UK law and planning permission for extensions
The Town and Country Planning Act 1990: Foundation of Planning Permission
Under UK law, most home extensions will require planning permission from the local council. Giving local authorities the power to control development in their area, this is governed by the Town and Country Planning Act 1990.
Permitted Development: Exceptions to the Rule
There are some exceptions to this rule, however. The Town and Country Planning (General Permitted Development) (England) Order 2015 sets out the criteria for “permitted development.” This is development that can be carried out without the need for planning permission. Furthermore, permitted development rights allow certain types of development to be carried out without the need for an application for planning permission, subject to certain conditions and limits.
Criteria for Permitted Development: Size, Type, and Location
The specific criteria for permitted development vary depending on the location and type of extension. Generally these include considerations such as size limits and distance from the property boundary. For example, single-story rear extensions are generally allowed under permitted development rights as long as they do not extend more than four meters beyond the rear wall of the original house for a detached house, or more than three meters for any other type of house.
Consulting Local Councils: Navigating Planning Permission
If you are planning to build an extension and are not sure whether you need planning permission, it’s a good idea to check with your local council. They will be able to provide you with information on the specific requirements and any exceptions that may apply to your extension.
Building Regulations: Ensuring Safety and Standards
It is also worth noting that even if your extension is classified as a permitted development, you may still need to apply for building regulations approval. Additionally, building regulations ensure that the extension is built to certain standards and is safe and wearable. This is governed by the Building Act 1984 and the Building Regulations 2010.
