Lakeside sauna without a building permit – the easiest project ever

Heikki and Carita Jämsänen
Heinola

The Jämsäsen couple experienced their easiest construction project last spring. A lakeside sauna without a building permit is naturally a pleasant thing to implement when bureaucracy is omitted. However, the Jämsäsen's sauna cabin appeared on the lakeside plot fully ready for use – even painted.

When the walk from your front door to the beach sauna is short, it usually means a separate sauna building is located in your garden. But not always.

The Jämsänen couple from Heinola acquired For a 30 square metre sauna building Oman, of a 4000 square meter beachfront plot, a journey measured in hundreds of metres from the home yard. While heating the wood-fired stove in the lakeside sauna, you'll even have time to pop back home for a coffee.

A large pier has also appeared on the shore, with plenty of space for preparing grilled delicacies. After a relaxing evening in the sauna, it's nice to walk home to sleep while the birds sing their concert in the roadside copse.

The Jämsä residents fell for Vasikkasaari – and that was that

Carita and Heikki moved from the capital region to Heinola about ten years ago, having fallen in love with Vasikkasaari, located a few kilometres from the town centre. Wonderful waterfront plots can be found there.

Swedish On Iso, there is a lake covering over 7,000 hectares. It offers not only stunning scenery but also opportunities for diverse boating. The residents of Jämsä can embark on long boat trips from their home harbours.

Carita and Heikki have had several log houses and cabins built on the island. The house is perfectly designed for comfortable living for two adults. For visiting adult children, a lakeside cabin has been acquired where they can holiday in peace and quiet.

Carita is a passionate gardener who has made every house's garden flourish. Her latest home was completed this year on an absolutely stunning, rocky waterfront plot.

Almost next door, a 4000-square-metre plot of land was for sale. After buying it, the Jämsäs determined that a summer cottage located close to home would be nice. One should often enjoy the steam from the wood-burning sauna., when a cottage trip works without a car. On foot.

This is how a ready-to-use beach sauna was realised without a building permit

From dreams to reality. But what does a ready-to-use beach sauna without a building permit mean?

For Carita and Heikki it was 30-square-metre sauna cabin, that was brought to the site fully complete from the factory. Under the regulations that came into force at the beginning of 2025, the commencement of any building measuring up to 30 square metres no longer requires a building permit – as long as it is not a building intended for permanent residential use.

The precise size of the sauna cabin 30 chosen by Jämsä is 29.6 square metres. The walls are 95 mm laminated logs. In Carita and Heikki's cabin, there is an open shelter between the sauna and the living room, intended for storing firewood. It is also possible to build a washroom, bedroom, or kitchen in the intermediate space.

For fittings, Ehta offers a wide range of options, including ready-made kitchens and bathrooms.
