R · torso · C is a minimalist residence located in Tokyo, Japan, designed by Atelier Tekuto. The home is situated on a site area of 711 sq ft for a married couple looking to have exposed concrete for both the exterior and interior of the house. Due to the narrow plot, the home was extended vertically to maximize space with a triangular window opening serving as a skylight. The concrete is composed of a compound mix called “shirasu,” which is volcanic ash found in Southern parts of Japan. The material increases in durability over time while also providing deodorizing qualities.
