This project is from married couple who lived in an apartment house in town. This house is a flat building and for a retirement house. The clients hoped to live in a country feeling the change of the seasons at ease. So, I arranged the space in which they enjoyed the change of the seasons and time. The house is suitable for the change of the seasons. I gave the client enough empty space of the ground daringly to enable them to plant tree little by little or to try home garden. There’re grids for blinder and dirt floor in north face toward a road. And the south face is leafy with gardens and there’s highside-light, so the space is rich with the change of the seasons.
