The house is for a family of three built on thenorthern corner lot of a gently-curving, tiered residential land.

The site is in a residential neighborhood and enjoys views of the peaceful landscape over the bank on its eastern side. While its southwestern sides are hemmed in by neighboring　houses, the land opens up in a fanshape towards the street on the northeastern side, giving it a unique character.

In this project, we repeated the curved space starting at the southwestern side as the

center point, expanding it from the inside to the outside towards the front road while

amplifying the walls in concentric circles. Furthermore, we used this unique site to revisit the concept of having no boundaries ― to envision the overall perspective by treating the surrounding green areas as part of the project's outdoor space.

Specifically, we extended the building volume so that it sits as close to the edge as possible within the allowable setback-line regulation. A large, arc-shaped wall stands along the site perimeter, creating a small garden that functions as a buffer between the inside and outside. We designed the wall as a massive mud-plastered wall with few openings; it floats 700 millimeters above ground, creating an interior-like space that works as an extension of the outside while also ensuring privacy. Additionally, the ever-changing sunlight from the south is projected onto the northeast wall, allowing the residents to feel the light in each room.

By building a small, three-dimensional landscape and a single large, floating wall within the small distance that lies between the family and the street, we believe we were able to create a vibrant living environment that helps the residents expand their scope of interaction while also satisfying their requirements.

領域を広げる弧状の浮遊壁

緩やかに湾曲する雛壇状の宅地北面角地に建つ家族3人の住まいである。

周辺環境は東面にある土手を挟んで住宅街が広がっており、敷地からも土手越しに長閑な風景を望むことができる。南西面を隣家に囲まれつつも、北東の前面道路に対して扇形に開かれた特徴的な場所であった。

今回の計画にあたり、南西を中心点に前面道路側に向かって同心円上に壁を増幅させながら、内向的居場所から外部へと弧状に切り取られた空間を反復させた。また、周辺の緑地帯を庭の延長として見立てることで、境界を曖昧とし、領域を広げるような形式をこの特異な敷地で試みた。

具体的には、道路斜線制限上可能な建築のヴォリュームを敷地境界際まで伸ばし、敷地形状に沿って立てた弧状の大きな壁との間に生まれた小さな庭を、内外のバッファーとして機能させた。このいくつかの開口を穿った物量のある土壁は、地表面より700mm程度浮遊させてプライバシーを確保しながら外部の延長としての内部のような空間をつくり出している。また弧状の形態は、刻々と変化する南からの陽光を北東壁面に映し出し、各居室で光の様相を感じることができる。

家族の居場所と道路境界までの僅かな距離を、小さな立体的ランドスケープと浮遊する大きな1枚の壁によって、人が関わりをもつ範囲を広げる、豊かな環境が生み出した。
