Rear extension drawings in Worcester Park KT4
A rear extension on a Worcester Park house that is not detached can go back 3 metres under permitted development, or 6 metres with the council's prior approval. DrawingsDirect draws rear extensions in KT4 from £695. Which route suits you depends on your neighbours and on how the council has treated deeper schemes.

3 metres or 6 metres: the two rear extension limits
A single-storey rear extension on a house other than a detached one may extend up to 3 metres beyond the rear wall of the original house under permitted development. A larger home extension, which needs the council's prior approval, can extend up to 6 metres on the same type of house (GPDO 2015, Schedule 2, Part 1, Class A, on legislation.gov.uk).
Our permitted development explainer lists what else the rules require, and the prior approval glossary entry explains how the larger-extension route differs from a planning application.
Which council covers your Worcester Park address?
KT4 straddles a council boundary: some addresses fall under Kingston and some under Sutton. Check your council tax bill or the postcode checker on either council's website before you read any local figures.
The figures on this page are Kingston's. If your house is on the Sutton side, our rear extension page for Cheam SM3 carries the Sutton record instead.
Our analysis of the MHCLG Planning Data Platform finds 28 live conservation-area entries on the national register for Kingston (bulk snapshot retrieved 14 Aug 2026).
Kingston's record on 6 metre extensions
In the eight quarters to 2026 Q2, Kingston determined 110 larger home extension prior approvals and granted 10% of them (our analysis of MHCLG planning application statistics, table PS1). Notifications where the council decided prior approval was not needed are outside those counts, so 10% is not the share of all deep extensions that go ahead.
It does show that when Kingston examines a deep rear extension closely, the result has mostly been a refusal. We look at the neighbouring houses before recommending the 6 metre route, and we promise no outcome.
Householder decisions in Kingston
Kingston decided 742 householder applications in the four quarters to 2026 Q2, including prior approvals, and granted 83% of them (our analysis of MHCLG planning application statistics, table PS2).
A scheme that goes beyond permitted development, such as a deeper extension, a kitchen extension that also takes in a side return, or one with a first floor, goes through that householder route. Our kitchen extension drawings page covers the room-led view of the same project.
Conservation areas and Article 4 directions near KT4
Our analysis of the MHCLG Planning Data Platform finds 28 live conservation-area entries on the national register for Kingston (bulk snapshot retrieved 14 Aug 2026). For the KT4 postcode district alone, our analysis of the Article 4 direction area dataset finds 2 live register rows within a small envelope around the district centre (retrieved 15 Oct 2026). The register is incomplete, so treat that as a lower bound.
Not every Article 4 direction touches extensions, but one that does can remove the permitted development rights the 3 and 6 metre limits rely on. Ask the council whether one covers your road and which rights it removes, and read our Article 4 direction guide for what to ask.
