Do you need planning permission for a side return extension in Newcastle upon Tyne?
Here is how the rules in England apply to a side return extension in Newcastle upon Tyne.
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 Newcastle upon Tyne like to extend?
Brick terraces, colliery houses and post-war semis make up much of Newcastle upon Tyne. Former mining areas often need a coal mining risk check before foundations are designed.
