Excellent quality and service - highly recommend
Extremely impressed with Green Retreats from start to finish We ordered a 7 x 4m Pinnacle cabin From the initial survey, flexibility with the online configuration, customer service responsiveness and excellent quality of workmanship - it’s been a seamless and very efficient and consistently high quality experience from start to end I had a number of queries and requests, which were all dealt with very efficiently. My wife and I are very happy with the end result We’ve worked with other building / renovation companies in the past - but this was by far the best experience Each of the specialist workers (foundation, plasterer, painter, electrician, aircon) were very consultative and capable, as was the customer service rep (Rachel) In particular I’d like to call out Matt and his team who did the bulk of the work building the cabin, working tirelessly until late in the evening to get the job done on time. Really excellent Thank you
Outstanding end to end service
We looked at several online suppliers of garden rooms but settled on Green Retreats for a couple of reasons; firstly, for their attractive, modern design and secondly, we liked the all-inclusive pricing. The end to end process of configuring the building, placing the order, ground works, installation and post sales service was outstanding. The build quality and the materials are all of the highest order. Communication was excellent at all stages. Even when there were a couple of small snagging issues post build, the Green Retreats team drove out to our property and resolved these quickly and professionally. The project is now nearly complete and the building looks stunning and its surroundings. It has definitely exceeded our expectations and we would highly recommend Green Retreats to anyone looking to buy a garden room.
Beautiful garden room & stress free…
Beautiful garden room & stress free process! I can't rate Green Retreats highly enough, the whole process from first visiting the showroom to completion was all so easy and straightforward. We needed planning permission, due to being a listed building, but Green Retreats helped us with the drawings and materials to make this part as easy as possible and we kept in touch throughout the process to make sure we could start the build as soon as permission was granted. After this it was just 4 weeks from start to finish. All the builders, plasterers, painters, electricians etc. were very polite and helpful with any queries we had. I would recommend green retreats to anybody.
A great job from Green Retreats
From start to finish the process was very smooth and everyone we dealt with at Green Retreats were helpful, informative and keen to ensure everything went to plan. The garden room is amazing! The finish is high quality and I am sure that we will enjoy it for many years to come.
I am incredibly pleased with the end product and have been incredibly happy with the service received from every person I have dealt with from Green Retreats! Every part of the installation was carried out by a friendly, informative and helpful team! We absolutely love our retreat which has created a great working space away from the house! Thank you very much 😊
Choosing Green Retreats was one of the best buying decisions I have made
Choosing Green Retreats was one of the best buying decisions I have made. From start to finish, they were professional, helpful, thorough and efficient. The garden office itself is exactly as was chosen. Every detail was precise and well explained, in person at the fabulous showroom, and in the subsequent documentation. Without exception, everyone we dealt with was organised, pleasant and attentive. I couldn’t speak more highly of the service received nor the product. Thank you very much.
Excellent experience from start to…
Excellent experience from start to finish, really happy with the garden room. The guys who came to do the work were polite, friendly and very helpful in dealing with our needs. I would not hesitate to recommend them.
We are delighted with our new Green Retreats garden room which had its final fit last week. The whole process, from visiting the showroom (which was extremely useful), through survey, ordering and various stages of building has been well managed and well executed. Our customer service contact, Celia Hodgson, has been very helpful and supportive throughout. All the build teams have been professional, friendly, hardworking and made a good job of clearing the site at the end of each visit. The only issue which caused slight disappointment and frustration was lack of communication when planned visits were changed on 2 occasions and I was not informed, but had to phone the office to ask where the expected teams were! However, this only caused a day’s delay each time and customer service was very apologetic and sorted it promptly. Overall, our experience with Green Retreats has been excellent and I would definitely recommend them. We have been so excited to start using the lovely new space this weekend. Thank you to all the teams involved.
