Overview

プロジェクトの概要
A house where the residents become the builders
住まい手が、つくり手になる家
A house for a parent and child in Okazaki who run various community-based projects. Because the clients wanted to know where the materials come from and how a house is built, NESTING, in which the clients build everything from the foundation to the finishes themselves, was adopted. Emphasizing relationships within the community, local friends and acquaintances also took part in construction alongside the family.
住まい手が、つくり手になる家
岡崎市でコミュニティを軸にした様々なプロジェクトに取り組む親子が建主の住宅。住宅の材料の出どころや建設方法を知りたいという建主の意向から、基礎から仕上げまでを建主自ら施工する「NESTING」を採用した。地域内での関係性を重視し、家族に加えて地域の友人・知人も施工に参加した。

The clients also took part in felling timber in the forest and assembling the ShopBot. All solid wood, from structure to finishes, is from Okazaki and was machined on a ShopBot in the city. More than 80 people in total took part over the three-month construction period.

The foundation uses the Spike Frame method with driven steel pipes, incorporating a mechanism to jack it up if the soft ground settles. Because the site falls within a fire-spread line, siding was applied to the exterior for fire protection and finished with rattan.

The sections show the floor built up on a steel sill and a timber sill, resting on a Spike Frame foundation of steel pipe piles and adjustable posts.

図版

基礎は単管を打ち込むスパイクフレーム工法とし、軟弱地盤に対応するため、地盤沈下時にジャッキアップできる機構を組み込んだ。延焼ラインにかかるため外壁にサイディングを張って防火構造とし、その上をラタンで仕上げた。

断面図は、単管杭と調整支柱からなるスパイクフレーム基礎の上に、鉄骨土台と木土台を重ねて床を組む構成を示している。
