Rear extensions for bungalows in Surrey
Single-storey rear extensions that keep everything on one level. Across Surrey we handle the whole rear extension: survey, drawings, the planning route, building control and the build. Towns we cover here include Woking, Guildford and Esher.

For bungalows in Surrey, a rear extension is the usual way to add space without adding stairs. Commuter semis and detached houses make up much of Surrey, and longer gardens make England's prior approval route for deeper rear extensions worth considering.
How much does a bungalow rear extension cost in Surrey?
Guide prices for a bungalow rear extension in Surrey start from our South East England rate of £2,070–£3,360 per square metre, including VAT. South East prices run above our West Midlands baseline, mainly on labour rates and clay-soil foundations.
| Size | Guide price inc VAT |
|---|---|
| 3 m wide × 4 m deep (12 m²) | £25,000–£40,500 |
| 4 m wide × 6 m deep (24 m²) | £49,500–£80,500 |
We put a fixed price in writing once the design is agreed, and explain any provisional sums such as foundations.
Do you need planning permission in Surrey?
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.

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 Surrey?
We cover 35 towns and districts in Surrey, including Woking, Guildford and Esher.
Who builds the extension?
