Rear extensions for bungalows in South Yorkshire
Single-storey rear extensions that keep everything on one level. Rear extensions in South Yorkshire: we cover 27 towns including Sheffield, Rotherham and Doncaster, with design, approvals and the build under one contract.
For Sheffield bungalows we design the roof first, because the low eaves decide the height of the new room. Stone terraces and brick semis are typical of South Yorkshire. Matching sandstone or gritstone on a terrace is one of the biggest cost variables, and reclaimed stone is often the best match.
How much does a bungalow rear extension cost in South Yorkshire?
In South Yorkshire, our guide for a bungalow rear extension is £1,720–£2,790 per square metre including VAT for a standard specification. Yorkshire prices sit below our West Midlands baseline; matching natural stone is the main variable.
| Size | Guide price inc VAT |
|---|---|
| 3 m wide × 4 m deep (12 m²) | £20,500–£33,500 |
| 4 m wide × 6 m deep (24 m²) | £41,500–£67,000 |
Your written price follows a measured survey and an agreed design, so it reflects your house, not an average.
Do you need planning permission in South Yorkshire?
English permitted development (Class A) allows a single-storey rear extension of 3 metres on a terraced or semi-detached house and 4 metres on a detached one, measured from the original house, with a maximum height of 4 metres and eaves of no more than 3 metres 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.

FAQ
Questions people ask
Can a bungalow extension be fully accessible?
Yes: level thresholds, wider doors and a wet room are straightforward to design in.
Will the roof look odd?
Not if the pitch and tiles match. Where the eaves are low, a flat-roofed section with a lantern is an alternative.
Can I extend the loft as well?
Sometimes, but that is a different project; a rear extension keeps everything on one level.
Do you cover all of South Yorkshire?
We cover 27 towns and districts in South Yorkshire, including Sheffield, Rotherham and Doncaster.
Who builds the extension?
Vetted building teams working under contract to us; your contract is with S&K Property Investments and Improvement Ltd.
