Pitched and lean-to roof rear extensions in Surrey
Lean-to, gable and hipped roofs that give a vaulted ceiling. We design and build rear extensions across Surrey, from Woking and Guildford to Esher, covering single-storey kitchen extensions, two-storey additions, side returns and wraparounds.
Pitched roofs suit the cottages and slate-roofed houses in parts of Surrey. Around Surrey the housing ranges from inter-war semis to 1960s and 1970s estates with good-sized gardens. Many of the newer estates had permitted development rights removed by condition, so we check the planning history before anything is drawn.
How much does a pitched-roof rear extension cost in Surrey?
For Surrey we work from the South East England rate: £2,240–£3,640 per square metre of new floor, including VAT, standard specification. 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) | £27,000–£43,500 |
| 4 m wide × 5 m deep (20 m²) | £45,000–£73,000 |
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?
In England a single-storey rear extension can often be built under permitted development: up to 3 metres beyond the original rear wall of an attached house, or 4 metres on a detached house, no higher than 4 metres, with eaves no higher than 3 metres if any part is within 2 metres of a boundary.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent.

FAQ
Questions people ask
Will a lean-to fit under my windows?
We check the sill heights at the survey; low windows usually mean a flat roof instead.
Are roof windows allowed?
Yes; they are the usual way to bring light into a pitched-roof extension.
Is a pitched roof more expensive?
Slightly, typically a few per cent more than a flat roof of the same area.
