Frequently asked questions
Do I need a permit for a garden studio or sauna?
It depends on the country and the size. Small detached buildings are often exempt or need only a simple declaration, while anything used as living space usually needs planning permission. Check with your municipality before ordering.
How much does a garden sauna or studio cost?
Add-ons on this page with a published price start at €2,601; the median is €24,900.
Can I order an add-on with my prefab home?
Yes. Several house manufacturers also build saunas, garden studios and annexes, and delivering them together saves on transport and installation. Ask for both in the same quote.
