Kitchen-diner rear extension in Cheshunt
An open-plan kitchen, dining and family room that opens straight onto the garden. We design, get the approvals for and build kitchen-diner rear extensions in Cheshunt and the surrounding area, with one contract from the first survey to building control sign-off.
We cover Cheshunt (EN7, EN8 and EN10) as part of our Hertfordshire work. For Cheshunt kitchens we plan the extraction route and the island drainage before the slab is poured, so nothing has to be chased in later.

Do you need planning permission for a kitchen-diner rear extension in Cheshunt?
Planning for a kitchen-diner rear extension in Cheshunt follows the English householder rules.
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. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.
What are homes in Cheshunt like to extend?
Cheshunt mixes Victorian terraces with 1930s semis, so both side returns and full-width kitchen extensions suit houses here.
