What Article 4 restricts in Tower Hamlets, how it affects extensions, lofts and HMOs, and how to plan around it.
Yes — Article 4 for HMOs borough-wide; additional Article 4 covering office-to-residential in Canary Wharf and City Fringe.
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.
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.
Check the planning portal at Tower Hamlets Council or call us — we look up the Article 4 status for your specific address before quoting.
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.

Every Tower Hamlets postcode district we draw in, the stock that dominates it and the authority that validates a scheme inside an Article 4 area there. Tower Hamlets fees below are the statutory England rates for 2026, not scheme inside an Article 4 area estimates.
| Postcode | Area | Dominant stock | What it means for a scheme inside an Article 4 area |
|---|---|---|---|
| E1 | Whitechapel / Spitalfields | Warehouse conversions, modern infill | A scheme inside an Article 4 area at an E1 address in Whitechapel / Spitalfields is determined by Tower Hamlets Council under its own Local Plan policies for Whitechapel / Spitalfields. |
| E1W | Wapping | Georgian terraces, warehouse conversions | Wapping sits wholly inside E1W, so Tower Hamlets Council validates every scheme inside an Article 4 area submitted from an E1W address. |
| E2 | Bethnal Green | Warehouse conversions, modern infill | E2 straddles a boundary: Bethnal Green addresses fall to Tower Hamlets Council or Hackney Council, so confirm which authority validates the scheme inside an Article 4 area before submitting E2 drawings. |
| E3 | Bow | Victorian terraces, Georgian fragments | A scheme inside an Article 4 area at an E3 address in Bow is determined by Tower Hamlets Council under its own Local Plan policies for Bow. |
| E14 | Canary Wharf / Poplar / Limehouse | Modern apartments | E14 covers Canary Wharf / Poplar / Limehouse only; Tower Hamlets Council handles the scheme inside an Article 4 area. |
Roof pitch, wall build-up and plot depth change every few Tower Hamlets streets, and each one changes what a scheme inside an Article 4 area can achieve at that address.
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. A scheme inside an Article 4 area planned at a E1 address is checked against that direction first; Tower Hamlets Council publishes the Tower Hamlets extent, and the E1 line rarely follows the Tower Hamlets boundary you would expect.
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. High heritage value in pockets (Spitalfields, Wapping), mixed with substantial regeneration areas; active planning committee. Read that before choosing a scheme inside an Article 4 area route in Tower Hamlets — construction, not postcode, sets what is achievable.
