4.7/5

Modern cabin

A spacious, modern and versatile cabin for the discerning user. The size of the cabin allows for a separate living room and bedroom, dividing the space into smaller areas to suit the users' needs, and everything else you need for comfortable cabin life.

Cabin 30 works wonderfully as a high-quality summer cottage for a single family or as a versatile extra space for various leisure needs. The living area can accommodate a larger group of friends for an evening gathering, and the separate sleeping nooks can comfortably host multiple generations.

Cabin 30 can be built without a permit

The Building Act was reformed at the start of 2025, and outbuildings under 30 square metres no longer require a permit. Read more from our article.

If you need a building permit, we will provide the necessary drawings and help you with the permit application. You can also order a building permit service, in which case we will apply for the permit on your behalf.

Dealing with Ehta has been easy and flexible from the very beginning. We first contacted Ehta in July 2025, when we received a preliminary plan for our cottage. However, the idea was left to simmer and we continued planning about half a year later. The project has therefore progressed at our own pace, which has been particularly important to us. We refined the plan to our liking several times with Johanna, and when we finally got it finished, the rest of the project progressed very quickly and smoothly. At this stage, our contact person was Mirjami, and she kindly answered our questions and kept us up to date on the various stages of the project. Our wishes were still wonderfully taken into account, and we were able to make last-minute changes to, for example, the electrical plan.The delivery time estimate given at the beginning of the project was spot on. We had prepared the foundations in accordance with Ehta's good instructions. On the day of delivery, our driveway turned out to be a little too cramped for the transport company, so this is something to bear in mind when planning the lorry's route into the yard. It is therefore a good idea to add some extra leeway to the given dimensions. Despite everything, the skilled personnel got the cottage into place without any problems and carried out the final installations.All in all, the entire customer experience with Ehta has been very good, worthy of five stars. Now we have the loft cabin of our dreams and space for the whole family! Special thanks to Johanna and Mirjami, who have patiently always taken our suggested changes into account and realistically told us if something wasn't possible. Thanks also to everyone at the factory who has been making this dream of ours a reality! The quality of the workmanship is brilliant!

On the plus side: high-quality materials, good instructions, the scope of delivery, and when problems came up we quickly got good advice over the phone. On the minus side: black marks on the logs, and the door handles were missing from the delivery. the handing of the gable window on one side should have been a mirror image of the other so that it would open after the fireplace was installed.

The whole process worked well; we always got answers to our questions. The changes we wanted were received positively and we got better, more workable suggestions from the professionals. At no point, from the first negotiations to the end result, has there been anything to complain about. All the agreed changes were made. The delivery went ahead on the agreed day and we got a brand-new cabin on our plot. Even after the delivery, we've had answers to some tricky questions. We're happy with our cabin.
