This house is located in Fukuoka, Japan. Reinforced concrete was used for the basement and wood flame for two of the ground floors. Three floors exist in this layered house, created for different generations of a family to live; the individual spaces are continuous so that the family can have privacy but also feel each other’s presence. A large staircase acts as an apparatus to connect three layers, taking in sunlight and connecting the outside with the house. The stairs are the main traffic area, from which outdoor views can be seen through windows along the wall. These picture windows change depending on your position on the staircase, and create a sense of serenity. The staircase and windows were planed to control the opening to the outside world, cutting the scenery, saving energy, and bringing in requisite sunlight and breezes through the house.
