Frequently Asked Questions

What is the 45-degree rule?

The 45-degree rule is a guideline used by some councils to assess impact on neighbouring properties, particularly in relation to light and outlook.

Can I extend a flat under permitted development?

Flats and maisonettes generally do not benefit from permitted development rights for extensions.

What is the maximum rear projection allowed?

Detached houses may extend up to four metres under standard rules, or eight metres with prior approval. Smaller limits apply to other house types.

Can I extend a listed building?

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

Can I build over a sewer?

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

Can I build a two-storey extension without planning permission?

Two-storey extensions are sometimes permitted, but stricter limits apply to height, rear projection distance, and window placement to avoid overlooking neighbours.
