SAUNA

Configure your own backyard sauna -- fully insulated, built the way a sauna actually needs to be built. Unlike a simple garden shed, this configurator models the complete insulated envelope: mineral wool in the walls, ceiling and floor, a vapour barrier, a cold-ventilated roof, and traditional tongue-and-groove interior lining sized to real timber sections. Drag the footprint, set the roof shape and pitch, place your heater and benches, and the 3D model -- and its priced parts list -- update as you go.

• Fully insulated wall, ceiling, and floor build-up -- wool, vapour barrier, and battens, layer by layer
• Traditional tongue-and-groove interior lining, cold-ventilated roof construction
• Mono-pitch or gable roof, with automatic gutters and downpipes sized to the roof area
• Heater and bench layout sized automatically to the room
• Optional terrace / deck, with a cladding colour scheme that matches the sauna
• Deep roof overhangs get their own knee-braced support posts
• Step-by-step assembly animation, from the ground screws to the gutters
• Instant, itemised Bill of Quantities with real supplier part numbers
