White cave


The house is built on a hill overlooking the city. The site left over from the development has an irregular shape , and there is a 2 meter difference in elevation within the site. The north side of the site is bordered by several neighboring lots with different elevations, and the west and south sides are adjoined by trees surrounding the ancient tomb park across the path, while the east side has a view of the city.

As I walked along the path that runs alongside the site, I was fascinated by the way the landscape changed. By placing the building alongside the path and across the 2 meter difference in elevation, we tried to bring this charm into the interior. The layout of each room was decided by following the path.

The complex context of around the site and the irregular shape of the site, we wanted to bring this diversity to the building. The plan is amplified in the short side direction by 300mm at intervals of 2,700mm against the long side direction. I tried to create enough turbulence in one operation to not confuse the whole. A slight change in the angle of the wall will change the way people move and the impression of the space. The way the landscape looks, the distance from the outside, and the relationship with the surrounding environment, such as the way light enters the building, have all become more complex.

The exterior walls and roof are left with a rough concrete finish, and the openings are made to show the thickness of the concrete, as if they were gouged out of a block. I wanted to create a continuity between the building and the characteristics of this place, such as the surrounding concrete retaining walls, the tranquility of the ancient tomb park, and the dense trees. With the slight amplitude of the volume, I thought about how something as hard and static as concrete responds to the environment as a place for living.
