Single-storey rear extension in Coventry

For homes in Coventry, a single-storey rear extension is often the simplest way to gain space without moving. Ground-floor space across the back of the house, usually for a kitchen, dining or family room. We take it from survey to completion certificate.

Coventry sits in the West Midlands, with postcode districts including CV2, CV3, CV4 and CV5. On red-brick terraces and 1930s semis like those around Coventry, a single-storey rear extension is usually the simplest way to fix a small back kitchen without touching the bedrooms.

Do you need planning permission for a single-storey rear extension in Coventry?

Whether your single-storey rear extension in Coventry 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.

If 3 or 4 metres is not enough, England's prior approval route allows 6 metres on a terraced or semi-detached house and 8 metres on a detached house for a single-storey rear extension. Neighbours are consulted, the council decides within 42 days, and the fee is £249, rising to £310 from 8 December 2026.

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 Coventry like to extend?

Red-brick terraces and 1930s semis make up much of Coventry. Many already have a small kitchen lean-to at the back, which a new rear extension usually replaces rather than adds to.

    We visit free of charge, measure up, check access, drainage and neighbours' extensions, and note what you want the room to do.
