Architect Couple's Vertical Home in Kagurazaka, Tokyo: A Modern Machiya Reimagined





In the bustling urban fabric of Tokyo's Kagurazaka district, a remarkable four-story wooden abode, conceptualized by Takumi Wakui + Riho Wakui Architects, has emerged on a modest 33-square-meter plot. This architectural marvel reimagines the classic Japanese machiya, or townhouse, through a vertical lens, offering a unique dwelling for an architect couple. The project meticulously explores how natural light, ventilation, and a sense of openness can be woven into the dense residential tapestry of Tokyo.
Kagurazaka Vertical Residence: A Fusion of Tradition and Modernity
Nestled in the historic Kagurazaka area of Tokyo, a pioneering four-story residence, envisioned by Takumi Wakui and Riho Wakui Architects, stands as a testament to innovative urban living. Completed on September 1, 2026, this wooden structure occupies a compact 33 sqm site, drawing inspiration from the traditional machiya architecture prevalent since the Edo period. The architects, leveraging their expertise, have crafted a home that not only respects its historical context but also pushes the boundaries of modern design.
The design philosophy centers on verticality, transforming a limited ground footprint into an expansive living experience. Each of the four floors is dedicated to a distinct purpose, with public areas gracefully transitioning to private sanctuaries on the upper levels. This thoughtful arrangement eliminates the need for conventional walls, promoting an uninterrupted flow throughout the house. A series of strategically placed voids visually and spatially connects the various levels, allowing the entire residence to function as a cohesive and dynamic volume.
The external design features large, carefully positioned windows above the living room, offering views of surrounding greenery and ushering in abundant natural light. The top-floor bathroom also benefits from these expansive openings. Unique projecting side walls, extending up to 800 mm from the building's facade, serve a dual purpose: they mitigate harsh western sunlight while expertly capturing the refreshing southwesterly breezes, enhancing environmental control.
Structurally, the building employs a robust truss system along its longitudinal exterior walls, complemented by a central double-wall spine. This innovative construction by Takumi Wakui + Riho Wakui Architects ensures stability while allowing for unparalleled flexibility in floor arrangement and future adaptability. The seamless integration of interior and exterior spaces, along with the interconnectedness of each level through these deliberate openings and voids, creates a living environment that responds intuitively to daily changes in light, airflow, and seasonal conditions, optimizing urban compact living.
This innovative project in Kagurazaka brilliantly showcases how thoughtful architectural design can transform spatial constraints into opportunities for creating luminous, well-ventilated, and adaptable homes, even in the most densely populated urban landscapes. It offers a fresh perspective on vertical living, proving that historical design principles can inspire contemporary, sustainable solutions.
