When Planning
Permission is Required

Not all home extensions require planning permission. You may need permission if:

The extension exceeds specific size limits under Permitted Development Rights.

Your home is located in a conservation area or is a listed building.

The extension will significantly alter the appearance or height of your property.

You’re building close to a boundary, affecting neighbours or privacy.

You plan to use the space for non-residential purposes. We assess your property and extension plans to determine if permission is required.
