SE24 · Herne Hill
SE24 centres on Herne Hill — the Herne Hill and Poet's Corner conservation areas and the Brockwell Park fringe, shared with Southwark. Edwardian and Victorian houses support lofts and rear extensions; conservation designation shapes the dormer and materials decisions.

Constraint context · Lambeth
Real · planning.data.gov.ukLambeth has 62 designated conservation areas and 12 Article 4 areas. A district is too coarse to say which apply to your house — postcode districts span many streets and SE24 crosses 2 boroughs.

Is SE24 in a conservation area?
Partly — and which part matters. A postcode district is never uniformly designated: SE24 contains 11 conservation areas within 1km of its centre, and whether your own property sits inside one decides whether permitted development survives. The centre point of SE24 itself does not fall inside one — but many of its streets will.

Does an Article 4 direction apply in SE24?
Yes — SE24 has 11 Article 4 directions mapped within 1km of its centre. An Article 4 direction withdraws specific permitted-development rights on the streets it covers, which is the most common reason a project that looks like permitted development turns out to need a full application. The centre point of SE24 does not fall inside one, but coverage is street-level — verify your own address.

Do you need planning permission in SE24?
Three routes exist, and which one you are on is decided by your address, not your postcode district:
| Permitted development — no application. The work stays inside the GPDO limits and no designation removes them. A Lawful Development Certificate is cheap proof for a future buyer. | No permission |
| Prior approval — the larger single-storey rear extension route, with neighbour consultation. Not available on designated land. | 42 days |
| Full householder application — required once a designation removes your permitted-development right, or the scheme exceeds the limits. | 8 weeks |
SE24 contains mapped conservation-area or Article 4 geometry, so a meaningful share of its streets will have lost some permitted-development rights — which pushes those properties onto the full-application route. Whether yours is one of them is an address-level question, not a district-level one.
What does planning permission cost in SE24?
| Householder planning application | £548 (from 1 April 2026) |
| Lawful Development Certificate — proposed works | £274 (half the application fee) |
| Lawful Development Certificate — existing works | £548 (the full application fee) |
| Listed building consent | No fee |
| Resubmission after a refusal | Free once, within 12 months of the decision |
National statutory figures for England — councils do not set them, so they are the same in every borough. Planning fees re-index every 1 April; confirm the current amount on the Planning Portal fee calculator before you apply. These are the council's fees only — drawings, surveys and any specialist reports are separate.
How long does it take?
| Householder application — statutory target | 8 weeks |
| Householder application — in practice | 8–12 weeks |
| Prior approval (larger home extension) | 42 days |
| Lawful Development Certificate | 8 weeks |
| Householder appeal — deadline to lodge | 12 weeks from the decision date |
| Householder appeal — typical decision | Around 18 weeks |
What if it's refused?
A refusal is a decision notice with reasons attached, and those reasons are a roadmap. Most homeowners in Lambeth — as anywhere in England — are better served by amending the scheme and using the free resubmission than by appealing: you get one further application on the same site within 12 months without paying again.
| Who can appeal | The applicant only — not neighbours |
| Fee to appeal | None — you bear your own costs |
| Procedure | Written representations for most householder appeals |
| Success rate | Roughly a third — about 36% of householder appeals allowed in 2025/26 |
Appeals go to the Planning Inspectorate, an independent national body. How to read a refusal and choose your route →
