Summit Interlock Cabin is a temporary alpine shelter designed for high-altitude environments where conventional construction often causes permanent damage to fragile mountain landscapes. Traditional mountain huts rely on heavy foundations, mechanical fasteners, and long construction periods, permanently altering terrain and making removal difficult. This project explores how architecture can exist temporarily in extreme natural environments without leaving long-term environmental impact.

The project proposes a reversible architectural system that can be transported, assembled, disassembled, and relocated with minimal disturbance to the site. All building components are prefabricated and designed to fit into two standard shipping containers, allowing helicopter transport to remote mountain areas where road access is not available. The structure can be assembled within one day by a small team, significantly reducing construction time and site intervention.

The architectural concept is generated from the roof geometry. The sloped roof is designed as a series of steps, functioning both as enclosure and as a communal viewing terrace where climbers can rest and observe the surrounding mountains. At the point where the extended roof touches the ground, a sheltered outdoor space is formed, functioning as the entrance and a campfire gathering area. This space becomes the social center of the shelter, connecting the building with the landscape.

Inside the cabin, sleeping areas are designed as climbable platforms integrated into the stepped roof structure. These platforms also function as structural supports, merging furniture, structure, and architecture into one integrated system and maximizing spatial efficiency within a small footprint.

A key technical feature of the project is the fully interlocking timber structural system based on traditional mortise-and-tenon joinery. The building is assembled without nails, screws, or permanent fasteners. Each timber component is digitally fabricated and precisely cut so that structural members lock into each other to form a stable frame. This dry assembly system allows the building to be dismantled without material damage and reassembled in another location. The cabin is elevated on a timber platform instead of permanent foundations, allowing the site to recover after relocation.

Summit Interlock Cabin therefore represents a prototype for reversible architecture in fragile environments, combining prefabrication, modular logistics, traditional joinery, and sustainable site strategies into a new approach for temporary mountain infrastructure.
