Kitchen-diner rear extension in Chigwell
For homes in Chigwell, a kitchen-diner rear extension is often the simplest way to gain space without moving. An open-plan kitchen, dining and family room that opens straight onto the garden. We take it from survey to completion certificate.
We cover Chigwell (IG7, IG9 and IG10) as part of our Essex work. A kitchen-diner is often the reason people in Chigwell extend: the back kitchen in Victorian terraces and 1930s semis is rarely big enough for a table.

Do you need planning permission for a kitchen-diner rear extension in Chigwell?
Here is how the rules in England apply to a kitchen-diner rear extension in Chigwell.
Under England's householder permitted development rules you can usually add 3 metres at the back of an attached house, or 4 metres on a detached house, without a planning application, as long as the extension stays under 4 metres high and its eaves stay under 3 metres where it 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. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Chigwell like to extend?
Chigwell mixes Victorian terraces with 1930s semis, so both side returns and full-width kitchen extensions suit houses here.

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

Yes. Wet underfloor heating in the new screed is the usual choice, often with the old room's radiators kept or replaced.
