深沢の家

The Fukazawa house stands quietly on a plot of land that is reached by climbing a narrow alleyway from the road.
Because the property is what is commonly known as a plot extension or flagpole property, the original building was surrounded by neighboring houses. This meant that although there was a small yard on the south side, the first floor received no direct sunlight, and the rooms had a darkened feel.
Our plan was to convert the existing property into a bright residence adapted to its surrounding environment by adding a new building to the south-facing yard that would incorporate external light through the clearance between the alley and the neighboring houses.
The staircase and colonnade located in the center of the house works to connect the upper and lower floors and convey light, wind, and the presence of others across the various living spaces.
Furthermore, in the living spaces, which are arranged in such a way as to encircle the staircase, we incorporated openings that create an expansive sense of space by providing opportunities to enjoy the surrounding landscape or view the sky in places where it is not blocked by obstructions such as the neighboring houses.
We also placed special-ordered tiles made of light-diffusing material along the walls of the staircase to gently transmit light through the vertical gap between the second and first floors.
These tiles were jointly developed with Guild, located in Tokoname City, Aichi Prefecture, which has long been a center of pottery culture. They are produced using a traditional technique for applying a thin glaze known as chara, and the finished product preserves the texture and softness of the clay itself.
Because each tile is finished to a distinct polish, creating a range of appearances, the arrangement of the tiles is designed to take advantage of the unevenness of the finish and the individuality of the tiles to provide an appealing overall effect of wavering light.
By taking the sunlight and wind that, before the renovation, had only reached the yard, and bringing these things into the house through the colonnade, we were able to incorporate the blank spaces that had previously surrounded the house and recreate the building as a lively residence.

深沢の家は、道路から細い路地状の通路と階段を登った土地にひっそりと建っていました。

俗に言う、敷地延長や旗竿敷地と呼ばれる土地のため、既存建物は隣家に囲まれ、南側に小さな庭があるものの1階までは陽が差し込まないため、室内は暗い印象の家でした。

そこで、周辺の立地環境に適応した明るい住まいへと変換するため、南側の庭部分にあえて建物を増築することにより、路地や隣家との隙間を介して外光を内部に取り込むよう計画しました。

家の中心に設けた階段と吹き抜けは、上下階をつなぎ、各生活スペースに光や風や人の気配を伝える役割をはたします。

また、階段を取り囲むように配置された生活スペースは、それぞれ借景を楽しめる場所や、近くに隣接する隣家などの遮蔽物がなく、空が大きく見える位置に開口部を設けることで、閉塞感のない広がりのある空間としました。

更に階段の縦方向の抜けを利用して2階の光が1階までやわらかく届くよう、手すり壁に光を拡散させる素材として特注のタイルを張りました。

このタイルは、古くからやきもので栄えた、愛知県の常滑市のギルドと共同で開発したもので、急須づくりで用いられる伝統的なチャラ(薄い釉薬をかける)という技法を応用し、土そのものの質感や、やわらかさを残したタイルです。

自分の好みに応じて磨きを加える事で表情が変化するため、仕上がりのムラや個体差が逆に魅力となったり、均一に光沢が出ないことで光の揺らぎがうまれるようにつくられています。

リノベーション前は庭にしか届かなかった光や風も、増築部から吹き抜けを介して、家の中にまわり込み、家の周辺に埋もれていた余白が、暮らしの中に取り込まれた健やかな住まいへと生まれ変わりました。
