Kitchen-diner rear extension in Cinderford
For homes in Cinderford, 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 Cinderford (GL14 and GL17) as part of our Gloucestershire work. A kitchen-diner is often the reason people in Cinderford extend: the back kitchen in stone and rendered houses is rarely big enough for a table.

Do you need planning permission for a kitchen-diner rear extension in Cinderford?
The planning route for a kitchen-diner rear extension in Cinderford is set by England's householder rules and your council.
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 Cinderford like to extend?
Stone-built and rendered houses are common around Cinderford, so matching the walling is a design decision in its own right: natural stone, reconstituted stone or a render finish across old and new.
