A1- initial build.
This review relates to the initial install team (apparently they are team 23). We installed our own base for the project. The guys for the team turned up at 7.30am on the dot on Monday as expected. They introduced themselves and got straight to work completing the construction in just under 5 days as planned. Not bad for a 30sqm building. They were an absolute pleasure to have on site. Always friendly, and they took the time to keep me updated at the end of each day, and they've pointed out the snags that they will need to be resolved before final sign off. One of the team even helped me adjust the existing bi-fold doors in my house which were sticking. A1 for this install team, thank you. Next week it's the plasterers turn, so hopefully they'll be as good.

I would thoroughly recommend Green Retreats. Whole experience through viewing options , placing order, installation and finishing the project has been seamless and easy to navigate. We are very pleased with our garden room and look forward to many years enjoying our garden cabin. Mark Oxford
Fabulous professional service from…
Fabulous professional service from beginning to end. All the tradesmen were totally trustworthy, friendly, clean and efficient. Couldn't have asked for a better experience - the only trouble now is that we'd like to design and install another but can't. Green Retreats come fully recommended by us.

110% Happy with our room
We ordered our garden room online in September 2020. I was lucky enough to have my installation in February 2021. The process from order to completion was excellent. Every member of the team from the survey to the final installation of the air conditioning were friendly and informative. The install team were on site for 3 days and to be honest we missed them when they left. Great guys working for a great company. Highly recommended.
Faultless from start to finish.
The whole process of buying my garden office was faultless from start to finish. The brochure and design features were excellent. Communication throughout was good leading to a completed building with which I am delighted.
We thoroughly recommend Green Retreats and their staff
My partner and I have felt for some time that our house wasn't quite big enough for our current needs. We love the area and our neighbours are brilliant. Rather than moving, we decided to have a garden room/office instead. After checking out various companies online we decided to go with Green Retreats and we couldn't be happier with the results. From the start, we've been very impressed with their staff, right from visiting the showroom to all the different workmen that have been around at different stages to build our garden room. The work was done in stages and started approximately 5-6 months after we placed our order. Week 1 - Base, Week 2 - Garden room assembled, Week 3 - Plastering, Week 4 - Electrics + Final fixes. We thoroughly recommend Green Retreats and their staff.
