An octagonal spiderweb-shaped structure is covered extending down from the top section to the supporting legs to create a centripetal single-room space. Family members may freely engage in their favorite activities in an open space/corridor.

This is a house for a family of four in a suburban residential area developed in a hilly area.
The surrounding environment is a uniform landscape of houses built parallel to a plot with a certain aspect ratio characteristic of subdivisions. The site sits along the road on the north side, and the east and west sides are situated along a slope with a slight difference in elevation from the neighboring lots.
The site is also characterized by a tiered topography created by a large difference in elevation to the south.
Considering that the lot below the southwest side of the site is vacant, the entire volume is configured at a 45-degree angle to the site to create an expansive environment with desirable views, ventilation, natural light, and privacy.
Specifically, an octagonal spider-web-shaped structure is covered extending down from the top section to the supporting legs to create a centripetal single-room space.
The legs are supported at four points, and the inside and outside are connected via triangular openings joining the vertices between the fulcrums. Inside the 77 square meters of open space, four boxes, which are not rooms, are arranged to create a corridor-like area that functions as the family room and living space. In other words, there are no enclosed individual spaces here, but family members may freely engage in their favorite activities in an open space/corridor.
The space might be in a neat and tidy state or in complete disarray. Since no structure defines a given area as a room, the areas and patterns within the space will likely change over time as the children grow and with other changes in family life.
It is a house with strong architectural features that embrace changes in the daily life of a family with a unique lifestyle.

領域が伸縮するおおらかな環境
丘陵地を開発した郊外の住宅地に建つ家族４人の住まいである。周辺環境は、分譲地特有の縦横比をもった区画に対して平行に建てられた住宅群が画一的な風景をつくっている。敷地は北面道路に接道し、東西は坂道に沿った状態で隣地とは僅かな段差を伴っている。南面に対しては大きな高低差がつくる雛壇形状が特徴的な場所である。
計画にあたり、南西面の崖下が空地ということもあり建築全体を敷地に対して45度振った配置にすることで眺望・通風・採光・プライバシーを確保したおおらかな環境を考えた。
具体的には八角形の蜘蛛の巣状の架構を頂部から脚部へ向けて覆い被せることで求心的な一室空間としている。脚部は4点で支え、支点間の頂点を結んだ三角形の開口によって内外を繋ぐ。延床77㎡の内部には4つの箱を配することで生まれる余白が、家族共有の居場所として機能する。さらに各々の箱もアルコーブのような居場所として開かれており、個人の趣味が溢れた露地もしくは廊下ともいえる場所と合わせて家族が自由に過ごす。
整然とした状態もあれば、散らかって足の踏み場もない状態もあるだろう。部屋という領域を規定するものがないため、長い時間の中で子供の成長や家族の変化に合わせて露地を形成する範囲や模様も変化していくだろう。
暮らしのかたちに対して柔軟な考えをもった家族の日常を包含する、建築的強度をもった住宅である。
