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

Whether your side return extension in Conisbrough 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 Conisbrough like to extend?

Stone terraces and brick semis are typical of Conisbrough. Matching sandstone or gritstone on a terrace is one of the biggest cost variables, and reclaimed stone is often the best match.

FAQ

Side return extension questions in Conisbrough

Do you handle building control in Conisbrough?

Yes. We apply to the council or a registered building control approver and hand over the completion certificate.

Will I need a structural engineer?

Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.

Glass roof or solid roof with rooflights?

A glass roof gives the most light; a solid roof with long rooflights is warmer and quieter in rain. Both work.

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

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.
