Architecture, Building and Structure Design Black Monolithic Wall Residential House by Nobuaki Miyashita This sculptural black residence was planned in a quiet residential area of Tokyo. The site is narrow at the entrance and elongates towards the back, forming a slender shape. While complying with Japanese architectural regulations, such as shadow regulation on neighboring lands and building height restrictions, the design aims to create dynamic spaces that capitalize on this slender site shape. The approach features a monolithic black wall integrated with the architecture, making the exterior appearance striking, while the cantilevered stairs leading to the entrance enrich the sequence.
