Frequently Asked Questions

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 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 build a wraparound extension without planning permission?

Wraparound extensions often exceed permitted development limits and usually require planning approval.

Can I extend above a single-storey extension?

Possibly, but this often requires planning permission and must comply with height and design considerations.

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.

What is prior approval neighbour consultation?

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