What factors will impact the cost of your glass extension?
Because our glass extensions are fully bespoke, there are several factors that will impact the final cost.
Size and complexity
As you’d expect, the bigger your glass extension is, the more it will cost. Similarly, if you choose a complex design, this will cost more than a very basic glass extension.
When you contact us for a quote, we’ll ask you for an estimate of the dimensions for your glass extension. Don’t worry about being completely precise – we’ll come to your property and take accurate measurements if you choose to go ahead with your project.
Type of glass extension
Our glass extensions are available in 5 different styles, each boasting its own unique set of features and characteristics that you can customise to suit your needs.
- Vue Pod glass room: A classic glass extension with a sleek, minimalist design and stylish aluminium beams along the flat roof.
- Ambient glass room: This glass extension is similar to the Vue Pod style, but features an eye-catching pitched roof instead of a flat roof.
- Vue Grande glass room: This glass extension has a luxurious cubist design with a sophisticated front overhang built into it.
- Ascend glass room: A stylish glass extension with an elegant pitched roof designed to effortlessly enhance your property.
- Vue Primo glass room: This style features a flat roof with statement rafters, making for a bold look.
Additional features
There are a variety of additional features you might choose to add to your glass extension, which will also impact the final cost of the structure.
We build all our glass extensions and other garden rooms modularly, so you can choose to add extra features at a later date if you’re not sure whether you want them at the time of installation.
Some of the features you can add to your glass extension include:
- LED lighting: LED lights can be built into the roof of your glass extension to beautifully illuminate the space at night.
- Infrared heating: Comfortably enjoy your glass extension even on chilly winter days with built-in infrared heating.
- Drop-down screens: Make your glass extension more private with remote-controlled drop-down screens.

Glass extension cost FAQs
Is a glass extension cheaper than a traditional extension?
One of the best things about glass extensions is that they are often cheaper than a traditional brick extension. This is because glass extensions typically require less structural work and don’t need planning permission in most cases.
Despite being cheaper, glass extensions are just as durable and weather resistant as brick extensions. They’re made from toughened glass and high-quality aluminium, materials that are designed to stand the test of time.
Do I need planning permission for a glass extension?
No, glass extensions do not require planning permission in the majority of cases. If your property is one of the few that does require planning permission, we’ll be able to assist you with the process to make it easy and stress-free.
Check out our guide to planning permission and building control for more information.
Do glass extensions require any maintenance?
Generally, glass extensions require very little maintenance. The roofs are pitched at an angle that allows dirt and water to roll right off, so you won’t have to clean yours very often.
If the roof does need cleaning, simply use a power washer or hose to remove any dirt, scrubbing at any stubborn spots with a damp cloth.
What is the average lifespan of a glass extension?
A glass extension is designed to last for at least 30 years, but with the proper care and maintenance it can last a lifetime.
