Side return extension in Altrincham

For homes in Altrincham, 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.

Altrincham is covered from our Greater Manchester round, including M33, WA14 and WA15. Side returns suit the Victorian and Edwardian terraces found across parts of Greater Manchester, where the kitchen sits in a narrow back addition.

Do you need planning permission for a side return extension in Altrincham?

Whether your side return extension in Altrincham needs a planning application depends on its size, your house and any local restrictions.

Side return infills and the side leg of a wraparound are treated as side extensions in England: single-storey, no more than 4 metres high and no wider than half the original house. They are not permitted development in conservation areas, National Parks or National Landscapes, and a joined wraparound often needs a planning application because the side and rear rules apply together.

The Party Wall etc. Act 1996 applies in England: you serve notice two months before work to a shared wall, and one month before digging foundations within 3 metres (or 6 metres for deeper foundations) of a neighbour's building. Neighbours can agree in writing; if they dissent, surveyors agree an award.

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 Altrincham like to extend?

Stone and brick terraces are common around Altrincham. Where houses back onto a ginnel or alley, deliveries can come in from the rear, which makes the build tidier.
