Which postcode districts around Tower Hamlets do we cover for modern flat project work?

Every Tower Hamlets postcode district we draw in, the stock that dominates it and the authority that validates a modern flat project there. Tower Hamlets fees below are the statutory England rates for 2026, not modern flat project estimates.

PostcodeAreaDominant stockWhat it means for a modern flat project
E1Whitechapel / SpitalfieldsWarehouse conversions, modern infillA modern flat project at an E1 address in Whitechapel / Spitalfields is determined by Tower Hamlets Council under its own Local Plan policies for Whitechapel / Spitalfields.
E1WWappingGeorgian terraces, warehouse conversionsE1W covers Wapping only; Tower Hamlets Council handles the modern flat project, and Wapping case officers apply the E1W conservation-area map.
E2Bethnal GreenWarehouse conversions, modern infillBethnal Green is split at E2. Either Tower Hamlets Council or Hackney Council can determine a modern flat project here, so the E2 address is checked against both policies maps first.
E3BowVictorian terraces, Georgian fragmentsBow sits wholly inside E3, so Tower Hamlets Council validates every modern flat project submitted from an E3 address.

Which Tower Hamlets neighbourhoods suit a modern flat project best?

Roof pitch, wall build-up and plot depth change every few Tower Hamlets streets, and each one changes what a modern flat project can achieve at that address.

What local planning policy applies to a modern flat project in Tower Hamlets?

Conservation areas covering Tower Hamlets: Tower Hamlets Council runs 58, and Fournier Street, Tredegar Square, Wapping Pierhead are the ones Tower Hamlets owners meet most. A modern flat project inside a Tower Hamlets conservation area loses permitted development, so the Tower Hamlets submission is a householder application at £258 decided in 8 weeks — not a £120 prior approval decided in 6 weeks. In Tredegar Square a modern flat project 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 modern flat project 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.

The building fabric around Tower Hamlets: 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. A modern flat project in Tower Hamlets is scoped against that stock first. Our Tower Hamlets fixed fee starts at £840; the £1,750 Complete package runs the Tower Hamlets scheme through Tower Hamlets Council planning and building control in one go.
