Urban Prism
Urban Prism is a three-story house built in a dense urban area of Tokyo, Japan. The wood structure covers a total floor area of 127.82 square meters on a site of 100.13 square meters. Boundary walls and a gate form a buffer zone that brings light and air into the interior. A courtyard extends the living room outdoors, and adjustable screens control privacy and daylight. Textured fiber cement siding clads the exterior, while oak flooring, steel and glass shape the interior. The sculptural form responds to local height and setback regulations.

Urban Prism House won the Bronze A' Design Award in Architecture, Building and Structure Design in 2025. The A' Architecture, Building and Structure Design Award is a highly prestigious international design recognition program which celebrates excellent design of skyscrapers, museums, residential buildings, commercial complexes, educational institutions, religious structures, infrastructure designs, landscaping projects and more.
