Why have an insulated garden room?

A well insulated garden room will provide a space that is warmer in the winter and cooler in the summer. It can also save you money on heating and cooling bills as you will be able to go longer into the year before needing to turn on your heater or engage your air-conditioning.

The best that money can buy

Our insulated garden buildings are constructed using 100mm Rockwool slabs for the walls and ceiling and 90mm, high-density foil backed insulation for the floor. We also use double-glazed, argon-filled windows and doors for the best possible U-Value.

Our Delighted Customers

Lord Alan Sugar – Entrepreneur
“After looking at numerous garden rooms and luxury wooden gazebos on the market we decided to go with Crown Pavilions as their buildings are undoubtedly the best that money can buy and the service level was exceptional. They exceeded our expectations at every stage. If you are looking for the best garden buildings on the market, then Crown Pavilions is the company to hire!”

“When I first saw this pavilion I thought it was just ace. It was the best we had seen, it was exciting. In fact just sitting in the pavilion now, I’m excited. Even though this is a building outside in your garden it’s still very luxurious, but yet multi-functional. Particularly for us, alfresco dining is such an important part of our life and to have this lovely round table and its curves matching the curves on the pavilion is just perfect.”

“I love the Crown Pavilion; we have just had our second installation in Darlington. The first one was at our Hastings hotel four years ago and it has weathered beautifully. They both look fantastic. The team were amicable, efficient, they turned up on time, got the job done, just a great company to deal with.I would certainly recommend Crown Pavilions.”
