Glass Garden Rooms UK — The Complete Guide
What Is a Glass Garden Room?
A glass garden room is a modern outdoor structure that combines panoramic sliding glass walls with a motorised louvred roof — creating a fully enclosed space you can use 365 days a year, while retaining the open-air feeling of being in your garden when the weather is good.
Unlike a conservatory, which is permanently enclosed and often overheats in summer, a glass garden room like the PergoEnvision gives you total control. Open the louvres and slide back the glass for a fully open pergola experience on warm days. Close everything for complete weather protection in winter.
PergoEnvision — Glass Doors Included as Standard
Every PergoEnvision comes with sliding glass doors included as standard — this is not an optional extra. The price you see is the price for a fully enclosed glass garden room:
- Wall-mounted configurations — sliding glass doors on all 3 open sides, included in the price
- Free-standing configurations — sliding glass doors on all 4 sides, included in the price
