This house is located in a heavily trafficked road on the north side.We thought that is important to be connected the scene of life continuously while moved up and down about this project. We placed each space like spiral around the stairs. So that It is possible to move around each space without feeling the difficulty moving up and down.The first floor is garage and work spaces, the second floor is a living and dining space on sunny south side, the third floor is a private room and master bedroom. And we have placed closed spaces (such as toilet ,storage, sanitary) on the north side. So we were able to get a quiet and sunny living environment.
