Kitchen and house extension drawings in Chessington, KT9
A single-storey kitchen extension on a Chessington semi or terrace can go 3 metres back without a planning application, or up to 6 metres if Kingston gives prior approval (GPDO 2015, Schedule 2, Part 1, Class A). Anything bigger goes to the council as a householder application. We draw all three routes, with rear extension drawings from £695.

Kitchen extensions: the shapes we draw in Chessington
A kitchen extension usually means pushing the back of the house out, adding a side-return infill, or both. Owners who need more bedrooms alongside the kitchen sometimes add a storey above, which is a bigger application.
We draw each of these, and our pages on kitchen extension drawings, side return extensions and double-storey extensions show what each set contains.
How Kingston decides extension applications
The Royal Borough of Kingston upon Thames decided 742 householder applications in the four quarters to 2026 Q2 and granted 83% (our analysis of MHCLG planning application statistics, table PS2). KT9 is mostly in Kingston, though check your address, as postcode boundaries and council boundaries do not always match.
Deeper kitchens on the prior approval route are a different story. Over the eight quarters to 2026 Q2 Kingston found prior approval was required on 110 larger home extension notifications and granted 10% of those (our analysis of MHCLG planning application statistics, table PS1). That excludes every case Kingston waved through as needing no prior approval. Once Kingston looks closely at a deep extension, refusal has been the usual result, so for a kitchen that must go beyond 3 metres we weigh a householder application as well.
A householder application for an extension costs £548 in statutory fee, and a prior approval for a larger rear extension costs £249, both from 1 April 2026.
Permitted development depth, and when Article 4 removes it
Those 3 and 6 metre depths apply to a house that is not detached and assume the permitted development rights are still in place.
An Article 4 direction can take those rights away. The government's planning data register shows at least 8 live Article 4 entries around the KT9 area, and the register is incomplete, so treat that as a minimum (our analysis of the MHCLG Planning Data Platform article-4-direction-area dataset). The same national register holds 28 conservation-area entries for Kingston (our analysis of the MHCLG Planning Data Platform conservation-area dataset), and the conservation area map on Kingston's website shows whether a Chessington street is inside one. Our Article 4 direction guide explains how to find out whether your road is affected, and you can search the government's Article 4 dataset yourself.
Costs: statutory fees and our drawings
A householder application for an extension costs £548 in statutory fee, and a prior approval for a larger rear extension costs £249, both from 1 April 2026. Our rear extension drawings are priced from £695. The rear extension cost guide covers build costs, which are a separate budget.
