Frequently Asked Questions

How high can my extension be?

Height limits vary, but rear extensions under permitted development generally cannot exceed four metres for detached houses or three metres for others.

How close can I build to my neighbour’s boundary?

Extensions built close to a boundary must meet height and eaves restrictions, especially if within two metres of the boundary.

What is prior approval neighbour consultation?

For larger extensions, councils notify neighbours and assess specific impacts before granting prior approval.

Does an Article 4 Direction affect my extension plans?

Yes. Article 4 Directions remove certain permitted development rights, meaning planning permission may be required.

What happens if permitted development rights have been removed?

If rights have been removed by planning condition or Article 4 Direction, you will likely need to submit a full planning application before building.

Can I build over a sewer?

Building near or over a public sewer may require a build-over agreement from the relevant water authority.
