Side return extension in Chester

Side return extension in Chester: infilling the narrow passage beside a Victorian or Edwardian back addition. We measure the house, show you what the rules allow, price it in writing and build it.

Chester is covered from our Cheshire round, including CH1. In Chester 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 Chester?

Whether your side return extension in Chester 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. 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 Chester like to extend?

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

Do I need planning permission for a rear extension in Chester?

Often not for a single-storey rear extension of up to 3 metres (4 metres on a detached house) under permitted development, or up to 6 or 8 metres with prior approval, unless the house is in a conservation area or its rights have been removed.

How long does a rear extension take to build in Chester?

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 Chester house?

We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
