This house is a residence for a couple and a child. The site is located in a newly developed residential area in the southern part of the Okinawa main island, which was reclaimed by landfill. The surrounding area consists of a mix of commercial facilities, industrial parks, residences, schools, sports parks, fishing ports, and other buildings of various uses and scales. To the north of the site is a zoned residential area, and to the south, a commercial area stretches across a large highway. As a result, the north side is relatively quiet throughout the day, but the south side is noisy at times due to heavy traffic. Furthermore, the east and west sides of the site are in close proximity to neighboring houses. In developed areas, houses are densely built and the number of vacant houses is on the increase. While Okinawa has a unique and majestic natural environment, urban areas have this chaotic landscape. In addition, typhoons occur throughout the year, and one must be prepared for disasters. In such an environment, the challenge was to maintain distance from the city and to ensure a comfortable indoor environment. The client requested to live without worrying about the line of sight from the surrounding area, and to let in as much light and wind as possible. The building has a rectangular plan that matches the shape of the site, with public rooms on the first floor connected to the town, and private bedrooms and bathrooms on the second floor. The courtyard and skylight are located in the north-south direction, where light and ventilation can be easily obtained. The courtyard on the north side, which faces the residential area, functions as a buffer zone with a gradual gradation that does not become too closed to the town by making it a continuous space with the approach and the tatami room, which is also a parlor, while taking into consideration the line of sight to the interior. On the other hand, the courtyard on the south side functions as a thick and solid buffer zone between the town and the staircase room, enhancing the livability of the courtyard and the living room. The staircase is also intended to be used as a dimly lit room, so it is a little roomier than a normal staircase to accommodate chairs and other items. By creating a strong and weak buffer zone with the city, we believe we have created a three-dimensional house with wind and light that can accommodate the various activities of daily life in a densely populated residential area. In addition, most of the furniture and fittings were made in my own workshop. I would like to expand the possibilities of craftsmanship that is not dependent on the mainland but is provided within the prefecture.

この住宅は夫婦と子供ひとりが暮らす住宅である。 敷地は、沖縄本島南部の埋め立てにより新たに開発された住宅街に位置する。 周辺は商業施設や工業団地、住宅、学校や運動公園に漁港など、さまざまな用 途やスケールの混在した街区により構成される。敷地の北側には区画整理され た住宅地、南側には大きな幹線道路を挟み商業地域が広がる。そのため、北側 は1日を通して比較的静かだが、南側は交通量が多いため騒がしい時間帯が多 い。さらに、敷地の東側西側は隣家が近接している。開発された地域では住宅 が密集し空き家も増加傾向にある。沖縄には特有の雄大な自然がある一方で、 都市部はこのような混沌とした風景がある。加えて、台風は年間を通して発生 し災害に備えなければいけない。そのような環境において街との距離の取り方 と快適な室内環境の確保が課題となった。 建主からは、周辺からの視線を気にせず暮らしたいこと、できるだけ光と風を 取り入れたいことを要望された。建物は、敷地形状に合わせた長方形の平面と し、街と繋がる1階に居間などのパブリックな居室、2階にプライベート性の強 い寝室と浴室を配置し、隣家の近接する東西方向は壁で閉じ、彩光と通風の取 りやすい南北に中庭やスカイライトを取り、この中庭に面して居室や吹抜けを 配置することで建物全体に風と光の通る構成とした。また、住宅地に面する北 側の中庭は室内への視線に配慮しつつアプローチや応接間でもある畳間と連続 した空間とすることで街に対して閉鎖的になり過ぎない緩やかなグラデーショ ンをもつ緩衝帯として機能する。一方、南側の中庭は、街との間に階段室を挟 むことで分厚く強固な緩衝帯として機能し、中庭と居間の居住性を高めてい る。また、この階段はひとつの薄暗い部屋としての使用も考えているため椅子 などが置けるよう通常の階段より少しゆとりのある空間としている。街との緩 衝帯の強弱をつけることで、密集した住宅地の中で生活の多様な行為を受け止 められる立体的に風と光の通る住宅になったのではないかと思う。 また、今回、家具や建具のほとんどは自分の工房で制作した。本土に頼らず県 内で賄う、ものづくりの可能性を広げていきたい。
