I took a long time researching many different options for my much wanted garden building to use as an art studio and the quality of Green Retreats’ buildings could not be matched. Whilst the team in the showroom are great and all very helpful I cannot praise Steve and his team who came out to install it highly enough. They were all very professional and efficient (and smiling despite the awful weather each day) and Steve as team leader made sure everything went exactly to plan. The electrician who came to connect everything to the house was great too and explained how I could have the outdoor sensor, head/deck lights, wall lights and panel lights set to switch separately and therefore more practically for me which was so appreciated. Not only a great product but such a great team from the shop floor out to the installation. Thank you so much.
Excellent product and service
Excellent product and service, everyone who was involved in my home office's construction were pleasant and helpful to deal with. I love the finished result, it really is the best way to add space to your home without hassle or major expense. Mine is to be used as a photographic studio, but to be honest I love it so much, I think I'd just have one anyway as it adds extra space to my home perfectly and i just like sitting in it and looking at the garden!
Absolutely over the moon with my Green…
Absolutely over the moon with my Green Retreats Expression garden room. Perfection! Great team of lads from groundwork /erection team and electricians not forgetting Rachel who oversaw the project. Cannot fault the service in any way. They will be my first stop if I need any other garden building.
We simply love our Expression Garden…
We simply love our Expression Garden Studio, I cannot rate this company highly enough. The whole experience from the easy to use on-line configurator, visiting the showroom which is packed with inspiration and ideas, the sales support team, the ground workers, Tom and his team of installers this week, working in very difficult weather conditions right through to the electricians and finally the blinds being fitted. The whole experience has been first class from start to finish.
New garden room.
Very impressed with all aspects of Green Retreats From start to finish the whole process was very professional, from the initial design, through to the installation team and the support staff. We are enjoying our new room and would thoroughly recommend Green Retreats.
Professional and pleasant
Professional and pleasant, a company delivering on their promises. No haggling or up-selling, a totally transparent process. Installation teams friendly and hardworking. Delighted with the quality of our garden room. Highly recommend this company.

Great company to deal with!
So pleased that we were recommended to Green Retreats. From the moment we visited their vast showrooms at Westcott to sitting here today in our wonderful new garden room, the experience could not have been better! This is a very professional company that obviously takes pride in its people and the quality of its installations. We were kept fully informed from start to finish, the chaps that installed our garden room arrived on time even after a three hour journey. They were extremely hard working and paid great attention to detail. I can’t praise them highly enough and would be more than happy to recommend them.
