Do you need planning permission for a kitchen-diner rear extension in Richmond?
Here is how the rules in England apply to a kitchen-diner rear extension in Richmond.
English permitted development (Class A) allows a single-storey rear extension of 3 metres on a terraced or semi-detached house and 4 metres on a detached one, measured from the original house, with a maximum height of 4 metres and eaves of no more than 3 metres within 2 metres of a boundary.
If 3 or 4 metres is not enough, England's prior approval route allows 6 metres on a terraced or semi-detached house and 8 metres on a detached house for a single-storey rear extension. Neighbours are consulted, the council decides within 42 days, and the fee is £249, rising to £310 from 8 December 2026.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. At the first visit we measure what is there now and tell you which route fits: permitted development, prior approval or a planning application.
What are homes in Richmond like to extend?
Much of Richmond is Victorian and Edwardian terraced housing with narrow back additions, which suits side returns, wraparounds and 3 metre rear extensions. Many streets are in conservation areas, gardens are short, and almost everything comes through the house or along a rear alley.

FAQ
Kitchen-diner rear extension questions in Richmond
Who will build my extension?
Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.
Is the site visit in Richmond free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.

Often. A narrow utility or boot room along one side keeps the washing machine out of the open-plan space.

Can you match the brick or stone on my Richmond house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.

Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
