Student architects design ship-hull-inspired community sauna in Norway
Reclaimed timber structure creates sheltered public space along fishing harbor
1Harbor-inspired architectural concept
The 40-meter-long Skroget sauna mimics a ship's hull through its skeletal timber frame, designed by NTNU architecture students. Positioned along Norway's fishing capital harbor, the structure integrates public seating, a sauna, and a fire pit terrace. Its elongated form responds to the coastal site by creating distinct sheltered and exposed zones. The name 'Skroget' directly references Norwegian nautical terminology for hull construction.
2Collaborative design process
Fifteen architecture students developed the project through an iterative design process, beginning with individual proposals that were narrowed to three final concepts. The team prioritized creating a connection between sauna users and the cold harbor waters, envisioning future bathing opportunities. Their final design features nineteen angled timber portals that form a sloping roof, providing wind protection while maintaining views.
3Sustainable material strategy
Nearly all structural components utilize reclaimed timber from a demolished municipal building, minimizing new material use. Contrasting with this approach, the 15-square-meter sauna interior features new pale birch wood, while exterior benches echo the angular framing. The project demonstrates how student-led initiatives can implement circular economy principles in public architecture.
4Site-specific spatial organization
The linear layout creates a continuous hallway connecting public and private zones without dead ends. Visitors progress from the western fire pit through changing rooms to the eastern sauna, with all spaces oriented to maximize southern sun exposure. Angled timber walls shield the landside areas from prevailing winds while framing harbor views from the waterside.
5Community-focused amenities
Beyond the sauna, the project incorporates multipurpose public spaces including sheltered seating areas and a fire pit terrace overlooking rocky shoreline. Furniture designs mirror the building's angular language through sloping seats and backrests. This approach transforms a utilitarian structure into a social hub that engages both locals and visitors with the harbor environment.
6Climate-responsive design features
The structure addresses Båtsfjord's harsh coastal conditions through its wind-sheltering southern orientation and durable reclaimed materials. Nineteen timber portals create graduated protection, with more exposure toward the water and increased shelter inland. This passive design strategy extends seasonal usability while reducing mechanical heating requirements for the sauna complex.
7Educational design-build model
As part of NTNU's Design in Context course, the project provided hands-on experience in community-engaged architecture. Students managed all phases from conceptual design through material sourcing and construction. The municipal partnership for material reuse demonstrates how academic projects can deliver tangible public benefits while testing innovative construction methods.
8Regional sauna design context
Skroget joins a growing collection of innovative Norwegian saunas, including Rabagast Studio's floating lake sauna. The project distinguishes itself through its harbor integration and material reuse narrative. Like Finland's Puusauna with its tree trunk colonnade, it demonstrates how regional vernacular traditions can inspire contemporary thermal architecture with strong place identity.
