For bungalows in Bristol and South Gloucestershire, a rear extension is the usual way to add space without adding stairs. Stone-built and rendered houses are common around Bristol and South Gloucestershire, so matching the walling is a design decision in its own right: natural stone, reconstituted stone or a render finish across old and new.

How much does a bungalow rear extension cost in Bristol and South Gloucestershire?

For Bristol and South Gloucestershire we work from the South West England rate: £1,920–£3,120 per square metre of new floor, including VAT, standard specification. South West prices run slightly above our West Midlands baseline; natural stone to match the house is the main variable.

Do you need planning permission in Bristol and South Gloucestershire?

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 Bristol and South Gloucestershire?

We cover 6 towns and districts in Bristol and South Gloucestershire, including Bristol, Kingswood and Mangotsfield.

Who builds the extension?

Vetted building teams working under contract to us; your contract is with S&K Property Investments and Improvement Ltd.
