Impressed by the team and pleased with our new Garden Room
We are very pleased with the garden room and were impressed by the base, build and electrical teams that were with us last week. All were very professional and good examples of team work at its' best! We would be happy to recommend Green Retreats to any future customers based on our experiences and the quality of the finished building.
Really impressed. Visited the showroom and fell in love with these buildings. After popping down the deposit was built in less than a week and now I'm all up and running with my little office. Everyone that comes to visit is more than impressed and at least one of my clients will be having one in his garden.

Just had a garden room installed and all I can say is the whole process went very smoothly,from the visit to the showroom ,customer care the whole team of installers including the foundation team and electricians to the man fitting the blinds everyone was spot on. The buildings might seem expensive but it’s a quality product,I would highly recommend Green Retreats
Truly exceptional service and quality
After much deliberation and researching for a garden room/office space I finally decided on Green Retreats. The reason, they offer a complete and thorough service with no frills gimmicks or intense sales pitches. The staff are extremely helpful and have excellent knowledge to help support you every step of the way. Each building can be tailored to your needs which is what I like along with the fact all the work is completed by the company from the base to final finishing touches. The overall experience is second to none, with the delivery and installation working like clockwork, to the point where a step was made and delivered to site on the day of installation after realising I wanted a step built. All the workmen were professional courteous and worked extremely hard to ensure the building was installed in two days. Everyone who has seen the building is impressed and I am now looking forward to using my office garden room, I would highly recommend Green Retreats.
