House M, a 30 sqm home in Tokyo’s Setagaya Ward, shows how a compact footprint can still feel spacious through a series of deliberate design moves.
Vertical layout reshapes everyday flow
Architect Takehiko Suzuki built the house on a narrow site that sits beside an active railway line. The layout revolves around a central pillar that supports a spiral staircase, turning the vertical axis into a series of functional zones. Each level—genkan, dining, sleeping loft—connects through subtle shifts in ceiling height, natural light, and material palette, allowing circulation to double as living space.
At the entrance, the first stair treads widen and remain open underneath. Beneath the steps, shoe storage fits neatly, while the tread surface doubles as a bench for putting on or taking off footwear. By integrating seating and storage into the staircase, the entry area becomes an active part of the home rather than a simple passage.
The sleeping loft hovers just enough above the floor to reveal a storage cavity. Lifting the platform creates room for suitcases, seasonal clothing, and other items, all accessed by lifting floor panels. The result is a bedroom that appears light and uncluttered, yet retains ample capacity for belongings.
Multi‑purpose furniture blurs boundaries
Between the dining area and the stair sits a waist‑high cabinet that can be approached from either side. Glass sliding doors on both facades keep sightlines open and let daylight filter through, preventing the unit from acting as a solid barrier. The piece stores everyday objects while contributing to the sense of openness in the floor plan.
In the living room, a built‑in sofa sits slightly back from the stair edge. Its recessed base reduces visual bulk, granting the room a bit more breathing space despite a tight footprint. Long enough to accommodate overnight guests, the sofa serves both as daily seating and a temporary bed.

A simple metal rail runs along the balcony’s edge, providing a hanging spot for towels or laundry without consuming valuable outdoor area. Though modest, the rail exemplifies the project’s broader logic: even peripheral zones are treated with the same attention to function and visual lightness.
These interventions illustrate how circulation, storage, and structure can share roles. Stair treads expand then contract; light shifts as one moves upward; and each element performs more than one function.
For residents, the design means daily routines become smoother. The integrated shoe bench at the threshold eliminates the need for a separate entry bench, while the loft’s hidden storage reduces clutter in living zones. The double‑sided cabinet allows kitchen tasks to flow uninterrupted, and the recessed sofa offers a flexible spot for both relaxation and guests. Overall, the house demonstrates that thoughtful spatial planning can offset the challenges of a diminutive lot.
