Rear extensions for terraced houses in Bristol and South Gloucestershire
Rear and side return extensions for terraces, with access through the house and two neighbours. Across Bristol and South Gloucestershire we handle the whole rear extension: survey, drawings, the planning route, building control and the build. Towns we cover here include Bristol, Kingswood and Mangotsfield.
Terraced streets make up much of the housing in parts of Bristol and South Gloucestershire, and most rear extensions here go in without side access. 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.

Do you need planning permission in Bristol and South Gloucestershire?
Under England's householder permitted development rules you can usually add 3 metres at the back of an attached house, or 4 metres on a detached house, without a planning application, as long as the extension stays under 4 metres high and its eaves stay under 3 metres where it is within 2 metres of a boundary.
Because rear extensions often sit on or near the boundary, the Party Wall etc. Act 1996 usually applies in England. Notices go out one or two months before work depending on the type of work, and a surveyor's award is only needed if a neighbour does not consent.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent.
