Sophisticated manufacturing with quality

KOYA Manufaktur's mission is for people to experience absolute quality when using our systems. The design and architecture of our products should arouse fascination and admiration for the purist forms and details and evoke a sense of well-being and relaxation when used indoors. We are particularly proud of the Sauna Cubes and Garden House Cubes, which owe their design inspiration to a classic cube. "By definition, the perfect cube is equilateral, has smooth, uniform surfaces and is slightly rounded at the corners." Our development team, consisting of architects, designers and engineers, has created a minimalist design with maximum functionality and sophisticated quality with the KOYA garden shed. Many hours of work go into the production of a KOYA garden or sauna house. Starting with individual planning, our team enthusiastically takes on almost every challenge. KOYA offers a carefully selected range of products for the individual design and furnishing of a modern garden cube. In our manufactory, we produce garden houses, outdoor saunas and garden offices with dedication and passion. Out of love for the product, we process the highest quality metal and wood materials with great craftsmanship, making every project a special experience.
