There is a scene where wheat grows and bread is baked every morning in a wood-fired kiln. We would like to provide a space where you can get to know the production process through Campagne (German country bread), experience how to eat at a cafe, and propose eating habits. We also want to include in the architectural plan to open the building in the area so that it can be used by the local people as a place where the threshold is low and calm so that it can be used as a part of life. I think it will be a beloved place if people from afar can take a break by cycling, add it during the dog walking course, or take a short break to pick up and drop off at the nursery school. As a specific example of opening to the area, it is possible to use it as a semi-outdoor store as a face-to-face coffee stand, and use it easily or at the eaves without entering the store. It's about providing a space where you can sit on a bench and use coffee and bread as if you were on a detour, rather than having a meal like a restaurant.

Rooftop House | Kiyose Three-Generation House with Cat Concept and Spatial Composition Located in Kiyose, Tokyo, this residence for a three-generation household plus a cat integrates functionality, accessibility, and harmony with the local environment. Situated in a residential neighborhood a 15-minute walk from Seibu Ikebukuro Line’s Kiyose Station, the site is surrounded by the scenic charm of Kiyose’s signature carrot fields. In the context of Tokyo’s limited land availability, the design maximizes the auspicious fan-shaped plot, creating a wheelchair-accessible home that balances family togetherness with individual independence. The rooftop offers a borrowed view of a majestic, over 100-year-old cherry tree—a local landmark. Accessibility Designed for wheelchair users, with a sloped entry leading directly to the first-floor dining space. Kitchen, bathroom, toilet, and bedrooms are all on the same floor, ensuring a barrier-free environment for all generations. Multi-Generational Harmony The first floor serves as a shared space for all three generations, fostering family bonds. The second floor includes bedrooms and a living area for the younger generation, maintaining a balance between togetherness and privacy. Site-Specific Design The building’s fan-shaped plan mirrors the plot’s auspicious shape, maximizing the building coverage ratio. Efficiently utilizes Tokyo’s scarce and costly land, creating an expansive yet practical spatial layout. Century-Old Cherry Tree The rooftop, accessible from the second-floor living area, is an ideal spot for cherry blossom viewing in spring. Incorporates the borrowed landscape of a 100-year-old cherry tree across the street, embracing a regional treasure. Pet-Friendly Living Designed with the household’s cat in mind, ensuring safe and comfortable spaces for the pet. Creates an environment where the entire family, including the cat, can coexist harmoniously.
