Do you need planning permission for a terraced house rear extension in West Ham?
The planning route for a terraced house rear extension in West Ham 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. At the first visit we measure what is there now and tell you which route fits: permitted development, prior approval or a planning application.
What are homes in West Ham like to extend?
Period terraces in West Ham sit alongside flats, and the difference matters: houses usually keep permitted development rights, while flats and maisonettes need planning permission for any rear extension.

Including E7, E13 and E15, and the surrounding Greater London area.
Can you match the brick or stone on my West Ham house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.

Many Victorian terraces are. Your council's map shows it; we check at the survey.

Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
