A guest cabin is a good and easy addition when you need more space at your cottage. You can put up guests in it, store your summer deck furniture over the winter or use it as your summer study while writing your first crime novel.
So a guest cabin is versatile and gives your cottage one or two extra rooms. Read more about the following topics in this article:

The price of a guest cabin
As a kit delivery, a guest cabin costs roughly 3,000-15,000 euros. The cheapest models are about 5 m2 in size and the most expensive about 25 m2. A kit delivery often doesn't include roofing materials, for example, so always read the guest cabin's product details carefully.
As a turnkey delivery, a guest cabin costs an estimated 5,000-20,000 euros, depending on its size and level of equipment.
For example, prices of Ehtasauna guest cabins:
- as a kit delivery 10 m2 guest cabin from 10,400 €
- as a turnkey delivery 10 m2 guest cabin from 13,200 €
Although a guest cabin for your cottage is a fairly affordable purchase – especially given how versatile it is – it is worth remembering that it too brings some extra work and costs in terms of servicing and maintenance.
Why get a guest cabin for your cottage? Ideas for using it!
There are many good reasons to get a guest cabin for your cottage. Often it starts with the need for more space, but there are several good reasons:
- Extra space for guests
- A guest cabin provides extra space and a place to sleep for expected and unexpected guests alike.
- Space for hobbies
- A guest cabin can serve as a study, a hobby room or a studio, for example.
- A sensible investment, too
- A guest cabin can add value to your cottage and make it more desirable if you ever plan to sell it.
- Privacy
- A guest cabin gives your guests privacy and a chance to spend some time of their own in peace, undisturbed.
- Extra storage space
- A guest cabin offers extra storage space for things that don't need to be kept in the main cottage.
- Some peace and quiet of your own
- Sometimes you just want to withdraw a little and dig out that novel that's been waiting to be read – a guest cabin is the perfect place for it.
- Winter storage
- A guest cabin is a good place to keep things that need shelter over the winter, such as garden furniture or hobby equipment

Guest cabin foundations
Don't cut corners with a guest cabin's foundations, as a safe and stable foundation is perhaps the most important starting point for any new building. Poor foundations can shorten the life of your guest cabin.
The right foundation ensures that you also avoid many potential problems caused by subsidence, such as:
- gaps open up in the wall material
- windows and doors stick or don't close properly
- the guest cabin doesn't look good
The right choice of foundation depends on:
- where the guest cabin will be placed
- the soil in the area
Choose the right foundation for your guest cabin like this:
- Soft clay soil -> screw pile foundation
- Bedrock or moraine soil -> traditional pier foundation
- Frost-free ground -> even a very light foundation will do
We have written a detailed guide of our own on foundations – read the ABC of foundations via this link.
Building permits for guest cabins
When getting a guest cabin, always keep local building regulations and permits in mind. Depending on your municipality, you may need a building permit for a guest cabin. Check whether a permit is required from your municipality's building control. A building permit for a guest cabin currently costs an estimated €200-800, depending on the municipality.
In future, however, guest cabins may be built anywhere without a building permit. On 1.3.2023, Parliament passed a new Building Act under which buildings of less than 30 square metres, such as a guest cabin at a cottage, can be built without a building permit from 1.1.2025.
The new Act also states that a building built without a building permit may not be used as a dwelling. One of the criteria for a building intended for residential use is that it has a cooker. So even in future, a guest cabin built without a building permit may not have a kitchen.
