Terraced house rear extension in Denton
Rear and side return extensions for terraces, with access through the house and two neighbours. We design, get the approvals for and build rear extensions for terraced houses in Denton and the surrounding area, with one contract from the first survey to building control sign-off.
We cover Denton (M34, M43 and SK16) as part of our Greater Manchester work. Terraced streets make up much of the housing in parts of Greater Manchester, and most rear extensions here go in without side access.

Do you need planning permission for a terraced house rear extension in Denton?
Here is how the rules in England apply to a terraced house rear extension in Denton.
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. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.
What are homes in Denton like to extend?
Stone and brick terraces are common around Denton. Where houses back onto a ginnel or alley, deliveries can come in from the rear, which makes the build tidier.

Yes. We visit, measure up and talk through the options with no cost and no obligation.
Do both neighbours need party wall notices?
Usually yes in England and Wales, because the extension often sits on or near both boundaries.

Including M34, M43 and SK16, and the surrounding Greater Manchester area.
How long does a rear extension take to build in Denton?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Can you match the brick or stone on my Denton house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
