Green Retreat garden office
If you are thinking of building a summerhouse, home office or a hangout retreat go and visit Green Retreats amazing show room in Aylesbury. It's worth a trip. I have built a garden office and its amazing. I did a lot of reserach before visiting Green Retreats and I was not disappointed with my choice. My builiding is spacious and looks amazing both inside and outside. The support we have had from Green Retreat staff from purchasing to building to paying for the office has been exceptional. Rachel and the customer care team are great. My one regret is that we were not advised fully on how to do pipe work for the water works and should have done the laying of pipes whilst we had the digger and mapped out where the pipe work needed to go. Oh well live and learn. However, Green Retreats is a great company and I would highly recommend that if you are thinking of putting a retreat in your garden you use this company.

The product is excellent and the service and installation team were great. Polite, tidy, efficient and did quality work. All my queries were answered in a timely fashion.
Green Retreats' excellent and professional teams
I would like to personally thank the base installation, building and electrical teams for the excellent work they have done on my garden house. Their work was of the highest quality and the garden house I have now far exceeds any expectations I had when I first ordered it. The teams did their work with little, if any, disruption or damage to my property and left the site clean and tidy. The base installation and building teams led by Ian and Lee in particular had to handle some unpleasantness from a neighbour, which they did in a very professional and respectful manner. My customer care administrator Rachel also did an excellent job helping to shepherd me through the process (despite the tardiness of my replies!) Green Retreats have excellent teams working for them and I would have no hesitation at all in recommending them to friends and colleagues.
Helpful and efficient, with a beautiful garden room result.
Every person we came into in contact with at Green Retreats was courteous and helpful. The build itself was undertaken with no fuss, efficiency, and good spirits, despite the dreadful weather and was completed on schedule.Very pleased with the result. Would totally recommend.
From the initial enquiry,all the way…
From the initial enquiry,all the way through to completion of the project, Green Retreats have proven to be the most professional company .The customer care team, the surveyor and the amazing build teams,have all been exemplary.The build was trouble free despite terrible weather and the result is a beautiful garden art studio. To say that I am incredibly pleased is an understatement ! Thanks Green Retreats ! Highly recommended .
I am so impressed with my garden room
I am so impressed with my garden room, it doubles up as a music room for my son and an art room for me. Green Retreats were very professional and efficient from start to finish and did a fantastic job. I would definitely recommend them if you want a quality job. Shirley

Stunning garden office
Purchased our garden office from GreenRetreat and could not be happier with the whole process from start (visiting a lovely showroom) through the planning and design and finally to the build. Everything they did was professional and efficient and everything was explained clearly so there was no surprises. The finished product is amazing! Thank you all at GreenRetreat
