Do You Need Planning Permission For a Single Storey Extension?
Planning Permission For a Single Storey Extension
Does a single storey extension require planning permission? In many instances, an extension to your home is considered to be a permitted development.
If this is the case for your extension, no applications or permission would be required.
However, your single storey extension will be subject to certain limits and criteria so it is highly recommended you seek professional advice or visit the Government’s Planning Portal for more advice.
Permitted Planning Permission Criteria For a Single Storey Extension
- Extension size can be no more than half the area of land around original house.
- The extension cannot be built under the permitted development rules if it near a public highway either by way of front elevation or side.
- The extension can be no higher than the highest part of the roof.
- It must not extend beyond the rear wall of the original house by more than three metres for a semi-detached home and four metres for a detached home.
- The maximum height for a single storey rear extension should be four metres.
- The eaves and ridge should be no higher than the existing house.
- Side extensions must be single storey, with a maximum height of four metres and a width no more than half that of the original house.
- Materials used for the extension should be similar in appearance to the existing home.
If you want to build an extension with more than one storey, you’ll likely have to get planning permission.
That’s because more rules are governing these builds, particularly when it comes to height. For example, you can’t build an extension higher than your house, and you can’t add any balconies or verandas without permission either.
Planning permission for a single storey extension is actually just one consent that may be required before building takes place.
Planning laws are subject to change, as are building regulation requirements. If you intend to further extend your property, it’s important you check these.
