Reviews

Really, really pleased with it

Really pleased with it all and enjoy sitting and taking in the view, glass of wine in hand of course! We did new decking immediately outside of it, in order to open the bi fold doors fully as an extension to the room. All in all, really, really pleased with it.

Such excellent service!

My wife and I just wanted to thank Richard, yourself and the rest of the team for all the support, ad hoc technical tips and advice that we got whilst building our Garden Room. I know that I visited the show room 2 or 3 times and Richard and the team, even though quite busy, showed us every courtesy and help. Such excellent service! I have finally completed the build of our 3 x 5m Garden Room, and we are very pleased with it.

The kit was fantastic!

Here are some pictures of my project I completed about 2 months ago, the kit was fantastic!

It’s such a good design!

We love the room and it was so easy to build. It’s such a good design!

It’s perfect and we love it!

We use it as a gym and use it most days, it’s perfect and we love it!

Great customer service and I’ll definitely be using you guys again.

Just wanted to email to thank you and your team. Great customer service and I’ll definitely be using you guys again. The driver was a really nice guy and very helpful. The build went really well and the customer was very happy.
