The black cedar by Naf Architect & Design – It is a creation of architect Tetsuya Nakazono, of Naf Architect & Design, and is in Hiroshima (Japan). The house occupies a total area of 172.55 meters square and is divided into three different plants. In addition, the exterior color was chosen so that the building would not stand out too much as it is in a traditional Japanese neighborhood, if not differentiate enough already.
On the first floor there is a small hall, a large bedroom, living room and a bath mat. The second floor is the one that connects the two parts of the house via a spiral staircase surrounded by glass cylinder that isolates it from the outside, but includes a door to go out and seize the opportunity as a terrace.
