Custom Add-Ons & Standalone Structures
The sauna may be the heart of your space — but it’s not the only thing we build. We offer accessory building construction for a wide range of uses, whether attached to a sauna or built as a separate structure.
-
Changing rooms and dressing shelters
-
Covered porches, overhangs, and breezeways
-
Gear and firewood storage enclosures
-
Multi-room sauna + lounge combos
-
Detached cabins, bunkhouses, and outbuildings
-
Cold plunge or shower shelters
-
Utility nooks for firewood, tools, or mechanical systems
All buildings are fully framed, insulated (if needed), and finished with the same attention to detail as our sauna builds.
Built for the Land, Not Just the Plan
We work with your property — not against it. Whether you’re building into a slope, nestling something into the woods, or setting up on an open lot, we design each structure around your layout, goals, and the Minnesota climate.
-
Concrete slab or pier block foundations
-
Moisture control and snow-load considerations
-
Exterior and interior material coordination
-
Seamless integration with existing saunas or cabins
-
Venting, drainage, and electrical access options
Already have a sauna? We’ll match materials, dimensions, and roof lines to make your new space feel unified.
