Fantastic Room in a little London garden!
We now have an amazing room at the bottom of our garden that fits in beautifully and feels as though it has been there for ever. All the staff were incredibly helpful and friendly and the entire process was very straightforward.

Excellent choice of supplier for my Garden Studio! So pleased
Green Retreats deserve every single one of my star ratings! They have been very professional right from the start, from welcoming me to their warehouse to helping me make the right choice through to a fabulous installation. The finished studio is amazing, a top quality build and the installation teams were timely, polite and very hard-working.
Thanks to you all…what a fab company!!
by Alexa Garthwaite
Fantastic product and service to match
We had a 3.5m by 5m garden room installed last month and we are delighted with the result. We are using it as a home gym and love the extra space it has given us! The building also looks fantastic at the bottom of our garden. Green retreats have been an absolute pleasure to deal with. In summary I have been very impressed by both the product and the service provided by green retreats and highly recommend!
Insulated Garden Room FAQs
The great news is that planning permission is generally not required for insulated garden rooms! Garden rooms like ours are classed as ‘outbuildings’, which fall within your permitted development rights. Some properties and areas in the UK don’t have permitted development rights, in which case planning permission would be required. We can help with the planning application process on your behalf should you need it, taking care of the hassle for you.
Yes! All of our garden rooms are fully insulated to use all year round. Our premium-grade insulation helps regulate the temperature of your garden room to keep you warm in the winter and cool in the summer.
Absolutely! Luke Jackson, a Michael Graham Estate Agents property expert, noted: “We’ve seen firsthand the significant impact the pandemic has had on homebuyers. With remote working now so common, buyers’ priorities have shifted. An insulated garden room, separate from the main house, can now be the deciding factor in closing a property deal.”
A garden room’s cost will depend on the size, model and additional upgrades you opt for. For a fully insulated building, garden rooms start from as little as £9,860.
Our insulated garden rooms are designed to keep your valuable work equipment safe when you’re finished for the day!
The insurance-grade doors and windows keep your garden office secure. The premium double glazing is designed to withstand considerable shock compared to traditional options.
