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!
Home Gyms FAQs
If you are interested in one of our garden room buildings, contact us for a comprehensive brochure & price list, along with any additional queries you may have. A visit to one of our showrooms gives you a real feel of the quality we offer and is a great way to start your project. We provide a free on-site or virtual design consultation service, allowing us to have a comprehensive look at your location, land and access. During this meeting, you are provided with samples of the building, and together we can design the perfect garden room to suit your requirements. Come and visit us at one of our showrooms to get your garden gym journey started!
Planning permission is not normally required as our buildings fall under permitted development (built under 2.5m high externally). Most houses, even in conservation areas and areas of outstanding natural beauty (AONB), have permitted development rights. Flats and listed buildings have no permitted development rights, so will always need planning permission. Don’t worry though, as planning is a relatively simple process for our garden rooms and we are on-hand to help with this process. You can find out more about planning permission here.
Yes, we can install partition walls in any of our larger sized garden rooms. Please enquire for more details.
Our garden room structures will need to remain free-standing due to the nature of their construction. However, we can build as close as 400mm to any solid obstacle, such as your house.
We are only able to construct buildings that are either square or rectangular within the Green Retreats range.
We don’t offer a completely soundproof solution for your garden room. We do, however, offer an acoustic pack which reduces the transfer of sound to approximately -45db – however, this is not ‘soundproof’. Although we use industry-leading acoustically laminated glass, this is the least effective component of our acoustic pack. Please bear in mind that the more glass you opt for in your garden room, the lesser the effect the acoustic pack will have.
We offer a complete electrical connection from your house to the garden room at an additional cost, which will be confirmed at your design consultation. However, you are more than welcome to use your own preferred electrician for this.
If you are looking to install a bathroom or other facility that would require water to your building, we would be happy to liaise with your plumber of choice to ensure they are comfortable carrying out all plumbing work required to and from the building.
We use the industry’s leading providers for our insulation and double-glazing for excellent thermal retention. The floor and roof panels are filled with market-leading high-density polyurethane insulation and are double backed for optimum performance. Our highly efficient walls are filled with A* fire-rated natural Rockwool insulation and engineered with a layer of PhotonWrap multi-foil, an air-open reflective insulating breather membrane. All windows and doors are fitted with Pilkington K™ Optiwhite double glazing. Our double glazing is 28mm thick as standard and 28.6mm for our acoustic pack.
Home gyms provide numerous benefits, including no waiting for equipment and privacy. Unlike commercial gyms, garden gyms allow you to do your workouts in peace without disruption so you can focus on your fitness goals.
Garden gym prices vary based on size and optional upgrades. A basic 2.4m x 2.4m DIY garden gym starts at £9,860. This compact option is easy to assemble and can be built in just two days. Larger sizes and additional features are available to suit different budgets and space requirements.
