Nobuya and Ayaka Kojima, the architects behind Kojima Architectural Design Office, are pioneering a fresh perspective on home creation through their condominium renovation brand, “One Mat, Ten Spaces.” Based in both Tokyo and Shanghai, the couple combines Japanese aesthetics with modern design, bringing the best of traditional Japanese housing into contemporary renovation. Through self-branding, they aim to make architecture more accessible to residents, presenting architects as approachable, trusted partners in home design.
Commitment to Japanese Craftsmanship, Materials, and Harmonizing with Light: The Vision Behind “One Mat, Ten Spaces”
Upon opening the door, visitors are greeted by a serene Japanese-style room, a stone-finished floor entryway, and a kitchen with an open view—this is the Kojimas’ home and the first project that embodies the “One Mat, Ten Spaces” concept. Launched in 2021, this brand represents a groundbreaking step for architects managing their own brand. Through it, the Kojimas strive to convey the home-building process transparently, providing reassurance and fostering a sense of connection with residents.
The name “One Mat, Ten Spaces” stems from the idea that even a single space can offer ten different areas of comfort. The brand defies conventional layouts by using sliding screens and partitions to flexibly define spaces as needed, blending Japanese elements while adapting to contemporary lifestyles. The entire space is designed to foster family connection, reflecting a unique approach to creating shared spaces.
Their choice of materials focuses on natural ones that resonate with Japan’s climate and culture, such as diatomaceous earth, Japanese paper, and natural wood. These materials bring warmth through their handmade textures and enhance the flow of soft light within the living space. Traditional Japanese elements like sliding doors, screens, and transom windows are given a modern edge, creating a space that is both timeless and sophisticated.
“One Mat, Ten Spaces” also insists on using materials and equipment tested in their own home before recommending them to clients. “Branding prevents deviation from the core concept and enables a clearer vision for the residents,” Ayaka Kojima explains.
A New Shape of Condominium Renovation: The Future of “One Mat, Ten Spaces”
In its four years since establishment, “One Mat, Ten Spaces” has completed nine projects, continuing to provide a new perspective on Japanese home creation while advancing projects in urban areas. “Branding in renovation is not just about efficiency; it brings transparency and connection to the home-building process,” says Nobuya Kojima. As a fresh approach to condominium renovation, “One Mat, Ten Spaces” is anticipated to offer new value to many residents.
