About Hikari Tsuzuraori 住宅

光葛折（Hikari Tsuzuraori）是位于日本镰仓长谷寺附近的一栋两层度假住宅。基地为旗杆形地块，四周紧邻民宅，自然采光受到极大限制。设计将结构核心一分为四，错落布置，从而形成数处小庭院，并将日光引入室内。错位的核心筒与交替折叠的屋顶坡面在顶部形成开口，白天引入阳光，夜晚可仰望星空。下层是静谧的日式空间，适于冥想沉思；上层则开敞明亮，承载家庭日常生活。

Unique Properties: It is very close to the Great Buddha and Hase Temple in Kamakura. There is a constant influx of people during the daytime and on weekends, and after the evening, it is enveloped in silence, with not a soul in sight. On the lower floor, where almost no light reaches, we created a Japanese space that makes the most of the gloom, a meditative space where one can escape from the hustle and bustle of the city. The upper floor is designed to be a space of "movement", a place for a happy family and that allows you to feel the ever-changing nature of time.
Dimensions & Packaging: Total floor area is 139.33sqm. Building area is 78.97sqm. Plot area is 154.91sqm. Building scale: 2 storey.

Production Technology: Flag lots are flanked by neighboring homes in close proximity, which makes it difficult for them to receive natural light. In this case, the structure's core has been split into four parts. These four parts are placed unevenly to create a miniature garden and allow natural light to come through.
The four cores are staggered and the roof slope is alternately folded to create an aperture at the top of the building that allows active sunlight to flow through during the day, and a silent starry view at night.
Design Challenge: A variety of opposing themes, including "light" and "dark," "western" and "Japanese," were incorporated into the design to allow those inside to further experience this unique and unusual space as an escape from the hustle and bustle of the city.
Considering its function as a holiday home, privacy was a key concern. The structure is closed off from its surroundings but features an open design in the interior and ceilings.
Inspiration: Near Hasedera Temple, in the ancient city of Kamakura, is where the plans for "Hikari Tsuzuraori" ("Meandering Light") were laid.
This is the client's vacation home, built with an emphasis on creating an out-of-the-ordinary atmosphere.
Project Duration: Design period started in May 2017 and finished in March 2018
. Construction period started in May 2018 and finished in January 2019. Location is Kamakura-city Kanagawa, Japan.
Operation Flow: The client, who lives in Bunkyo-ku, Tokyo, valued spending time with his family and his hobby of surfing on his few days off. He often visited Kamakura for surfing and inevitably came to want a vacation home.
