What is the difference between glass extensions and conservatories?

A glass extension is a great way to enjoy your garden, no matter the weather! They can be considered an enclosed part of your garden, unlike a conservatory which is often used as a second living room.

Glass extensions can be seen as a more permanent version of a conservatory, but how do they differ from a conservatory? Glass extensions are not as common as glass conservatories and aren’t always included in building regulations. Glass Extensions are typically built onto the back or sides of your house. They usually have some kind of roofing on them, that allows light into the room below. Glass Extensions usually cost less than glass conservatories because they don’t require planning permission and they’re generally smaller than glass conservatories. Glass extensions are fantastic additions to any home!

Glass Extensions

  • They extend your living space – Glass extensions are perfect for extending your living space. If you have a garden that’s just sitting there, then why not enjoy it all year round? Glass extensions can also be used as another entertaining space or maybe even an extra room for the kids!
  • They’re low maintenance – Glass extensions don’t require much in regards to maintenance compared to other types of building work. This is because they’re made using toughened glass and usually supported with steel frames, so you won’t need to worry about leaks or rot!
  • Cheaper than conservatories – Glass Extensions aren’t as expensive as glass conservatories and don’t require planning permission before installation, meaning they’re cheaper and easier to install.
  • More modern design – Glass extensions are a more modern take on conservatories. Glass extensions have sloped roofs and different designs, whereas glass conservatories have a curved roof or terracotta style roofing.
  • Easier to install – Glass extensions are easier to install than glass conservatories too! Glass extension installation requires the same amount of planning permission as a single storey building would need, so it’s quick and easy to get one installed!


  • Restricted views – Framed windows and wall components in conservatories can restrict views. Glass extensions don’t have this issue as they’re made from toughened glass! Glass extension roofing panels are also sloped, so you can enjoy a great view from them.
  • Design limitations – Conservatories are usually restricted to predetermined shapes and sizes. Glass extensions on the other hand, can be built to any shape or size you want! Glass extensions are more customisable and offer a better solution if you’re struggling with space at home. Glass extensions can even be installed onto slopes – perfect if your garden is on a hillside!
  • Appearance of conservatories – Glass conservatories have traditional looking designs which feature curved roofs, whereas glass extensions have sloped roofing panels that resemble modern house styles. Glass extensions don’t fall into any design category as they can be designed however you want them to look.
  • Harder to insulate- Glass Conservatories require a different type of insulation that’s not included in building regulations, meaning it is harder to fit compared with Glass Extensions.

What to consider before buying a glass extension

Planning regulations –

Glass extensions are not included in building regulations, so you must check with your local planning office before installing one. Glass conservatories are included in the building regulations. Glass extensions don’t require as much consideration as glass conservatories do because they’re smaller and have sloped roofs.

Privacy –

Glass extensions are not as private as Glass Conservatories. Glass conservatories have more glazing surfaces that allow light into the room below, but still provide you with privacy. Glass extensions only have one wall of glass which isn’t suitable if you’re looking for added privacy.

Maintenance –

Glass extensions are low maintenance compared to Glass conservatories. Glass extensions only require a quick clean every now and then, whereas Glass Conservatories need more regular cleaning due to their glazing surfaces. Of course, just like for the windows in your house, you’re likely to want to get a professional around to clean you glass extensions every now and then!

Glass conservatories need more care as they’re often made from wood and double glazed. Glass extensions are made from toughened glass panels that don’t require much in the way of regular maintenance.
