More information

  • Supplied as prefabricated parts for easy assembly
  • Use Polhus contractors for installation assistance

Mariedal's one of our most popular prefabricated cabins. Downstairs, there's a large, spacious cabin with a main room and a bathroom, and above the bathroom, you'll find a cosy sleeping loft. The wide, slatted glass doors make the house light and airy. The house meets the Swedish Housing Authority's requirements for permanent housing regarding energy management, ceiling height and adaptation for the disabled.

Mariedal works well as a holiday home or as a luxurious extra room for a home office or a hobby room for activities that require a bit more space.

When you've decided where you want to put the cabin, prepare the foundation by levelling the ground, casting or digging plinths and gravelling a ground surface larger than the building according to our instructions. Because the cabin's already manufactured and in stock, we offer fast delivery.

The walls are delivered as panel that you erect and assemble on site. The floor joists and roof parts are all pre-cut to the correct lengths, so you need only assemble your cabin according to the manual. If you have any questions during the installation, you're always welcome to call customer service and talk to a cabin assembly expert.

If you don't want to assemble the house yourself, you can also order our assembly package. Our experienced Polhus contractors'll come out and assemble the cabin on your plot.

When the cabin's fully assembled, all that remains are the final touches, such as painting the outside, laying roofing, furnishing the inside with wooden panels or anything else you feel is necessary. We offer accessory packages such as roof cladding packages, insulation packages and interior cladding packages.

 When ordering, you have the opportunity to request the week in which your cabin will be delivered.

An attefallshus is a type of cabin that's been built in Sweden since 2014. It's simply a building of up to 30 square metres that can be constructed on your plot without a building permit.

"Great quality. Great service. When we received the delivery, the interior doors were missing, but the issue was easily solved.”
