Amazing customer service
Amazing customer service, great showroom and knowledgeable staff that took us through the design and ordering process. Big shout out to Ella who looked after us.
Exceptional experience, fantastic installation.
Green Retreats have been fabulous. The Basebox is great, but what impressed me most were the teams who showed up at our house to install our garden room. I can't remember ever watching people work so hard and so diligently. The foundations team finished early, the installation team took one day to complete a two-day installation, and the electricians and air conditioning teams worked non-stop in some of the most atrocious weather conditions I have ever seen, finishing a two-day job in one day. The quality was excellent throughout. No corners were cut and everything was finished beautifully, including the clean-up afterwards. I highly recommend Green Retreats. Initially I thought that our garden room was relatively expensive, but after such excellent service and installation I realise that we got excellent value for money.
