In the small lot of a quarter where many residential units huddle together arrived a house facing up to the sky. Climb up the tiered floor brightly lit with top lights, and you will reach the courtyard located right in the middle of the house. The rooftop courtyard with sidewalls is only open up to the sky, allowing you to enjoy a complete privacy without concerns over neighbors’ eyes. Although the spaces surrounding the rooftop are all very compact, each floor space is at a different height, providing variety of focuses and use depending on the users’ feeling or need.
