SW11 · Battersea & Clapham Junction
SW11 includes the Battersea Park, Battersea Square, Shaftesbury Park Estate and Heaver Estate conservation areas around Clapham Junction — the 'between the commons' terrace market. Basements are common and controlled by Policy LP6 (multi-level not supported, roughly half of front and back gardens retained).

Real · planning.data.gov.ukWandsworth has 45 designated conservation areas and 0 Article 4 areas. A district is too coarse to say which apply to your house — postcode districts span many streets and designations are drawn street by street.

Is SW11 in a conservation area?
Partly — and which part matters. A postcode district is never uniformly designated: SW11 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 SW11 itself does not fall inside one — but many of its streets will.

Does an Article 4 direction apply in SW11?
The national dataset holds no Article 4 geometry within 1km of the centre of SW11. Treat that as unknown, not as “none”. The national dataset is known to omit property-specific directions, so the only safe answer is to verify on the council's own register for Wandsworth before assuming a permitted-development right still exists.

Do you need planning permission in SW11?
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 |
SW11 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 SW11?
| 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 Wandsworth — 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 →
