E1 primarily covers Whitechapel / Spitalfields in Tower Hamlets.
Decisions for E1 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. Site survey across all E1 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.
Whitechapel / Spitalfields in E1 is characterised by the housing stock of Tower Hamlets — broadly georgian in spitalfields and wapping.

Every E1 postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. E1 fees below are the statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
| E1 | Whitechapel / Spitalfields | Warehouse conversions, modern infill | A drawing package at an E1 address in Whitechapel / Spitalfields is determined by Tower Hamlets Council under its own Local Plan policies for Whitechapel / Spitalfields. |
| E1 | Spitalfields | Georgian listed townhouses | Spitalfields sits inside E1; drawing package proposals here are determined by Tower Hamlets Council. |
| E1 | Whitechapel | Victorian terraces, post-war estates, new-build | Whitechapel sits inside E1; drawing package proposals here are determined by Tower Hamlets Council. |
| E1 | Mile End | Victorian terraces, post-war estates | Mile End sits inside E1; drawing package proposals here are determined by Tower Hamlets Council. |
| E1 | Shadwell | Georgian fragments, post-war estates | Shadwell sits inside E1; drawing package proposals here are determined by Tower Hamlets Council. |
| E1 | Stepney | Victorian terraces, post-war estates | Stepney sits inside E1; drawing package proposals here are determined by Tower Hamlets Council. |
| E1W | Wapping | Georgian terraces, warehouse conversions | Adjoining district to E1, also inside Tower Hamlets for drawing package purposes. |
| E2 | Bethnal Green | Warehouse conversions, modern infill | Adjoining district to E1, also inside Tower Hamlets for drawing package purposes. |
| E3 | Bow | Victorian terraces, Georgian fragments | Adjoining district to E1, also inside Tower Hamlets for drawing package purposes. |
Roof pitch, wall build-up and plot depth change every few E1 streets, and each one changes what a drawing package can achieve at that address.
E1 (Whitechapel / Spitalfields) conservation designations: there are 58 across Tower Hamlets Council, Tredegar Square, Wapping Pierhead, Spitalfields among them. Designation costs a E1 (Whitechapel / Spitalfields) owner the permitted-development route: a drawing package then needs a £548 householder application over 8 weeks, in place of the £249 prior approval route that takes 6 weeks. Spitalfields is the E1 (Whitechapel / Spitalfields) designation that most often changes a drawing package design.
E1 (Whitechapel / Spitalfields) and Article 4: Article 4 for HMOs borough-wide; additional Article 4 covering office-to-residential in Canary Wharf and City Fringe. A drawing package planned at a E1 address is checked against that direction first; Tower Hamlets Council publishes the E1 (Whitechapel / Spitalfields) extent, and the E1 line rarely follows the E1 (Whitechapel / Spitalfields) boundary you would expect.
E1 (Whitechapel / Spitalfields) 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 drawing package route in E1 (Whitechapel / Spitalfields) — construction, not postcode, sets what is achievable. Tower Hamlets Council charges £548 for a householder application and has 8 weeks to determine it.
