のベッドを西側に移動した方が1階のリビングが快適」など住まい手が自ら環境を形作ることを考え、環境シミュレーションにも織り込んでいます。環境を生活物でコントロールできるのは住まい手にとっての新しい価値となると考えました。

Relying on the high sides for main light and ventilation makes the ground floor dark and drafty. Therefore, the entire second floor is made of 45 mm square sunoko, so that light and ventilation from the top can reach the first floor. As the components of the overall structure have been reduced to a minimum, seismic forces are also borne by the sunoko. The house has no interior finishes, so the bolts and screws holding the structure and the duckboards in place are fully visible. The structure of the house is visible to everyone, which is important to us. In the unlikely event that the timber becomes unsound, it can be repaired as a DIY project by purchasing standard timber from a home improvement centre. The beds and shelves on the second-floor sunken floor obstruct lighting and ventilation, but we have also incorporated this into the environmental simulation, considering that the residents can shape their own environment, for example by moving the beds on the second floor to the west in summer, so that the living room on the first floor is more comfortable. The ability to control the environment with everyday objects was considered to be a new value for the residents.

住宅に限らずほとんどの建築物において、利用者が制御可能な環境は窓やカーテンの開け閉め、空調スイッチのオンオフ程度である。修繕なども多くの人にとっては容易ではない。この点に日頃から疑問を持っていた。
巡る間は、規格DIY材で構成し、解体容易性への配慮から部材点数を最小限とした結果、内壁はなく配管やビスやボルトが現わしとなり構成が一目瞭然となっている。不具合も一目瞭然な為、住まい手自らホームセンターに赴き大概のことは修繕可能だ。これは、サーキュラーエコノミーにおける「自ら修理し使い続ける権利」を担保するものである。加えて、2階のスノコ床の上に置く家具によって微気候をコントロールできることに気づいた。住空間においては家具が占める割合は大きいにも関わらず、環境シミュレーションで加味されることは稀である。そこで、季節ごとに衣替え感覚で住まい手が家具配置を変え、季節に合わせた快適性が得られる様に、着衣量や運動量もパラメータとして加味できるPMV（予測平均温冷感申告）の感度解析を行うファーニチャースケープシステムを実験的に構築し、微気候への感受性を高める工夫をした。

In most buildings, not only houses, the only environment that can be controlled by the user is the opening and closing of windows and curtains and the switching on and off of air conditioning switches. Repairs are also not easy for many people. This point has been questioned on a regular basis.
Circularity Cabin is made of standard DIY materials and the number of components has been minimised for ease of dismantling, so that there are no internal walls and the pipework, screws and bolts are visible, making the structure obvious at a glance. Defects are also obvious at a glance, so the residents themselves can go to a home improvement centre and repair most of the problems. This guarantees the "right to continue to use and repair by oneself" in the circular economy. In addition, we have noticed that the microclimate can be controlled by furniture placed on the second floor's sunken floor. Despite the fact that furniture accounts for a large proportion of the living space, it is rarely taken into account in environmental simulations. Therefore, a furnishingscape system that analyses the sensitivity of the PMV (Predicted Mean Temperature (PMV)), which can also take into account the amount of clothing and physical activity, was experimentally constructed to increase sensitivity to the microclimate, so that residents can change the furniture arrangement as they change their clothes each season and obtain comfort in accordance with the season.
