The kitchen, bathroom, toilet, and other water facilities are concentrated on the first floor, and a compact bedroom and a study are located on the second floor.
The windows were made without metal frames as much as possible, and high-transparency glass measuring up to 10m in length was fixed into the grooves in the same manner as shoji screens.
The gravel and plantings used in the exterior were also arranged from the perspective of the interior to draw the outside environment into the interior.
To make it easier to walk on, the gravel was partially hardened with resin.
Instead of just pouring resin over the gravel, which is usually the case, the resin was applied to the base first and then gravel was laid on it so that the surface wouldn’t become glossy.
In addition, the door handles would have looked abrupt if installed as-is, so an original handle was designed, which hides in the small gap between the door and the wall.
The bathtub is carved into the floor, such that the water surface aligns with the floor, creating the appearance that the tunnel shape is continuous.
The resulting space is less architectural, but rather a project that combines civil engineering concepts with product design details.
