「群れ」の住まい 

3世代の6人が共に暮らす112m2の住まいである。

海沿いの明るく陽気な雰囲気をもつ住宅密集地で、戸建て住宅で囲まれた袋小路の突き当たりに敷地はある。親世帯が住んでいた住まいを、子世帯3人・親世帯3人の合わせて6人のための住まいへ建て替える計画だ。子世帯の夫婦は近所で美容室を営んでおり、小学生の子供は祖父母と多くの時間を過ごす。親世帯は自宅を仕事場としたり都市部へ出たりなど、6人の暮らし方や関係性は多様であった。

われわれは、6人がそれぞれ自分の居場所を見つけ個性ある過ごし方をしながらも一緒にいられるような住まいを考えることとした。魚の「群れ」が集まったり離れたりを繰り返しながらゆるやかなまとまりをつくるような住まいのかたちだ。

建築は全体をグリッド状に構成しつつ部分的に柱を抜いたり梁にズレを設けることで、空間に連続性と一体感のある広がりをもたせた。そして半地下から屋上へ動線が抜けていく５層のスキップフロアとした。床の高低差でできた視線のズレは小さな居場所をつくり、その境界には腰かけたり、もたれかかったりといった身体的なふるまいが生まれ多様な暮らしの風景が広がる。また、南北の庭をつなぐ空間構成は、周りの密集する住宅の親密な雰囲気やそれらが南側にもつ小さな庭の緑の環境を内部に引き入れる。

1階は前庭に面した縁側と掃き出し窓により街と連続した場所となり、子供が友達と内外を行き来して遊んだり、庭いじりをする隣人たちと会話が生まれる場となるだろう。中間階には食堂や水回りを配置した。食堂にある大きなテーブルは、食事や勉強、家事や仕事など、異なる生活リズムで同時に過ごせる場所となる。そして半地下階と2.5階には4.5〜7.3m2ほどの小さな室を設けた。建具や可動家具の開閉によって室同士を連続させたり、共用空間との繋がり方を選択できる。住まい手の性質や住まい方が変化しても柔軟に住まうことができるだろう。

建物の角には2方向に開かれた窓を、空間を巡ると必ず視線の先に外の風景が目に入るよう配置した。多方向から光が差し込み、風がさまざまな方向へと通り抜け、それぞれの居場所には時間や季節ごとの多様な特徴がもたらされる。それと共に、ひとつの場所に集まっていても視線が分散され、お互いの意識にはちょうどよい距離感が生まれるだろう。

そうして家族や社会の変化に呼応しながら姿形を変えていくような「群れ」としての６人の住まいになることを期待している

This 112m2 house is designed for six people across three generations living together. The site is located at the end of a cul-de-sac, surrounded by detached houses in a densely built residential area by the sea with a bright atmosphere. The project involves rebuilding the original home—previously occupied by the grandparents—into a new residence for the entire family: three members from the younger generation and three from the older. The younger couple runs a hair salon near their home, and their child spends much of their time with the grandparents.The older generation splits their time between working at home and going into the city. The six family members lead diverse lifestyles and have varied relationships with one another.

 

Our goal was to design a home that allows each person to find their own place and live in a way that suits them, while still being able to spend time together comfortably. We envisioned a home thatresembles a school of fish—gathering and dispersing freely, forming a loose yet cohesive collective.

 

The architecture is organized on a grid, but some columns are intentionally omitted, and beams are staggered to create continuity and a sense of unity in the space. The house is composed of five split levels, from a semi-basement to a rooftop, connected by a vertical circulation route. The difference in the line of sight created by the difference in floor height generates small places of residence, and the boundary between these places generates physical activities such as sitting or leaning on the floor to create a diverse landscape of living.

 

The spatial configuration connects the north and south gardens, drawing in the intimate atmosphere of the surrounding neighborhood and its small southern-facing gardens. On the Ground floor, a balcony and large sliding doors open to the front garden, forming a seamless connection with the street. This becomes a place where the child can move freely between inside and outside with friends, and where conversations naturally occur with neighbors tending to their gardens.

 

The first floor houses the dining area and utilities. A large dining table in the center becomes a multifunctional hub, meals, study, housework, and even working remotely. It is a space where various daily rhythms coexist harmoniously.

 

The semi-basement and the third floor each include small rooms of about 4.5 to 7.3 square meters. These rooms can be connected to each other or to shared spaces using sliding doors and movable furniture, allowing residents to adjust their level of openness and privacy. The house is thus able to adapt to changes in its inhabitants and their ways of living over time.

 

At the building’s corners, windows open in two directions, ensuring that views of the outside landscape are always present as one moves through the space. Natural light enters from multiple angles, and breezes pass through various paths, giving each place a unique quality that shifts with the time of day and season. This layout also helps distribute sightlines, allowing for a sense of comfortable distance among family members—even when they are in the same room.

 

We hope that this house will become a school of six people—a flexible, responsive home that evolves with the changes in family and society.
