Bristol and South Gloucestershire
Knocking through to a rear extension in Bristol and South Gloucestershire
Steel beams, padstones and props to open the back of the house safely. 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.
Older houses in Bristol and South Gloucestershire often have solid brick back walls carrying a lot of weight, so the steel design comes early. Bristol and South Gloucestershire has Victorian terraces nearer the centre and post-war semis on the edges. Sloping gardens are frequent, which affects floor levels and steps down to the patio.
What does it cost in Bristol and South Gloucestershire?
As a guide, £3,500–£9,000 including VAT. Ground conditions, glazing, the roof and how far the house is opened up move the final figure within the range.
What approvals does it need in Bristol and South Gloucestershire?
Planning and Building Regulations are separate in England: even a permitted development extension is inspected for foundations, drainage, structure, insulation, fire safety and ventilation, through the council or a registered building control approver, ending with a completion certificate.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent.
