CAN I BUILD A TWO-STOREY EXTENSION WITHOUT PLANNING PERMISSION?
If you’re thinking of adding a two-storey extension to your home but are unsure if you want to tackle the obstacle of planning permission, then this post is for you.
Two-storey extensions are a great way of creating more space for your existing property. Rooms, such as the kitchen can be expanded, making your life easier. Rooms, such as dining areas can be implemented using the extra space gained from an extension.
What makes two-storey extensions great is that as well as adding rooms, such as the ones mentioned above, you can also add an extra bedroom on the second level. Ideal for families and those who like to have guests visit.
You may not have thought it, but two-storey extensions make for greater value for money. The average cost per square metre is reduced as you are building out and up. Most extensions extend only outwards meaning you will have to pay more as you are using up more ground area and often you will need different types of planning permission.
The short answer to the title question is no. You do not require planning permission for a two-storey extension, as long as the extension you’re planning to build, falls within permitted development guidelines/rights.
When it comes to the height of your extension, you must abide by these rules. The eaves and pitch of the new extension must not be higher than the existing house.
The only time this would not be the case, is if your property was within 2 metres of a boundary. Then the maximum height for the eaves would be restricted to 3 metres.
The roof pitch of the new extension should match the existing house pitch as much as possible.
As well as getting the pitch to match the existing home as reasonably possible, all materials used should be similar to that of the house.
With a two-storey extension, you can extend up to 3 metres from the original house. You also must leave, at least, 7 metres from the rear boundary. Keep this in mind when planning out your extension, make sure you have the space to work with.
Another way to look at it is, any extension to the house, shed, or outbuilding should not cover more than 50% of the total land around the house.
When it comes to two-storey extensions, there are a few specific restrictions you should know.
Firstly, if your property is not a house, a flat, for example, you will not have permitted development rights. This doesn’t mean you can’t have an extension built, but it does mean you will need full planning permission. Another thing to add is that if your property is a house conversion, such as a barn conversion, you may not be able to take advantage of permitted development rights.
Another example of properties that will require full planning permission for an extension are properties that are located within a conservation area, such as a national park, the Norfolk or Suffolk Broads, areas of Outstanding Natural Beauty, or World Heritage Sites.
What if your house is listed? “A building is listed when it is of special architectural or historic interest considered to be of national importance and therefore worth protecting”. For buildings such as these, other permissions may be required if you wish to build an extension onto the property. These often require more detail than typical planning permission.
Two-storey extensions are an amazing, cost-effective way of creating more space for your property, with the added bonus that planning permission is often not required.
As discussed, there are a few guidelines and restrictions to watch out for. It’s important to do your research before venturing into a project like this.
