Do you need planning permission for a terraced house rear extension in Timperley?
Here is how the rules in England apply to a terraced house rear extension in Timperley.
In England a single-storey rear extension can often be built under permitted development: up to 3 metres beyond the original rear wall of an attached house, or 4 metres on a detached house, no higher than 4 metres, with eaves no higher than 3 metres if any part 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. 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 Timperley like to extend?
Stone and brick terraces are common around Timperley. Where houses back onto a ginnel or alley, deliveries can come in from the rear, which makes the build tidier.

FAQ
Terraced house rear extension questions in Timperley
Will I need a structural engineer?
Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
What postcode areas do you cover around Timperley?
Including M33, WA14 and WA15, and the surrounding Greater Manchester area.
How deep can I go on a terrace?
3 metres under permitted development in England, or up to 6 metres with prior approval outside designated land.
