The architecture studio Atelier Tekuto designed an amazing piece of architecture called “R-Torso-C” that is an angular exposed concrete home located in the heart of Tokyo. Working within tight space constraints, the architects cut away at the building’s corners and installed triangular windows to create a unique geometric structure. A floating staircase spirals up through home connecting all the levels, meanwhile the geometric windows punctuate the interiors with a consistent stream of daylight. Additionally, the concrete used throughout the four-story building is completely recyclable and has been mixed with volcanic ash typically found in southern parts of Japan.
