How Much Will It Cost To Add A Glass Extension To My Property?

Home extension with glass elements

If you’re looking for a way to truly impress visitors to your home, a glass extension is the way to go. These extensions aren’t just an excellent investment, they will instantly make your living areas larger while creating an impressive feature to enhance your property. 

Giving you panoramic views over your outdoor spaces, a glass extension is the perfect place to relax at any time of year, giving you a fully immersive experience that brings the outdoors indoors whatever the weather. 

What Are The Benefits Of Glass Extensions?

Glass extensions aren’t just striking and stunning, they bring a sophisticated element to any home. They can also increase the value of your property by as much as 7%, making them a great investment opportunity. 

One further advantage is that they flood the property with light, giving you the chance to entirely open up your home to the great outdoors. Another benefit is that they can reduce your energy bills since the natural sunlight warms the space without the need to turn on your heating. You can also enjoy better ventilation when the weather is warm. 

An Overview Of Costs For Glass Extensions 

On average, you can expect to pay around £3000 per square metre for your glass extension. A glass room extension could cost as little as £14535 but as much as £72000 depending on what you’re looking for from your project. 

Since a glass extension is difficult and time-consuming to construct, the price reflects the extra effort and skill involved. Nevertheless, there are a few ways to make the most of your budget. 

Which Factors Will Affect The Cost Of My Glass Extension?

There are several factors that come into play when it comes to determining the final cost of your glass extension. They include: 

  • The materials you choose – the materials you choose from the frame as well as the kind of glass you opt for will both impact on how much your project will cost. 
  • Extension size – a bigger extension will require more materials as well as more labour hours. 
  • Opening type – the kind of doors you choose, such as sliding glass or bi-fold have their own costs. 
  • Added heating or ventilation. 
  • Extra features – options like lighting, blinds, and power outlets all add to the overall cost. 
  • Flooring – whether you choose laminate, tiles, or carpet, you will need to include this in your price. 
  • The space’s current condition – your budget needs to take into account what is currently in the space where the new glass extension will be build, and the ground’s current condition. It’s possible that you will need to pay more for damp proofing membranes as well as underpinning so your extension will be secure and stable. 
  • Cranes – large panes of glass are unwieldy and heavy, so you may need to hire a crane to install them which, of course, adds to the cost. 

Types Of Glass Extension

There are several kinds of glass extension you can add to your property to suit your budget. A conservatory is one of the cheapest glass additions to your home, but it won’t be entirely made from glass. A true glass room will cost on average £43267, but there are smaller options that will reduce the costs. 

A glass side return extension is a cheaper option, slotting perfectly into an unused space alongside your property. Practical yet attractive, you can expect to pay around £2000 per square metre for this type of extension. 

Is A Traditional Extension A More Affordable Option?

A traditional extension has long been a popular choice amongst homeowners who cannot afford or don’t want to relocate but require more living space. A standard extension isn’t made out of glass and will look like the rest of the property once complete. 

A glass extension will cost more per square metre, but since it will usually be smaller than a regular extension, it should cost less overall. A typical traditional extension will cost you about £68750. 

Could I Install My Own Glass Extension?

If you are a beginner, you shouldn’t consider installing any type of home extension. It is a complex and large-scale project that requires specialist skills and knowledge. For a start, you need to ensure your measurements are exact since large glass panes are costly and if you buy the incorrect size, you could spend a lot of money needlessly. 

Also, since glass panes are large and heavy, you cannot install them yourself. You may need to hire a crane and several workers will be needed to install them safely. Furthermore, you need to comply with building regulations, and only a tradesperson will know those regulations and be able to comply with them correctly. 

If you fail to complete your glass extension to a suitable standard, you could be risking leaks that could give rise to mould and damp. Even worse, you or a family member could be injured and your property could be damaged. 

Therefore, using the services of a professional is vital. Of course, you should always take the time to get several quotes and to check reviews to make sure that you are choosing a reliable and trustworthy company to carry out your glass extension project so that you can have complete peace of mind. 

Do I Need To Get Planning Permission For A Glass Extension?

Just like adding a traditional extension, planning permission has to be obtained before you start work on building a glass extension to your property. Make sure that you check with your local planning authority before beginning any construction work on your home. 

A glass extension is an excellent way to introduce more ventilation and light to your home, and it can also boost its value by as much as 7%. While it may seem expensive to add a glass extension to your property, you could pay as little as £14535 depending on the size, extras, and materials you choose. If a glass extension isn’t right for you, you could consider a more affordable conservatory instead.
