Frequently Asked Questions

Can I extend a semi-detached house differently to a detached house?

Yes, size limits and projection distances differ depending on property type.

Can I extend a listed building?

Listed buildings require listed building consent, even for minor works. Permitted development rights typically do not apply.

Does permitted development apply to HMOs?

Some permitted development rights may be restricted depending on property use class.

Is there a limit on total site coverage?

Yes. Extensions and outbuildings combined must not cover more than 50% of the curtilage of the original house.

Can I build over a sewer?

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

What happens if I build without permission?

The council may take enforcement action requiring alterations or removal of unauthorised works.
