House of Wall Forest 2026: Tokyo Timber Home by IGArchitects

Architecture studio IGArchitects has unveiled the House of Wall Forest in Tokyo, Japan, exploring how the spatial clarity and structural presence typically found in reinforced-concrete buildings can be translated into timber construction. Instead of using timber to form a conventional sequence of rooms, the architects structured the home around a series of structural timber walls.

These walls simultaneously define spatial boundaries, carry the building's load, guide movement, and frame views throughout the interior. The living areas emerge organically between and around the walls, establishing a continuous spatial sequence rather than a collection of enclosed rooms.

The project deliberately imbues timber with a sense of mass and permanence. By expressing the structure clearly, the house achieves a spatial character reminiscent of a reinforced-concrete building while retaining the intrinsic material qualities of wood. Openings and gaps within the walls allow natural light, circulation, and views to filter through the home. Although the architectural framework is robustly defined, the resulting spaces remain open to diverse uses and interpretations.

For the design team at IGArchitects, the House of Wall Forest forms part of an ongoing architectural inquiry into creating durable frameworks for living. Rather than dictating how every space should be used, the architecture establishes a strong spatial order capable of accommodating evolving lifestyles. The project was designed by Masato Igarashi of IGArchitects in Tokyo, Japan.
