Very impressive project management from start to finish. Helpful, organised and efficient. I'm very pleased with the whole process.
Our Green Retreats garden office with storage area.
Our Green Retreats garden office with storage area (at the back, partitioned from the office and with it's own door), was completed two months ago, and my wife and I are delighted with it. The building is well-designed and well-built, with excellent insulation and a plaster and paint interior finish, with our choice of paint. The air con heating and cooling works well and makes little noise. The project went smoothly from start to finish. GR staff were attentive and professional. They listened to what we wanted, checked they had understood gave good advice, and did what they said they would when they said they would do it at every stage. The specification and pricing was detailed, and all the work was done to a high standard. (We were responsible for site clearance and levelling, although GR surveyed the site at the start and checked progress. We chose an excellent local electrician to arrange the power supply from the house, although I am confident GR would have done that to a high standard, also.) The process could hardly have gone better, and the end result is brilliant.
Thank you x
Thank you for such a smooth and professional experience . Both the base team and the installation teams were great. We couldn't believe how quickly it all came together and the the quality and finish is excellent. Communication from Celia was also amazing!
Great finished product, great customer service
I had a smaller garden unit built as an office / homebrewery in SW London and could not be happier with the excellent finished product and good customer service. Highlights have been, good finished product, responsive to questions, efficient and friendly contractors, able to accommodate any requests. I usually prefer to leave a comment on what could be better, but in this case I struggle to come up with anything relevant.

Following on from the garden room being installed last week,for the last couple of days Josh has been plastering the walls. Again, the service has been excellent and extremely professional. A great job done to time. Thanks very much indeed.
Martin Dunford's team (Green Retreats)…
Martin Dunford's team (Green Retreats) has spent the last few days building the garden room in my garden. It has been terrible week of rain, sleet and wind but everyone has been polite, helpful and cheerful despite these awful weather conditions. I couldn't recommend them more highly.
