What changes about a rear dormer in each part of Tower Hamlets?

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

• Bow (E3) — a rear dormer in Bow starts from victorian terraces, georgian fragments, and Bow reads as Victorian terraces, Georgian fragments. A dormer on a Georgian roof has to sit behind the parapet line to stand any chance of consent in E3. Tower Hamlets Council assesses Bow rear dormers against its own Bow character guidance, and the location plan we draw for Bow references Bow Bells.
• Mile End (E1, E3) — Victorian terraces, post-war estates defines Mile End, where victorian terraces, post-war estates set what a rear dormer can do. Full-width rear dormers on Victorian terraces here are the default across E1. Any Mile End rear dormer is validated by Tower Hamlets Council, with Mile End Park the usual Mile End reference point on the site plan.

What local planning policy applies to a rear dormer in Tower Hamlets?

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 rear dormer 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 Tredegar Square a rear dormer is judged on the street elevation first.

What Article 4 removes near Tower Hamlets: Article 4 for HMOs borough-wide; additional Article 4 covering office-to-residential in Canary Wharf and City Fringe. Before pricing a rear dormer we check whether the E1 address is inside the mapped area, because Tower Hamlets Council draws the Tower Hamlets boundary street by street rather than across the whole of Tower Hamlets.

What Tower Hamlets is built from: 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. That mix decides the rear dormer route in Tower Hamlets more than the postcode does.
