The open mouth of this steel-clad house in Fukuoka, Japan, by architects Case-Real reveals its interior to anyone strolling by.

Red and grey galvanised steel envelops the exterior of the House in Saitozaki, which is single-storey on side but has two storeys on the other.

A pitched roof with exposed eaves shelters living and dining rooms on the single-storey side, while utility rooms are located opposite beneath three first-floor bedrooms.

Storage areas inside the house are built into the walls, while the floors are covered with dark wood panels.

Other recent projects by Case-Real include a dorm with a curvy timber deck and a boutique with concave walls - see them both and more here.
