What you can usually build
Common projects that may be straightforward when they fit within PD limits and local constraints.
Tower Hamlets is one of London's most architecturally diverse boroughs, from the Georgian streets of Spitalfields (home to many Grade I and II* listed buildings) to Canary Wharf and the residential streets of Stepney, Bow, and Mile End. The council has significant conservation area coverage in its western parts and Article 4 directions for HMOs in several wards. Regeneration activity along the Crossrail corridor and in Whitechapel is ongoing.
Common projects that may be straightforward when they fit within PD limits and local constraints.
These are the usual reasons planning permission becomes more likely in Tower Hamlets.
The biggest drivers of approval are the exact proposal (dimensions and design) and the exact site constraints (designation, conditions, neighbour impacts). Use borough context as a starting point, then validate it with address-level checks and nearby precedents.
Projects that stay modest in size, match materials, and avoid obvious neighbour impacts are more likely to be straightforward — even before you consider borough-specific policies.
Conservation areas, listed buildings, Article 4 directions, flood risk and TPOs can flip the answer. Address-level checks stop you wasting money on the wrong scheme.
The fastest signal is what the council has approved or refused on comparable streets nearby. Precedent does not guarantee success, but it helps you shape a lower-risk design.
Councils rarely refuse the "idea" of an extension or loft conversion — refusals are usually about scale, design, neighbour impacts, and policy/designation conflicts. When you run a check, CanUBuild shows nearby approvals and refusals so you can see what has worked locally.
An invalid application cannot be registered. Use this checklist to ensure your submission is complete before you pay the fee.
Requirements can change — always verify the current validation checklist on the Tower Hamlets Council website before submitting.
Search the address, choose your project type, and get an answer based on permitted development rules, local constraints, and nearby precedent decisions.
If the property is listed — which covers many of the Georgian terraces in Spitalfields — yes, listed building consent is required for any works that affect the character of the building, including internal alterations. Works without consent are a criminal offence.
Possibly — many properties in Mile End and Bow are not in conservation areas and benefit from standard permitted development rights. Check the specific constraints at your address, including whether any Article 4 directions apply.
Whitechapel is the subject of ongoing regeneration and has a number of opportunity area designations. For typical domestic extensions, the relevant constraints are whether the property is in a conservation area, and whether any Article 4 directions apply.
Householder applications should be determined within 8 weeks. The borough is busy and active pre-application engagement on complex or sensitive proposals is recommended to avoid delays.
