In this Japanese house, accommodating a family of four, a large staircase occupies one third of the space. The home spans the entire east-west axis of the site, occupying the northern half of the plot with the living quarters, leaving space for an open sunny garden to the south.
The elongated staircase in effect bisects the site; glazed on one site, it offers views over surrounding scenery. Within this staircase is houses a spacious engawa-type space overlooking the garden and a study with a vista to the street. On a sunny day the handrail becomes an extended washing-line, and the stair-treads are wide enough to sit and relax upon, while listening to the piano from the lower level.

This seemingly over-scaled staircase is supported by a series of timber columns at 910mm spacing and 16mm steel rods suspended from the ceiling. The timber treads are 50mm thick and the risers are bolted together and placed on a steel girder.
The staircase acts as a mediator of its surrounding environment. Slender yet overlapping columns gently set apart the living spaces from the garden and neighbours; the blanket of sunlight is segmented and diffused by the stairs, handrail, hanging rods and other various elements, eventually reaching the living spaces beyond transformed into mellow and ample light.

The entire face of the bedroom on the upper floor is designed as a recurring series of folding doors, to accommodate future division into smaller childrenโs rooms. On the ground floor, the living room can be opened to the garden, allowing the children to freely run around outside.
Few rooms were actually designed. This approach provides a wide margin for the childrenโs growth and multiple nuances of possible changes. While a vast possibility of change awaits in the future, the existence of this large staircase, anchored to the core of the house, will be instrumental in both adapting and recording the rich dialogue of life.
