E3 primarily covers Bow in Tower Hamlets.
Decisions for E3 are made by Tower Hamlets Council. Standard Permitted Development rules apply for most rear extensions and loft conversions on terraced and semi-detached houses, unless the property is in a conservation area, is listed, or sits under an Article 4 Direction. Article 4 in Tower Hamlets: Yes.
Building regs from £950. We do not charge hourly. Free site survey across all E3 addresses.
From first call to planning decision: typically 12–14 weeks. Site survey week 1, design weeks 2–3, validation 1–2 weeks, statutory 8-week determination. Tower Hamlets Council timelines align with the national norm.
Bow in E3 is characterised by the housing stock of Tower Hamlets — broadly georgian in spitalfields and wapping.

Pick a slot that suits you. No obligation and no sales pressure, just straight answers on your planning route.
Every E3 postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. E3 fees below are the statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
| E3 | Bow | Victorian terraces, Georgian fragments | E3 covers Bow only; Tower Hamlets Council handles the drawing package. |
| E3 | Mile End | Victorian terraces, post-war estates | Mile End sits inside E3; drawing package proposals here are determined by Tower Hamlets Council. |
| E1 | Whitechapel / Spitalfields | Warehouse conversions, modern infill | Adjoining district to E3, also inside Tower Hamlets for drawing package purposes. |
| E1W | Wapping | Georgian terraces, warehouse conversions | Adjoining district to E3, also inside Tower Hamlets for drawing package purposes. |
| E2 | Bethnal Green | Warehouse conversions, modern infill | Adjoining district to E3, also inside Tower Hamlets for drawing package purposes. |
Roof pitch, wall build-up and plot depth change every few E3 streets, and each one changes what a drawing package can achieve at that address.
Conservation areas covering E3 (Bow): Tower Hamlets Council runs 58, and Spitalfields, Whitechapel Market, Fournier Street are the ones E3 (Bow) owners meet most. A drawing package inside a E3 (Bow) conservation area loses permitted development, so the E3 (Bow) submission is a householder application at £548 decided in 8 weeks — not a £249 prior approval decided in 6 weeks. In Tredegar Square a drawing package is judged on the street elevation first.
What Article 4 removes near E3 (Bow): Article 4 for HMOs borough-wide; additional Article 4 covering office-to-residential in Canary Wharf and City Fringe. Before pricing a drawing package we check whether the E3 address is inside the mapped area, because Tower Hamlets Council draws the E3 (Bow) boundary street by street rather than across the whole of E3 (Bow).
The building fabric around E3 (Bow): 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 drawing package in E3 (Bow) is scoped against that stock first, because it decides whether the scheme runs as permitted development, a £274 Lawful Development Certificate, or a full £548 application to Tower Hamlets Council.
