House Uc is a residence designed for a couple in their 30s and their daughter. It is located in the quiet residential area of Tokyo standing on a small and narrow site of irregular shape – a result of the recent trend of dividing property into smaller segments each time it is sold and bought due to inheritance issues and market availability.

The site measures approximately 60 sqm in size: approximately 12 meters deep, 6 meters across where it faces the north road, and 2.7 meters across at the deepest end. The design for House Uc therefore needed to focus on the ideal form of an urban detached house within the constraints of the site itself as well as laws and regulations.
