Single-storey rear extensions, lofts and side extensions you can build in Tower Hamlets without full planning — and the exceptions.
Sometimes, but the borough decides few householder cases at all — 563 in twelve quarters. It recorded 10 larger-extension grants against 5 refusals, too few for a published rate, and carries 63 Article 4 areas and 969 listed buildings. It issued 399 certificates.

In detailSingle-storey rear extension up to 3m deep (attached house) or 4m (detached); side extension up to half the original width; loft conversion up to 40m³ (terraced) or 50m³ (semi-detached); single-storey outbuilding within the curtilage; replacement windows and doors. All subject to material match, eaves setback (20cm), and not facing a highway.
No. Permitted Development rights apply only to houses (Class C3 dwellings). Flats and maisonettes require full planning for almost every external alteration.
Yes — significantly reduced. In a conservation area: side extensions and two-storey rear extensions are not PD; cladding is not PD; chimney removal needs planning; roof additions are restricted.
An LDC is a formal confirmation from the council that your proposal is lawful PD — recommended before building, useful when selling. Costs around £103 for council fees + drawings.
Yes. Building regulations are entirely separate from planning. Permitted Development removes the planning requirement only — you still need building control sign-off for structure, insulation, fire safety, drainage, and ventilation. We deliver both planning and building regs drawings.

Every Tower Hamlets postcode district we draw in, the stock that dominates it and the authority that validates a permitted development scheme there. Tower Hamlets fees below are the statutory England rates for 2026, not permitted development scheme estimates.
| Postcode | Area | Dominant stock | What it means for a permitted development scheme |
|---|---|---|---|
| E1 | Whitechapel / Spitalfields | Warehouse conversions, modern infill | A permitted development scheme 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 permitted development scheme submitted from an E1W address. |
| E2 | Bethnal Green | Warehouse conversions, modern infill | A permitted development scheme in Bethnal Green may land with Tower Hamlets Council or Hackney Council — E2 crosses the boundary, and the E2 policies map decides it street by street. |
| E3 | Bow | Victorian terraces, Georgian fragments | E3 covers Bow only; Tower Hamlets Council handles the permitted development scheme. |
| E14 | Canary Wharf / Poplar / Limehouse | Modern apartments | E14 covers Canary Wharf / Poplar / Limehouse only; Tower Hamlets Council handles the permitted development scheme. |
Roof pitch, wall build-up and plot depth change every few Tower Hamlets streets, and each one changes what a permitted development scheme can achieve at that address.
Conservation areas covering Tower Hamlets: Tower Hamlets Council runs 58, and Whitechapel Market, Fournier Street, Tredegar Square are the ones Tower Hamlets owners meet most. A permitted development scheme 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 permitted development scheme is judged on the street elevation first.
Article 4 and your Tower Hamlets permitted development scheme: Article 4 for HMOs borough-wide; additional Article 4 covering office-to-residential in Canary Wharf and City Fringe. At a E1 address that matters twice over, because Tower Hamlets Council applies the direction unevenly across Tower Hamlets — we read the Tower Hamlets policies map for the exact E1 address before quoting permitted development schemes.
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 permitted development scheme route in Tower Hamlets more than the postcode does.
