Carrying out extensive alterations to existing buildings often requires planning permission. Whilst other less prominent changes are typically considered as Permitted Development, meaning you don’t require official planning permission.
If you’re making changes to your home or commercial building, how do you know if you will actually require consent for your local planning authority to carry out the building work?
The bottom line
As Homebuilding and Renovating advises, any work which involves the building of a new property, whether it’s building it from the start or a subdivision, requires planning permission. Extensions to existing buildings and creating new outbuildings, may need planning permission, depending on the size of the project. Providing more modest extensions follow a stringent set of rules, they will fall under the Permitted Development rights category.
Permitted Development Rights
Permitted Development was introduced as part of the Town and Planning Act in 1948 and has remained at the heart of planning permission and development ever since.
Permitted Development essentially enables minor improvements to be made to a property, such as modest extensions or attic conversions, without having to go down the planning system route.
Though it is important to be aware that the work conducted on projects with Permitted Development can vary. Various components such as the location of the property and whether the work will be carried out in conservation areas of national parks, will require different building rules.
Some of the key rules regarding a construction project that does not require a planning permission application as it would be considered a Permitted Development, include:
- No more than half of the land belonging to the property will be used for outbuildings and other additions
- The extension is not forward of the principle elevation or side elevation fronting a road
- The extension is not taller than the highest point on the roof
- A single-storey extension to the rear of the property is not allowed to extend beyond the rear wall of the house by more than three metres on an attached property. If the property is detached, the extension must not extend more than four metres beyond the rear wall
- The maximum height for a rear extension, single-storey extension is four meters
Planning regulation is complex and it is important that if you are planning to extend your home or a commercial property, you are correctly informed on the permission the project will require.
If you are in any doubt about planning permission, it is important to seek advice prior to beginning the project.
