Structure Details

This spacious sauna house features a traditional gable roof built on rafters and a central ridge beam at a 23° pitch, rising to a 4.86m (15'11") ridge. The 66.34m² (714 sq ft) footprint provides ample space for a sauna room, changing area, relaxation space, and storage, with 3.19m (10'6") walls for generous headroom. The timber-frame construction ensures proper structural support for high-humidity sauna environments. Large window openings maximize natural light throughout the interior. Structural members are optimized for standard dimensional lumber availability.
