Right from the very beginning, Green Retreats were fantastic to work with and supported us throughout. Every detail was discussed, no matter how big or small the detail. We couldn’t believe how quickly the project was completed. A grand job by all concerned at Green Retreats, thank you for the new building!
Fantastic experience from start to finish.
Fantastic experience from start to finish. Everything was so simple and straightforward. And what made the difference was dealing with real people, from the site survey and build in person to someone (Amanda) being at the end of the phone for any answer or issue. Amazing service, always friendly. Always on time and never too much hassle. The quickest process ever. Would not hesitate to use again.

Amazing service from start to finish!
Amazing service from start to finish! The communication and planning is first-class, which helped the build go super-smoothly. We are extremely pleased with the finished result!
Outstanding service & superb buildings
Green retreats have probably been the best company I have had dealings with as far as I can remember. The customer service in every area has been outstanding. From Initial dialogue and communication with the GR Staff and every team that were sent to do their part (Consultation, Fitters, Electricians, Flooring , Air conditioning etc ), the experience has been faultless. The building is superb (Sound proof pack) and the soundproofing is well beyond what I expected. I would seriously advise anyone looking for an outbuilding / office to put Green Retreats at the top of your list. The LG air conditioning is also a God send - to be able to get the room warm via an app on my phone before entering the room in the morning is a seriously good perk! Chuffed
Very impressive project management from…
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.
