Alley House is a minimalist residence located Tokushima, Japan, designed by Container Design. The site is split into two sections, one of which will be built up for the daughter in the future. The exterior is composed of galvanized steel panels and cedar plating. The interior floors consist of white mortar and cedar. The ceiling beams are exposed, allowing the skylight to filter natural light between the columns. Glazed sliding doors provide access to the south-facing garden.
