Rear extensions for bungalows in Berkshire
Single-storey rear extensions that keep everything on one level. Rear extensions in Berkshire: we cover 14 towns including Reading, Slough and Bracknell, with design, approvals and the build under one contract.
For bungalows in Berkshire, a rear extension is the usual way to add space without adding stairs. Commuter semis and detached houses make up much of Berkshire, and longer gardens make England's prior approval route for deeper rear extensions worth considering.
How much does a bungalow rear extension cost in Berkshire?
A bungalow rear extension in Berkshire is priced at £2,070–£3,360 per square metre including VAT as a guide, before kitchen fit-out and fees. South East prices run above our West Midlands baseline, mainly on labour rates and clay-soil foundations.

| 4 m wide × 6 m deep (24 m²) | £49,500–£80,500 |
These are guide ranges; the written quote after the survey is the figure that counts.
Do you need planning permission in Berkshire?
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.
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 Berkshire?
We cover 14 towns and districts in Berkshire, including Reading, Slough and Bracknell.
