prewood: a compact timber insertion in tokyo
In Tokyo, VUILD completes prewood, a compact timber building that occupies a narrow urban gap with a precise, modular approach. Set within a dense streetscape, the project fits between neighboring structures with a quiet confidence, its vertical cedar facade introducing a distinct texture while maintaining the rhythm of the street.
The exterior reads as a stacked composition of wooden panels, articulated through subtle shifts in depth and angled cuts. Openings are placed with restraint, offering glimpses of activity inside while preserving privacy along the tight frontage. The material remains untreated, allowing the cedar to weather gradually, its surface expected to shift in tone over time in response to the city’s climate.

vuild designs modules for reuse
At the core of prewood is a construction system developed by the team at VUILD that treats the building as a set of discrete wooden modules. Each unit is designed for disassembly, allowing the structure to be taken apart and relocated in the future. This approach extends the lifespan of the material beyond a single site, aligning the design with a broader consideration of resource cycles.
The modules are stacked vertically, forming a compact volume that maximizes usable floor area within the constraints of the plot. Digital modeling tools were used to define thousands of screw positions, translating directly into fabrication data. On site, assembly proceeded with a high level of precision, supported by 3D-printed guides that ensured consistent alignment across each connection.

interior sequencing and spatial compression
Inside, prewood organizes its program through a series of split levels that expand the perception of space within a limited footprint. Service elements are concentrated toward the front, freeing the remaining areas for seating and circulation. The vertical movement between levels introduces variation in ceiling height and perspective, shaping a sequence that feels continuous yet differentiated.
The interior palette is restrained, with plaster walls and exposed timber surfaces defining the atmosphere. Light enters through carefully positioned openings, grazing the surfaces and emphasizing the grain of the wood. In the upper levels, a semi-private zone supports small gatherings, while a rooftop terrace offers a moment of openness within the surrounding density.

construction logic and urban timber application
The building’s structural system responds directly to the constraints of its site. With limited space for scaffolding, the modular components enabled rapid assembly, completing the primary structure within a short timeframe. The process reduced reliance on specialized carpentry, instead relying on a coordinated system that could be executed with standard construction labor.
Material choices also address regulatory and environmental considerations. Located within a fire prevention district, prewood integrates cross-laminated timber ceilings designed to perform under fire exposure. The use of cedar panels, combined with ventilation gaps and protected end grains, supports durability while maintaining the material’s natural finish. Through this approach, VUILD positions prewood as a working example of urban timber construction adapted to dense city conditions.
