Perched on a rocky landscape, Oslo-based Manthey Kula’s summer house in Bohuslän, Sweden, is characterised by its light touch.

In order not to destroy any part of the natural site the holiday house is designed as a bridge spanning 29 meters from one bedrock plateau to another. The load-bearing structure consists of two laminated timber arches spanning across boulders left by the glacier more than 12 000 years ago.

The arches were transported to the site by helicopter and bolted to steel brackets carefully placed and drilled into the granite. Two delicate steel trusses connect the building to the terrain bracing it against the heavy coastal winds.
