Frequently Asked Questions

Can I build over a sewer?

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

Does an Article 4 Direction affect my extension plans?

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

Do I need prior approval for a larger extension?

In some cases, larger home extensions require a prior approval process where neighbours are notified and the council assesses certain impacts.

Can I extend a house that has already been extended?

Permitted development limits are cumulative, so previous extensions may reduce what is still allowed.

Does building regulations approval still apply?

Yes. Even if planning permission is not required, building regulations approval is usually still necessary.

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

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