Do you need planning permission for a kitchen-diner rear extension in Headstone?
Here is how the rules in England apply to a kitchen-diner rear extension in Headstone.
In England a single-storey rear extension can often be built under permitted development: up to 3 metres beyond the original rear wall of an attached house, or 4 metres on a detached house, no higher than 4 metres, with eaves no higher than 3 metres if any part is within 2 metres of a boundary.
England also has the larger home extension route: a single-storey rear extension of up to 6 metres on an attached house or 8 metres on a detached house, after prior approval from the council. The council notifies your neighbours and has 42 days to decide; the fee is £249 (£310 for applications made from 8 December 2026). The route is not available on designated land such as conservation areas.
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 Headstone like to extend?
Much of Headstone is 1920s and 1930s semis and short terraces with longer gardens than inner London, which suit full-width single-storey rear extensions. Parking suspensions, skip licences and controlled hours on residential streets shape the programme more than the build itself.

FAQ
Kitchen-diner rear extension questions in Headstone

Including HA1, HA2 and HA3, and the surrounding Greater London area.
Do you handle building control in Headstone?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.

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