Single-storey rear extensions, lofts and side extensions you can build in Newham without full planning — and the exceptions.
Enforcement, more readily than in most boroughs. Newham issued 209 enforcement notices in twelve quarters, the fifth highest count in London, against 1,313 householder decisions. On the larger extension route it granted 25 and refused 70, a 26.3% grant rate below London’s 34.6%.

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 Newham postcode district we draw in, the stock that dominates it and the authority that validates a permitted development scheme there. Newham 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 |
|---|---|---|---|
| E6 | East Ham / Beckton | Victorian terraces | East Ham / Beckton sits wholly inside E6, so Newham Council validates every permitted development scheme submitted from an E6 address. |
| E7 | Forest Gate | Victorian terraces | Forest Gate sits wholly inside E7, so Newham Council validates every permitted development scheme submitted from an E7 address. |
| E12 | Manor Park | Victorian terraces | Manor Park is split at E12. Either Newham Council or Redbridge Council can determine a permitted development scheme here, so the E12 address is checked against both policies maps first. |
| E13 | Plaistow | Victorian terraces, post-war flats | Plaistow sits wholly inside E13, so Newham Council validates every permitted development scheme submitted from an E13 address. |
| E15 | Stratford / West Ham | New-build, post-war estates | Stratford / West Ham sits wholly inside E15, so Newham Council validates every permitted development scheme submitted from an E15 address. |
| E16 | Canning Town / Royal Docks | Post-war estates, new-build | Canning Town / Royal Docks sits wholly inside E16, so Newham Council validates every permitted development scheme submitted from an E16 address. |
| E20 | Olympic Park / East Village | Victorian terraces across West Ham | E20 covers Olympic Park / East Village only; Newham Council handles the permitted development scheme. |
Roof pitch, wall build-up and plot depth change every few Newham streets, and each one changes what a permitted development scheme can achieve at that address.
Newham conservation designations: there are 10 across Newham Council, Plaistow, West Ham, Manor Park among them. Designation costs a Newham owner the permitted-development route: a permitted development scheme then needs a £548 householder application over 8 weeks, in place of the £249 prior approval route that takes 6 weeks. West Ham is the Newham designation that most often changes a permitted development scheme design.
Article 4 and your Newham permitted development scheme: Article 4 Direction requires planning permission for any HMO conversion, plus restrictions on office-to-residential in Stratford and Royal Docks. At a E6 address that matters twice over, because Newham Council applies the direction unevenly across Newham — we read the Newham policies map for the exact E6 address before quoting permitted development schemes.
The building fabric around Newham: Victorian terraces across West Ham, Forest Gate, Plaistow; Olympic-era new-build in Stratford; post-war in Canning Town; substantial ongoing regeneration. High-regeneration borough; Olympic Park and Royal Docks drive major development; heavily HMO-managed borough. A permitted development scheme in Newham is scoped against that stock first.
