Flat Pack Garden Rooms & Buildings

The possibilities are endless if you want to construct a self build SIPs garden room with our flat pack kits. Many of our clients design a room to build using our SIPS panels and, with our input, they create some very special buildings.

Our flat pack garden rooms make a self build garden room pretty straightforward. We sell a range of sizes and specifications. These range from a basic shell in many sizes where you can choose your own cladding to finish the room. Other options include a full kit with everything you need for a complete garden building.

Flat Pack Garden Room Configurations

We have three types of flat pack garden room kits available. This means you have a choice of how little or much they want their kit to contain.

Shell Garden Room Kits

Each flat pack garden room kit includes the SIPs required to construct walls, roof and floor as a shell. You then complete it with the external cladding, glazing and internal finish of your choice.
