Self-build Garden Room Kits

In our constant quest to ensure that everyone can afford a Garden Room, we are proud to introduce our new range of Self-build Garden Room Kits.

Starting at only £9,860.00, these come with everything you need to build your own Garden Room, including tools, paint and full detailed instructions. If you can assemble flat pack furniture, you can build one of these kits yourself. If you’re not confident to do it yourself, any local carpenter or builder (or even a friend who’s good at DIY) will be able to assemble it for you quickly and easily.

So now you can build your own Garden Office, Studio, Gym, Treatment Room or Bar in your own garden. Read on for full details.

“I would 100% recommend this self-build garden room kit”

“I’m so glad we decided to get our Square Self-build Garden Room Kit! We have a tiny garden and I was amazed at how it turned out and how easy it was to put together.

If you’re someone who has a narrow garden I would 100% recommend this self-build garden room kit.”

How it’s Made

Walls

Using high-standard raw materials the panels are constructed from a 9mm thick white MDF board, 75mm thick polystyrene insulation, and an engineered wood-composite panel exterior that is treated for protection against rot and decay and is ready to be painted to your chosen colour.

Flooring

The sub-floors of our Self-build Garden Room Kits are engineered to sit slightly off the ground to allow air to circulate and remove any risk of rising damp.
Constructed from 80mm polyurethane insulation that is backed by 1mm of powder-coated steel on top and bottom.

Roofing

The roof is composed of an 80mm thick insulated steel SIPS panel and backed by 1mm of powder-coated steel on top and bottom. 0.5mm thick galvanised steel roof sheet panel sits on top.
The roof is pitched with a slight slope from front to back, allowing water to run off efficiently to the rear.

Glazing

The doors and windows throughout our Self-build Garden Room Kits are hard coated, low-e Pilkington K Optiwhite ‘extra clear’ double-glazing, which is argon filled and fitted with a Planitherm layer and Swisspacer.

This provides superior insulation and energy efficiency.
