Garden room

We ordered our garden room in January and waited until July for construction. The whole experience with Green Retreats has been exceptional and they must be one of the best companies I have ever dealt with. Extremely professional company who did everything they could to help us throughout the entire project. The brochures and initial design specification on the website was first class. The visit by a site planner went smoothly and was peace of mind for us. They took one day to lay the base, three days to construct (5 metre by 3.5 metre) and half a day for the electrician. We had a bit of an issue with the professionalism of one of the construction crew but this was hardly the fault of the company. We chose the Pinnacle design and it looks absolutely fantastic and we are very pleased with how it has turned out. Exactly what we wanted. We now have a combined home gym and office away from the home (about 200 feet from the house). The only negative feedback I would give was the electrician quote to run armoured cable from the garden room to connect into my garage was extortionate. I think I was quoted in the region of £1600 and decided to get my local electrician to do this part of the work for £450. Would highly recommend Green Retreats to construct a garden room for their utmost professionalism from start to finish. I would also recommend a visit to the showroom in Aylesbury which gave us some new ideas and a tweak of the plan to incorporate some extras. Thank you Green Retreats.
