We are delighted with our garden gym…
We are delighted with our garden gym from Green Retreats. Everything has gone smoothly from the design consultation, to the site visit, to the build. Visiting the showroom is really useful as you can see a range of different styles and set ups and the consultant set out our options really clearly. We then got an online design which we could tailor to our exact needs. When it came to the build we got a really clear schedule and the build went exactly to plan - we were so impressed with the work and professionalism of all the team doing the build. We are getting lots of compliments from family and friends about how good it looks ! Can't recommend them highly enough !
Thrilled with my garden room
This company is very professionally managed and delivered an amazingly beautiful result. I’m thrilled with my garden room.
Green Retreats quality Garden Room
Green Retreats have built an amazing Garden Room, which will allow me to have my own office space. The building is well made, looks good, is light and airy, but warm - the radiators heat the room quickly and the heat is retained due to the high quality of the building structure. All in all, the best decision I made in 2020!
Team were great & we’re really pleased…
Team were great & we’re really pleased with the building!
We’ve never had the pleasure of dealing…
We’ve never had the pleasure of dealing with a company and a product as outstanding as Green Retreats and their Garden Rooms. From the moment the exquisite brochure landed on our doormat right through to the “final fix, the quality, care and attention to detail that Green Retreats displayed at every step were all first class. Our Garden Office is absolutely superb ( We cannot find anything online to touch it…which is why we were prepared to travel 3 hours from our home to visit the Green Retreats showroom before placing our final order! ). The quality of our Garden room is equally matched by the professionalism and care we received from all the staff at Green Retreats, right through from our wonderful Customer care assistant, Mikayla, to the friendly, helpful and courteous team, led by Andy, who skillfully assembled the Garden office for us. We cannot recommend Green Retreats highly enough, the product is fairly priced, the build quality and workmanship are superb and the customer care second to none. A Massive, “Thank You” from us to everyone at Green Retreats; we will enjoy our Garden Office for many years to come. It has enhanced our garden immeasurably and has already become a key feature and focal point! As an aside, the project was made to be really fun and easy ( thanks to the brochure, online 3D configurator and wonderful staff ) and has been a great adventure for us! Dave and Helen Lockett.
Green Retreats were absolutely fantastic
Green Retreats were absolutely fantastic. This is quite simply the most straight-forward building project we've ever done. GR's online portal made the whole process so easy to manage, there was always a human being at the end of a phone if we had any questions and every member of staff that we met was polite and very helpful. The garden room itself is a fantastic addition to our home and we're absolutely thrilled with it. Nick and his team were incredible, even working steadily in snowy conditions. An all-round great experience with this company - can't recommend highly enough!
