Architecture, Building and Structure Design Fuma House by Masakatsu Matsuyama Fuma is a three-story house in Fukuoka Prefecture, Japan. The site faces a busy railway to the east, so the first-floor east wall is set back, while the second-floor structure and the third-floor eaves block noise, vibration and street views. Gaps between these elements let natural light and outside ambiance reach the interior. The main living space is on the second floor and works like a single-story home. Reinforced concrete load-bearing walls and unbonded cables support cantilevers of 5.6 meters east and 3.2 meters south. Large glazed openings face the courtyard.
