Single-storey rear extension in Cudworth

Single-storey rear extension in Cudworth: ground-floor space across the back of the house, usually for a kitchen, dining or family room. We measure the house, show you what the rules allow, price it in writing and build it.

We cover Cudworth (S70, S71 and S72) as part of our South Yorkshire work. On stone terraces and brick semis like those around Cudworth, a single-storey rear extension is usually the simplest way to fix a small back kitchen without touching the bedrooms.

Your written price follows a measured survey and an agreed design, so it reflects your house, not an average.

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

The planning route for a single-storey rear extension in Cudworth is set by England's householder rules and your council.

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. 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 Cudworth like to extend?

Stone terraces and brick semis are typical of Cudworth. Matching sandstone or gritstone on a terrace is one of the biggest cost variables, and reclaimed stone is often the best match.

FAQ

Single-storey rear extension questions in Cudworth

Do you handle building control in Cudworth?

Yes. We apply to the council or a registered building control approver and hand over the completion certificate.

What postcode areas do you cover around Cudworth?

Including S70, S71 and S72, and the surrounding South Yorkshire area.

How deep can a single-storey rear extension be without planning?

In England, 3 metres on an attached house and 4 metres on a detached house under permitted development, or up to 6 and 8 metres with prior approval. Wales allows 4 metres; Scotland and Northern Ireland have their own limits.

Who will build my extension?

Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.

Can I live at home while the extension is built?

Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.

Can you match the brick or stone on my Cudworth house?

We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
