Imagine a home where nature isn't just outside your window, but seamlessly woven into its very core. This is the bold vision behind the House in Koganei, a stunning two-story timber residence designed by OFA (OfficeForArchitects) Architectural Design Office, set to be completed in 2025. But here's where it gets intriguing: the heart of this suburban Tokyo home isn't a grand foyer or a luxurious living room—it's a 'tunnel of greenery' that blurs the lines between indoors and out.
Nestled in a quiet neighborhood adjacent to an urban park, this 95-square-meter house is a masterclass in thoughtful design. The project began with a shared dream between the client and lead architect Kiichiro Usami: to create a space where nature isn't just a backdrop but an integral part of daily life. And this is the part most people miss—the meticulous site selection process that ensured the park's lush northern trees could extend their embrace into the home itself.
The result? A generous opening frames the park's landscape, drawing the eye deep into the house and making greenery the principal architectural theme. It’s a design choice that’s both bold and controversial. Is it practical to prioritize nature over traditional interior spaces? Or does this approach redefine what a home can be?
Built with materials from leading manufacturers like LIXIL, Miratap, Toto, and YKKAP, the House in Koganei isn’t just a residence—it’s a statement. It challenges conventional ideas about how we live with nature, inviting us to rethink the boundaries between the built and natural worlds.
Published on December 29, 2025, by ArchDaily (ISSN 0719-8884), this project sparks a conversation that goes beyond architecture. What if every home could bring the outside in, not just as a view, but as a living, breathing part of its identity? We’d love to hear your thoughts—do you see this as the future of residential design, or a beautiful but impractical dream? Let us know in the comments!
