Side return extensions in Lincolnshire
Infilling the narrow passage beside a Victorian or Edwardian back addition. Rear extensions in Lincolnshire: we cover 17 towns including Lincoln, Grimsby and Scunthorpe, with design, approvals and the build under one contract.
Side returns suit the Victorian and Edwardian terraces found across parts of Lincolnshire, where the kitchen sits in a narrow back addition. Lincolnshire has plenty of inter-war semis and bungalows, and single-storey rear extensions suit both.

Do you need planning permission in Lincolnshire?
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.

FAQ
Questions people ask
How much space does a side return add?
Typically 8 to 18 square metres, enough to turn a galley kitchen into a kitchen-diner with an island.
Do I need my neighbour's permission?
Not their permission, but in England and Wales you must serve party wall notices, and a neighbour can consent in writing or ask for a surveyor's award.
Can I combine a side return with a rear extension?
Yes; that is a wraparound extension, and it gives the biggest open-plan room a terrace can have.
Do you cover all of Lincolnshire?
We cover 17 towns and districts in Lincolnshire, including Lincoln, Grimsby and Scunthorpe.
