Eco Manufacturing
Handmade in our UK Factory by our
expert makers
Every Green Retreats garden building is manufactured in our dedicated Buckinghamshire production facility where each part of your building is handcrafted by our skilled makers. From assembling the individual panels to creating our windows and doors, our experienced teams work together to ensure each building meets our high quality control before it leaves the factory.
Many of our makers have been part of Green Retreats for many years, with some having even been with us from the very start! Their experience, craftsmanship and attention to detail are at the heart of every garden building we make.
Why do we build our garden rooms off-site in panels?
Rather than building your garden room almost entirely in your garden, we manufacture the majority of it in our factory before installation. This efficient approach means less disruption at home, fewer deliveries and no need for heavy machinery, while allowing our experienced installation teams to assemble most garden rooms in just 2–5 days. It’s a faster, cleaner and more controlled way to build, without compromising on quality.
The advantages of building off-site
Less disruption
Because most of your garden room is built in panels before we arrive, we give you a clear installation timeline from day 1. You’ll know exactly when we will be on site, helping you to plan around the build to keep disruption to your everyday life to a minimum.
Faster installation
With the main panels already built, much of the construction work is complete before we reach your garden, which greatly speeds up installation. We try our very best to get most garden rooms watertight by the end of the first installation day.
No heavy machinery
Our panel construction method means no heavy machinery is needed to install your garden room. The individual sections and materials are all carried by hand from our vans to your site, helping to minimise the impact on the rest of your garden.
Quality Control
Manufacturing the panels indoors allows us to carefully control quality before your garden room even reaches your site. Our experienced team carefully check each component before it leaves our factory, helping us maintain consistently high quality.
“What I really find exciting about these, as
opposed to anything else really in the market,
is that you can understand how these are
made, you can appreciate their quality and
you can understand the story.”

What our customers say about their installation
We are so pleased to be top-rated on Trustpilot
The installation crews were fantastic too — hardworking, friendly and genuinely respectful of our home and garden throughout the build. Nothing was too much trouble, and they left everything clean and tidy at the end of each day.
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.
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.

Garden Room Manufacturing & Installation FAQs
Green Retreats use its own employed teams to build their garden room, with no third parties used. Doing this ensures complete quality control of every stage of the build from the base right through to the electrics.
Green Retreats garden rooms are manufactured in their purpose-built 60,000 sq ft production facility in Westcott, Buckinghamshire. It sits on the same site as our flagship Buckinghamshire showroom, which is just a 2-minute walk away! We’re proud that our factory is 100% solar powered, contributing to our carbon-neutral status.
Yes, Green Retreats’ garden buildings are fully manufactured in the UK. Raw materials enter our production facility in Westcott, Buckinghamshire, where we manufacture the SIPs panels for our garden rooms and annexes.
No, subcontractors are not used to install Green Retreats garden rooms, instead opting for expert in-house teams across all areas of installation. We are proud to have our very own specialist teams to build and finish your garden room. We even make our own windows and doors for your building, and our electrics are carried out by our sister company that is situated on the same site as us.
Green Retreats garden rooms are installed by our specialist, in-house trained teams, with no third-party contractors. Most builds follow the same process of the base/foundations being installed about 2 weeks before the main building installation commences. The main building then takes between 2-15 days to install, depending on the size and style of building. Once the main structure is finished, teams will attend to complete any optional extras including plastering, electrical connection and air conditioning.
On average, it takes 2-15 days to install a Green Retreats garden room, but this can vary to the size and style of building you choose. A B-Range is typically installed in 1-3 days, a G-Range is typically installed in 2-5 days, an A-Range is typically installed in 5-9 days, and an X-Range in 7-15 days.
If you’ve selected plastering or our acoustic pack, the overall process may take a couple of weeks longer to allow for plaster drying time.
Manufacturing the majority of your garden room before coming to site allows Green Retreats to speed up the time it takes them to build your garden room. This ultimately means less disruption to your home and garden, removes the need for heavy and noisy machinery and allows complete quality control.
Yes, it is highly advised to visit a Green Retreats showroom to see all the options, materials and quality in person before ordering. We have two showrooms to choose from: our flagship showroom with 24 buildings on display in Westcott, Buckinghamshire or our smaller hub showroom that has 4 buildings on display in Twickenham, London.
