More information

  • Delivered as modular construction for easy installation
  • Configured for use as an additional residential building
  • Receive help from our Polhus contractors for ease of assembly 

Mariedal 30 sqm is one of our new prefabricated Garden house models from Polhus. The structure is designed to the latest Swedish standards for ceiling height, energy conservation and disabled access. The Garden house has plenty of space for a kitchen, hall and bathroom. Above the bathroom is a cosy sleeping loft.

The wide, slatted glass doors add an airy feel to house, filled with natural light.

Whether you are looking for a permanent holiday home or a charming additional space for hobbies, Mariedal is the house for you. The house offers plenty of scope for a variety of uses, including rental opportunities, extra living space, offices or a guest house for relatives and friends.

After selecting the housing plot, the foundation should be laid based on our instructions. Dig out the topsoil on a ground area larger than the building, install plinths and level the surface with gravel or macadam. 

Since the garden house is prefabricated we can offer speedy delivery. The walls are sent as modular parts that you can easily and quickly assemble on site. Both the floor joist and the roof construction are pre-cut to the correct lengths and dimensions and assembled using our manual. If you have questions during the assembly process, you are always welcome to call our customer service and talk to one of our building experts.

If you do not want to assemble the house yourself, we offer installer packages as an option. Then our experienced Polhus contractors will visit and assemble the house for you, hassle free.

The Garden house Mariedal is delivered as a kit. Alongside the main body, you can find additional options such as insulation and roofing which you can add to your order. Mariedal is a light and lovely garden house that you will enjoy for many years to come.
