深大寺ガーデン / 田丸雄一＋古谷デザイン建築設計事務所

The project is a semi-public residential development utilizing green production space (planting plots), the idea of a client whose business is environmental and greening projects.
As an antithesis to the unregulated development of residential land that relies on proximity to transportation and commercial facilities and short-term economic efficiency, the project aims to create a connection with the community through active activities and to build a relationship with the town itself. In doing so, he touched on the valuable notion that stakeholders are non-human creatures and the surrounding environment of the house, including greenery, soil, rivers, and wind.
The theme of this project is ” coexistence with the surrounding environment” and “connected living.” The aim is not only to emphasize the environmental performance of the buildings but also to convey a sense of comfort to the town as a group, sounding the alarm bells in the face of possible overdevelopment in the wake of the removal of the green production area designation scheduled for 2022.
The company’s efforts in energy off-grid (solar power, rainwater harvesting, storage batteries), use of locally grown materials, traceability of materials used, and edible gardens have been recognized, and it has been certified platinum for LEED for Homes in the United States. Cool off at the old-fashioned wet veranda, ventilate by a draught, and the sound of the entrance bell. The design was based on the client’s original image of a connected life surrounded by greenery. Using recyclable building materials, the inevitability of the function becomes the design. The client, the designer, and the builder take equal responsibility to create a building that does not diminish asset value. It has made me realize the importance of creating environmental value that architects must think about, not as a ready-made compilation. The roof is flat tile and integrated solar panels. The walls are Kebony wood and aluminum, glass, and stucco, and the floor is wood and stone. It is structured with as little architectural language as possible. The exterior walls are covered with features required by the structure and equipment, such as triple bearing walls, equipment spaces, and insulated air layers. The thick walls create an alcove on the windowsill that extends vertically, creating a breeze soleil effect and a buffer zone between landscape and architecture.
In this building, people gather at Maruta, a wood-fired restaurant, where workshops on making preserved food and other activities foster local cooperation, and this will continue to be an excellent example of development. The unity of these ideas will become a part of the local landscape. (Shunichi Furuya)
