Hackney has a strong stock of Victorian and Edwardian terraced houses and a growing number of conservation areas that reflect its 19th-century character. The council's Residential Extensions and Alterations SPD (December 2025) is the key reference document for most domestic proposals. Hackney is generally a pragmatic authority — it applies the standard PD rules and its own SPD, but is less restrictive than the Royal Borough of Kensington and Chelsea or Camden in most situations.
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 Hackney.
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.
Basement proposals are highly site-specific. Always validate with an address-level check and professional advice.
Check my propertyCouncils 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.

Search the address, choose your project type, and get an answer based on permitted development rules, local constraints, and nearby precedent decisions.
Not always. Many rear extensions on Hackney's Victorian terraces fall within permitted development rules for houses — but the extension must stay within the PD size limits and the property must not be in a conservation area with specific controls, a flat, or subject to Article 4 directions. Check your address first.
It can be. A rear dormer on a house that stays within the 50 cubic metre volume limit, doesn't front a highway, and doesn't alter the ridgeline may fall within PD. Conservation area properties and any front-facing changes typically need full planning permission.
The Residential Extensions and Alterations SPD sets design expectations beyond the basic PD limits — things like the 45-degree rule for overlooking, appropriate materials, and roof design. Even if your project is within PD size limits, the SPD guides what the council expects to see in a formal application.
Hackney's planning portal and GIS mapping tool show conservation areas, listed buildings, and Article 4 directions. The CanUBuild checker can also search your address and show relevant constraints plus nearby approved and refused applications.
