六光天井の家

House of Six Lightened Ceilings


のこぎり屋根と登り天井を組み合わせることで生まれる空間の広がりを活かした住宅を計画した。
施主の要望は、家族のつながりを大切にできる木造平屋建て住宅であった。 平屋建てでは中心部への自然採光が課題となることから、東西方向に3列並んだのこぎり屋根に南北に向かって開いた三角形の天窓を合計6か所設けた。 これらの三角窓に向かって登り天井を掛け、天井面を伝う自然光が室内深部まで拡散する構成とした。
夜間照明は、縦長い天井面全体をグラデーショナルに照らすアップライトの間接光で地明かりを取っている。夜には三角窓から漏れる光が周囲を照らす行灯のような家となった。

This house was planned to make use of the expansion of space created by the combination of a saw-tooth roof and sloped ceilings.
The owner's request was a wooden one-story house that could cherish family ties. In a one-story building, natural lighting to the central is a challenge. A total of six triangular skylights facing north and south are installed on the saw-tooth roofs, which are lined up in three rows in the east-west direction. The sloped ceilings are hung toward these triangular windows, channeling the natural light to transmit through the ceiling surface and diffuse into the deep part of the room.
For night lighting, the indirect light of the upright that illuminates the entire vertically long ceiling surface in a gradual manner is used to provide suitable and sufficient lighting. At night, the light leaking from the triangular window transforms the house like a lantern that illuminates the surroundings.
