The brief
Fitting a full-height sauna into a tight room in a house still under construction, while getting the vapour barrier, ventilation and heater supply right the first time — none of it is accessible once the lining goes on.
Sweden · 2025
A compact indoor sauna built into a new house: insulated and vapour-sealed shell, aspen lining, hand-finished benching and an electric heater.

Fitting a full-height sauna into a tight room in a house still under construction, while getting the vapour barrier, ventilation and heater supply right the first time — none of it is accessible once the lining goes on.
We framed and insulated the room, ran a foil vapour barrier with every joint and penetration taped, and set inlet and outlet vents so the air actually turns over. Aspen panelling was fitted with movement gaps, benching built in place with hidden fixings, and the heater and shielded lighting wired and certified.
A calm, evenly heated room that stays dry in the structure — handed over commissioned, with the electrical certificate and ventilation set-up documented.

“They stripped the old roof and had the new tiles on before the autumn rain. Weekly photos meant we never once had to chase them. The finish around the chimneys is better than the original.”
“From the first site visit to handover it was the same person, and he answered the phone every time. The house was ready on the date written in the contract — I did not think that still happened.”
“The parquet they laid is the first thing every guest comments on. They protected the rest of the flat, worked cleanly, and the final invoice matched the quote to the euro.”
“Our sauna heats evenly, the benches are solid, and two winters later not a single board has moved. They explained every material choice before we paid for anything.”
“They built the terrace on ground screws without touching the garden, wired the lighting, and were gone in days. It has become the room we use most from May to September.”
“A seven-thousand square metre site cleared, graded and replanted around a working kindergarten, with zero disruption to the children. The most organised contractor we have hired.”
