Integrating Nature with Everyday Life: Yosuke Tomiya Designs

Nestled in Hokkaido, Japan, the Morimado House by Yosuke Tomiya redefines residential living by incorporating the surrounding dense forest as an intrinsic part of the home. The house prioritizes nature, with carefully placed windows that frame the evolving scenery each season, making the forest a living element of the household. The innovative approach of the designer ensures that occupants are always connected to the natural world.

The interior features split-level design, promoting interaction through a visually continuous space. Highlights include a double-height living room with a window seat offering mesmerizing forest views. This layout by the architectural firm encourages family communication while presenting versatile spaces for varied moods and activities.

Architectural Harmony and Light in Yosuke Tomiya Designs

Natural light is central to the design of Morimado House. Expansive windows facing the forest, alongside strategically placed high-level openings, flood the home with daylight, casting ever-changing patterns of light and shadow. These elements create a serene atmosphere that harmonizes with the natural surroundings, a hallmark of the studio’s projects.

With a focus on openness, the house balances views of the landscape with privacy from neighboring properties. Constructed with a timber frame and highly insulated envelope, it withstands Hokkaido’s harsh climate. The use of natural wood, white walls, and exposed concrete floors provides a tranquil backdrop that highlights the forest’s seasonal beauty.

Blending Living Spaces with Nature

The architectural vision is further realized with the ‘Forest Window,’ a feature that integrates the changing seasons into daily life. An elegantly arched opening bridges the living area and the forest, linking rooms with a gentle transition, as seen in many of their designs.
