I place importance on creating a sense of openness and privacy by shutting the house off from the outside world and allowing natural light and breezes to enter.In addition, since land in Tokyo is generally small, it is very difficult to design while successfully incorporating these contradictory functions. In this project, we carefully considered the height of the view from the surrounding area and planned windows to let in light and wind. And a stairwell was planned in the center of the building so that the light and wind taken in from the outside would reach the entire building.
