led by architect tsuyoshi shindo, japanese office be fun design has completed a four dwelling structure named the ‘spiral house’, in the city of matsuyama. each module is arranged with the same layout throughout four floors, which are connected by a spiral staircase placed at the front of the unit. the front façade is composed of large windows on the three upper levels, and exterior-mounted sliding doors at grade. the transparent elevation reveals the characteristic circulation element, as well as the narrow and deep spatial conditions of each apartment.

the layout places the kitchen and dining area on the ground level, with a bedroom loft just above. the second floor contains each dwelling’s bathroom, while the top story is open for flexible living space and features a large window facing the south. the material palette includes predominantly white surfaces, complemented by solid pine flooring.
