This home in a high-density residential district in Tokyo’s suburbs was commissioned by a designer at a large real estate company. The roof and exterior walls are constructed from metallic grey Galvalume which both forms a structural skin and protects the privacy of the residents by shielding the first floor from visibility from the street. A large opening in the roof brings in abundant natural light and makes the compact space feel more expansive.Thanks to a courtyard-like layout that ensures privacy and a peaceful mood, it is hard to believe the street is just on the other side of the wall.
