4-layer dwelling unit which is connected by a spiral staircase of 9m.Matsuyama city Ehime, which is the castle town that has developed around the Matsuyama Castle. In this historical town, we designed the collective housing which has impressive façade of glass wall.
This is a small-area collective housing project. Spiral staircase collects the 4-layer dwelling unit. Compact arrangement creates an unusual living experience for the dwellers.
This 4-layer building, which has glass walls in south and north direction, looks like a RC building but is made of wood. When you open the entrance door you can see the spiral steps from entrance to top floor.
↑ 大门关与开的立面，一层无窗户，共四层（其中一层为层高较低的休息室） Facade with doors closed and open, altogether four layers (with a loft space between the first and second floor)
The floor constitutions of the building are a dining area for 1st floor, a tiled bathroom with inner terrace for 2nd floor and a living room for 3rd floor. Loft space is provided between the first and second floor. Solid pine flooring looks very sharp with white space and it makes the space dynamic but also creates calm atmosphere simultaneously.
