Terraced house rear extension in Bentley
We plan and build rear extensions for terraced houses for homeowners in Bentley. Rear and side return extensions for terraces, with access through the house and two neighbours. Start with a free site visit, then a written price once the design is agreed.
We cover Bentley (DN1, DN2 and DN5) as part of our South Yorkshire work. On a Bentley terrace both neighbours usually need party wall notices or agreement, so we talk to them early.

Do you need planning permission for a terraced house rear extension in Bentley?
The planning route for a terraced house rear extension in Bentley is set by England's householder rules and your council.
English permitted development (Class A) allows a single-storey rear extension of 3 metres on a terraced or semi-detached house and 4 metres on a detached one, measured from the original house, with a maximum height of 4 metres and eaves of no more than 3 metres 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. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Bentley like to extend?
Bentley has through terraces and some back-to-backs as well as later semis; back-to-backs have little or no rear space, so we look at side or loft options there.
