Do I need planning permission for a glass extension?

It is possible that you will not have to acquire planning permission, but only if you have Permitted Development Rights. Glass extensions in Kent must comply with a lengthy set of rules and regulations to be considered a Permitted Development and not require planning permission.


These rules include but are not limited to:

No more than half the area of land around the “original house” would be covered by additions or other buildings.
No extension to be higher than the highest part of the roof.
Maximum height of a single-storey rear extension of four metres.
No verandas, balconies or raised platforms.

To ensure you are complying with all the appropriate rules, our members will help you every step of the way. All members of the Kent Building Network are experienced in planning permission and the regulatory requirements of all types of glass extensions in Kent. It may be also worth noting that, if your property is leasehold, you will usually need to ask the freeholder’s permission if you wish to make any major changes, which may have a cost attached to it.

How much does a glass extension cost?

For example, if you want to knock down walls to make way for the new glass extension (especially if they are load-bearing walls) then the cost may rise. However, you can expect a glass room extensions= in Kent to cost from £2000 per m² upwards.

Things to consider when planning to build a glass extension

Glass extensions in Kent are a brilliant option for a wide range of homes of various shapes and sizes. Whether you’re in a ground floor apartment block or in an old heritage cottage – it’s highly unlikely that you won’t be able to have a glass extension built on your property. However, there are some things to consider when thinking if a glass extension is right for you.

Glass extensions need to follow the correct building regulations

Modern building regulations require glass extensions in Kent to have quite high levels of thermal efficiency, and it is sometimes a little trickier to have glass extensions comply with this. Even when you plan to use special double or triple-glazed glass, more heat tends to be lost through glass than through a standard, solid extension build.

Do you want a framed or un-framed glass extension?

Although the glass is the star of the show, there are still plenty of design options to consider. Usually, the large panes of glass sit in some kind of frame, and many people want this frame to appear as thin as possible to give the glass extension a really polished, seamless look. When it comes to the glazing that you choose for your glass extension, there will be a number of different coating options on offer. All of these choices will affect the appearance of your new glass extension, so it’s important to consider how this will look. Another element to consider is whether your new glazed panels are going to be fixed, bi-fold windows, or even glass panels that slide open!

Other factors affecting the overall look and design of glass extensions in Kent are things such as whether you are going to have a solid roof or a brise-soleil, – or even a sun shield – to prevent too much sun and heat entering the new glass room.
