It is a villa built in the mountains of Kirishima famous as a summer resort with rich natural hot springs. A spectacular view over Kinko Bay and Sakurajima spreads beyond the south slope. In order to make use of the superb view, we adopted a structure in which the approach level floats as it is against the slope in order to make the viewpoint higher than the grounding property. Also, in order to preserve the natural topography, I widened the jumping part and reduced the ground contacting surface. Horizontal line floating in the vertical line of trees is the essential point of design, finish the roof of the horizontal plane and the floor board white, and the vertical elements such as pillars are made to release concrete with texture. It is an image that the floor board and the wall board protruded from the wall of the concrete piercing the slope. From the interior, make the corner pillar small round round pillar and make the opening continuous at the corner, cut the landscape horizontally with a deep strike and a balcony that jumps 4 meters and protrudes into the landscape like the moonlight stand.
