時間を繋ぐ可変的空間
弱⇒強
計画地は最寄り駅から徒歩15分の住宅に囲まれた東京都中野区南台の旗竿地になる。収益物件としてはあまり恵まれた立地ではないため、(弱)昨今のライフスタイル多様性、生活水準の変化に対応できるように、容易に住戸の規模、間取りを変更できる計画とした。(強)
■外⇔半外⇔内
将来的な改修に対応するため、住戸間の界壁は乾式工法を採用し、床の仕上げは主に土間仕上げとした。居室の必要最低限の範囲を小上がりとして家具のように仕上げる事で、スラブ上での配線スペースを確保し、平面計画の自由度を確保した。居室までに至る土間は前面道路から敷地内通路を経由し、建物内部まで路地空間を取り込むことで、土間と居室が隣接した昔ながらの趣を残しつつ、外部空間、半屋外空間(屋内路地)と室内空間(家具)を曖昧に空間を分けた縁側のような室内空間を計画した。
■6⇒5⇒6?
着工当初、約23m²メゾネットを3戸、約32m²トリプレットを3戸の計6住戸で計画した。上棟の段階で、北側斜線がかかる居室の狭小感を改善するため、3住戸を2住戸に変更し、計5住戸とする計画に変更した。将来のために構成したシステムは、工事段階で実行する事になったが、実際に可変可能という事を証明する事ができた。元々あった1階の水廻りは将来的に6住戸に出来るように配管まで施工し、乾式にて床仕上げを施工する事で、施工性、低コスト性を考慮した。
■過去⇒現在⇒将来ネガティブな敷地(以前から存在する要素「過去」)にポジティブな建物(現状計画する建築物「現在」)を建て、その建物に+α(容易に改修できる仕組み「将来」)を含ませる事で、時間を繋ぐフレキシブルな建物を計画した。

A variable space that connects time
Located in Minamidai, Nakano-ku, Tokyo, the project was planned in the infill of a residential area, 15-minutes walk from the nearest station. Considering how blessed the location is, and how coveted it could become in the future development of the city, the priority was to guarantee a time adaptability, to respond to the possible upcoming changes, lifestyles diversity and living standards.
Therefore, the size and the layout of the housing units are modular to anticipate potential renovations. To enhance this adaptability, the boundary walls between each apartment are put in place thanks to a dry constructive method. Meanwhile, the floor is essentially kept as its structural appearance comparable to a “dirt floor”, reminding the old days when a real dirt floor was used for the living room. The minimum of finished floors are slightly raised above the slabs, to make them look like part of furnitures. This way, the wire space is placed in between the “dirt floor” and the finished floor, to ensure the flexibility of the plan. This “dirt floor” is the extension of the front road, it embodies the premises to capture the alley space inside the building and guiding us from the front road through the passage until the interior. The project was ambiguously divided into 3 zones embracing their proper status, an external space (threshold / veranda), a semi-indoor space (dirt floor), and an indoor space (furniture).
Originally, a total of 6 residential units were planned. However, during the construction process, we decided to increase the proportions of the living room facing the northern diagonal. From 3 units to 2, this change has been possible thanks to the system originally configured for the future. Implementing such a change during the construction phase has proved the applicable flexibility of the building. Thanks to non permanent installations such as pipes for the water supply on the 1st floor, dry method for the finished floors and walls, the project stands as a model of evolutivity for the time coming. The building is seen as a connector of time, supporting the past, present and future expectations. The future is a constant adjustment, where addition and subtraction are variables that can freely reshape the project’s layout.
