What people say…
-
Absolutely love our Pent Haus garden room! We recently had one installed, and I can’t tell you how much I love it. Both of us work from here during the day, and even after work, I stay out here to relax—we’ve got a TV and sofa set up, it’s made such a huge difference to us. With a young family, it serves as a workspace, play-space, chill-out space, and occasionally a sleepover spot. It really ticks all the boxes! The quality is outstanding. I only have a small electric heater, and the room keeps really warm — it’s incredibly well insulated.

July 15, 2025As an independent contractor for a number of garden building companies I have the pleasure of working with a wide range of products. I can honestly say that Pent Haus are up there with the top in terms of their quality and customer service. Every single aspect has been well considered from design through to the installation process which makes them a fantastic company to purchase a garden building from.

I have recently had a Pent Haus garden room built and I’m delighted with it. Everything about this company works so well! From being able to configure your building through the website, to refining it and being able to ask for advice before you make your final decision to the delivery and aftercare. Our installation team commented on what excellent quality the materials are and said it was a pleasure to build. I’m so pleased we used Pent Haus, thank you Tom and team!
