Prefab Cabin on a Rock

Thornton, New Hampshire


This 900 square foot prefab cabin is a weekend residence for a couple and their two young children. The design is by Boston-based firm I-Kanda Architects, engineered by Fire Tower Engineering, and built by Bensonwood. The modern prefab cabin is perched precariously over a steep granite ledge allowing for dramatic views of the valley around the Thornton, New Hampshire area of the White Mountains. Instead of removing the granite ledge for a level building area, the uneven topography of the bedrock was embraced by hand pouring nine concrete footings for a prefab timber frame. Minimal trees were cleared for the project, preserving the natural landscape and surrounding views maximized by placing a 24-foot-wide sliding glass wall designed by Architectural Openings. The challenges associated with the building site were able to be solved by exceptional design, engineering, and building with prefab components.
