Can I extend my house?
You may need to make a planning application if you want to:
- build anything new
- alter the external appearance of the building such as an extension
- carry out other works and operations
- change the use of all or part of your building
Rules, known as ‘permitted development rights’ allow you to extend a house without needing to apply for planning permission if specific limitations and conditions are met.
Outside of the permitted development, you may need to make a planning application. For further guidance, please visit the Planning Portal. You can view advice on planning rules for a range of common projects, such as windows, extensions and energy efficiency measures and use its interactive guides.
If you require further advice before making a planning application, please find out about the pre-application services we offer.
How can I confirm that my project is permitted development and does not require planning permission?
If you believe that the extension/ alteration to your property would not require planning permission, because it would be permitted development, you can seek confirmation of this from us. You would need to submit an application or a Lawful Development Certificate.
This would provide written confirmation as to whether the proposal is considered permitted development for which express planning permission from us would not be required.
