This is an office and residence built in the center of Fukuoka city. A frosted glass screen was installed on the façade to protect privacy and soundproofing, as it faces a very busy road. A bright indoor environment is ensured by providing an opening on the entire east side, which is the only daylighting surface, and a terrace and top light on the top floor. The structure is expressed as exposed concrete on each floor, but the material and color of the finish that fills the space are changed according to each space. While the façade and structure give a strong image of penetrating the entire building, the interior creates a varied atmosphere.
