Do you need planning permission for a side return extension in St Ives?
The planning route for a side return extension in St Ives is set by England's householder rules and your council.
In England the side part of a side return or wraparound must meet the side-extension rules (one storey, under 4 metres high, no more than half the width of the original house), and those rights do not apply on designated land. Because a wraparound combines a side and a rear extension, many need householder planning permission.
Because rear extensions often sit on or near the boundary, the Party Wall etc. Act 1996 usually applies in England. Notices go out one or two months before work depending on the type of work, and a surveyor's award is only needed if a neighbour does not consent.
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 St Ives like to extend?
St Ives mixes Victorian terraces with 1930s semis, so both side returns and full-width kitchen extensions suit houses here.

FAQ
Side return extension questions in St Ives
What postcode areas do you cover around St Ives?
Including PE27, and the surrounding Cambridgeshire area.
Do I need planning permission for a rear extension in St Ives?
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.
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.
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.
Do you handle building control in St Ives?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
Can you match the brick or stone on my St Ives house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
