Kitchen-diner rear extension in Rugby
Kitchen-diner rear extension in Rugby: an open-plan kitchen, dining and family room that opens straight onto the garden. We measure the house, show you what the rules allow, price it in writing and build it.
Rugby sits in Warwickshire, with postcode districts including CV21 and CV22. We usually keep the working kitchen where the old one was and put the dining table in the new space by the doors, which suits most Rugby homes.

Do you need planning permission for a kitchen-diner rear extension in Rugby?
Whether your kitchen-diner rear extension in Rugby needs a planning application depends on its size, your house and any local restrictions.
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. 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 Rugby like to extend?
Rugby has a lot of post-war semis and estate houses with long gardens and side access, which makes rear extensions quicker to build.
