Pitched and lean-to roof rear extensions in Bristol and South Gloucestershire
Lean-to, gable and hipped roofs that give a vaulted ceiling. We design and build rear extensions across Bristol and South Gloucestershire, from Bristol and Kingswood to Mangotsfield, covering single-storey kitchen extensions, two-storey additions, side returns and wraparounds.
Pitched roofs suit the cottages and slate-roofed houses in parts of Bristol and South Gloucestershire. 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 pitched-roof rear extension cost in Bristol and South Gloucestershire?
Guide prices for a pitched-roof rear extension in Bristol and South Gloucestershire start from our South West England rate of £2,080–£3,380 per square metre, including VAT. South West prices run slightly above our West Midlands baseline; natural stone to match the house is the main variable.

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 Bristol and South Gloucestershire?
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.
