Architectural design for timber and custom homes in Sapporo, Asahikawa, and across Hokkaido

TIMBER FRAME

Timber frame homes designed to last for generations

Without relying on nails or diagonal bracing to define the space, timber frame construction expresses the beauty of exposed joinery itself. By combining traditional framing logic, carefully selected materials, and exterior insulation, we create homes in Japan that balance architectural character and modern performance.

Construction: exposed joinery that preserves visual beauty

Timber frame construction originated in ancient Europe and was later restored and refined in North America. Unlike typical post-and-beam systems that depend heavily on concealed hardware or wall bracing, this method expresses the structure itself as part of the architectural design, creating a distinctive interior with visible timber craftsmanship. :contentReference[oaicite:2]{index=2}

Material: the strength and elegance of oak

Our timber frame homes use oak, selected for its high strength and long-term durability. In addition to structural performance, oak is valued for its beautiful grain and rich appearance, making it a premium wood long associated with fine furniture, flooring, and even wine barrels. :contentReference[oaicite:3]{index=3}

Performance: exterior insulation suited to cold climates

We use exterior EPS insulation to improve thermal efficiency and protect the structural frame from outdoor temperature stress. This approach performs especially well in colder regions such as Hokkaido, helping the home warm up efficiently in winter while also supporting cooling efficiency in summer. :contentReference[oaicite:4]{index=4}

Philosophy: structure, material, and protection working together

High-strength oak, traditional braced timber framing, and exterior insulation that helps shield the frame from the elements—these three ideas work together to support a long-life housing concept inspired by structures built to endure for generations. :contentReference[oaicite:5]{index=5}

Planning Point

Insulation, airtightness, and detailing must be resolved early

In timber frame design, the balance between exposed structural beauty and building performance is decided early in the planning stage. We place strong emphasis on details that allow thermal performance, airtightness, and clean architectural expression to work together rather than compete. :contentReference[oaicite:6]{index=6}
