What our customers say

We are so pleased to be top rated on Trustpilot
by our customers.


A garden room is a freestanding building separate from the home to create a luxury space designed to work, relax or play in. By opting for a quality built and insulated garden room, you can create space that can be used all year round. Discover more about garden rooms.

In most cases, garden room buildings in the UK do not require planning permission as they fall within permitted development rights. There are a few exceptions, including your location and where you want to place your garden room. Read more about garden rooms and planning permission here.

A garden room provides space for endless uses, including a garden office, home gym, garden art studio or even garden bar entertainment space. The benefit of choosing an insulated garden room is it can be used all year round, just like any other space in your home. View all our garden room popular uses.

A garden room cannot be used full-time as self-contained living accommodation as this falls outside the permitted development rules. However, you can use a garden room as an occasional guest bedroom.

Great news, a high-quality garden will add value to your home or property as it is extra space that is useable all year round. In a recent study by Rightmove, garden room home offices were revealed as the number one desired feature by homebuyers today. Find out more about how much value a garden room will add.

A garden room typically takes between 2-5 days to install by Green Retreats. This can be longer when upgrades such as plaster are chosen. Read our complete garden room installation timeline guide here. Garden Room Installation.

Do garden rooms need planning permission?

The great news is that garden rooms are designed to fall within your permitted development rights, and as such they very rarely need planning permission.

If for any reason your project does require planning permission, you can relax knowing that Green Retreats will take care of the application process on your behalf. Find out more in our planning permission page, or by visiting the garden rooms and outbuildings page on Planning portal.
