Pitched and lean-to roof rear extensions in Derbyshire
Lean-to, gable and hipped roofs that give a vaulted ceiling. We design and build rear extensions across Derbyshire, from Derby and Chesterfield to High Peak, covering single-storey kitchen extensions, two-storey additions, side returns and wraparounds.
Pitched roofs suit the cottages and slate-roofed houses in parts of Derbyshire. Derbyshire has plenty of inter-war semis and bungalows, and single-storey rear extensions suit both.
How much does a pitched-roof rear extension cost in Derbyshire?
Guide prices for a pitched-roof rear extension in Derbyshire start from our East Midlands rate of £1,940–£3,150 per square metre, including VAT. East Midlands prices sit a little below our West Midlands baseline.

| 4 m wide × 5 m deep (20 m²) | £39,000–£63,000 |
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 Derbyshire?
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.
Do you cover all of Derbyshire?
We cover 22 towns and districts in Derbyshire, including Derby, Chesterfield and High Peak.
