Answers for Tower Hamlets

Does Tower Hamlets have an Article 4 Direction?

Yes — Article 4 for HMOs borough-wide; additional Article 4 covering office-to-residential in Canary Wharf and City Fringe.

What does Article 4 remove?

Article 4 removes specific Permitted Development rights — typically the right to convert a single dwelling (C3) to an HMO (C4), or office (B1) to residential (C3), without full planning permission. The right is removed only where the Direction applies.

Can I still extend my home in Tower Hamlets under Article 4?

Yes. Article 4 in most London boroughs targets HMO conversions and office-to-residential, not householder extensions. Standard rear extensions and loft conversions remain available under Permitted Development unless your property is in a conservation area or is listed.

How do I check if my address is covered by Article 4 in Tower Hamlets?

Check the planning portal at Tower Hamlets Council or call us — we look up the Article 4 status for your specific address before quoting.

What happens if I build under PD when Article 4 applies?

If Article 4 applies and you build without planning, you face enforcement action: a retrospective application, a stop notice, or in serious cases an enforcement notice requiring reversal. Always check before starting.

Conservation areas covering Tower Hamlets: Tower Hamlets Council runs 58, and Wapping Pierhead, Spitalfields, Whitechapel Market are the ones Tower Hamlets owners meet most. A scheme inside an Article 4 area inside a Tower Hamlets conservation area loses permitted development, so the Tower Hamlets submission is a householder application at £548 decided in 8 weeks — not a £249 prior approval decided in 6 weeks. In Fournier Street a scheme inside an Article 4 area is judged on the street elevation first.

Tower Hamlets and Article 4: Article 4 for HMOs borough-wide; additional Article 4 covering office-to-residential in Canary Wharf and City Fringe.

Tower Hamlets housing stock: Georgian in Spitalfields and Wapping; Victorian industrial conversions; extensive post-war social housing; modern high-density towers in Canary Wharf and Aldgate.
