Side return extension in Horsforth
For homes in Horsforth, a side return extension is often the simplest way to gain space without moving. Infilling the narrow passage beside a Victorian or Edwardian back addition. We take it from survey to completion certificate.
We cover Horsforth (LS16, LS18 and LS19) as part of our West Yorkshire work. In Horsforth we check the boundary line and the neighbour's gutter before drawing a side return, because a few centimetres decide whether the wall goes on or beside the boundary.

Do you need planning permission for a side return extension in Horsforth?
Planning for a side return extension in Horsforth follows the English householder rules.
In England the side part of a side return or wraparound must meet the side-extension rules (one storey, under 4 metres high, no more than half the width of the original house), and those rights do not apply on designated land. Because a wraparound combines a side and a rear extension, many need householder planning permission.
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 Horsforth like to extend?
Horsforth 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.
