熱海の茶房
Tea house in Atami

Atami / Tea house
We were approached by a retired couple to design a tea house, which is a small building of about 60 square meters. The site is located a short walk from Kinomiya Shrine, up a steep slope. The site itself was carved out of this slope, which made for an environment that felt rather violent. However, there is a slight gradient that extends toward the depth of the site, and the pleasant sound of a babbling brook can be heard all along the premises. We imagined architecture that would protect customers from such a violent environment so they could fully savor the small charms that can be seen and heard hidden away from the surroundings.
In the longitudinal direction of the long and narrow site, there is a concrete retaining wall to protect against landslides from the top of the cliff and a deep foundation which has been lowered from the bottom of the cliff to the line of the angle of repose, in compliance with regulations for building near cliffs. The light wooden frames were hung on the L-shaped reinforced concrete structure lifted from the ground. Reinforced concrete construction protects customers from severe environments, and the wooden frame softly wraps the person. We felt this to be the most suitable structure for this site. In addition, since the horizontal force is borne by the concrete structure, it was not necessary to install any structural reinforcements in the upper wooden portion that would obstruct the scenery.
In a space where the ceiling height is kept to 2,100 mm, customers can rest themselves on a bench integrated with the concrete structure and fully enjoy a view of the trees spreading beyond the eaves and the sound of the babbling stream.

細長い敷地の長手方向に崖条例のため、崖上からの土砂崩れに対してコンクリート擁壁、一方崖下からからは安息角の下までの基礎を下げた深基礎になっている。この地面から持ち上げられたL字型のRC造の上に、軽やかな木造の架構をかけた。RC造は客を激しい環境から守り、木架構は柔らかく人包みこむ。この敷地において、最適な構造形式だと考えた。また水平力はRC造が担うので、上部の木造部分には風景の邪魔になるような構造材を設けずに済んだ。天井高さを2,100と低く抑えられた空間で、客はRC造と一体になったベンチに体を預け、軒の先に広がる樹木と小川のせせらぎだけを楽しむことができる。
