Design & Build
From Concept to Built Reality
We turn design ideas into beautifully built wellness spaces. Every project starts with a respect for simplicity, natural materials, and how a space should feel when you step inside it.
We work with carefully selected premium materials, chosen not just for how they look, but for how they behave over time, especially in heat, steam, and changing conditions.
Combined with a mix of modern manufacturing techniques and traditional woodworking, from precision CNC detailing to handcrafted joinery, we create saunas and other products that feel solid, refined, and naturally balanced.
The result is a product that feels personal, considered, and made to last for years of daily use.

FAQ
We use ThermoWood® (thermally modified pine) for the sauna exterior, while benches are made from aspen and alder. Thermally treated wood is ideal for saunas as it’s resistant to water and humidity, doesn’t swell or shrink, won’t warp or twist like untreated wood, and doesn’t leak resin.
