norwegian studio lundhagem has completed ‘cabin knapphullet in norway’, replacing two previously existing structures. the building is accessible from a small path cutting through a heavily vegetated area from the main house, taking advantage of large boulders that form a naturally protected area. the design features a unique precast roof that extends from the side of the rock and angles down to meet the ground plane to double as a staircase leading to a rooftop deck. beneath the free-standing canopy two exterior storefront walls make the structure almost transparent across the landscape. the small footprint minimizes its impact on site, and instead enjoys three levels that contain a small living area, a suspended bed, and bathroom overlooking the sea.

the natural formations surrounding the cabin are invited into the interior design, allowing the natural rock face to serve as a wall with glass and wood features that relate to the forest environment. inversely, the interior concrete bench that lines one side of the floor plan extends outdoors to frame an entry patio and fire pit that can be enjoyed in the summer months. the ceiling features interwoven oak strips that screen the joint lines in the roof. the timber ceiling offsets the concrete and rock surfaces and brings a sense of warmth to the light flooded space.
