Do you need planning permission for a kitchen-diner rear extension in Tiverton?
Whether your kitchen-diner rear extension in Tiverton needs a planning application depends on its size, your house and any local restrictions.
English permitted development (Class A) allows a single-storey rear extension of 3 metres on a terraced or semi-detached house and 4 metres on a detached one, measured from the original house, with a maximum height of 4 metres and eaves of no more than 3 metres within 2 metres of a boundary.
If 3 or 4 metres is not enough, England's prior approval route allows 6 metres on a terraced or semi-detached house and 8 metres on a detached house for a single-storey rear extension. Neighbours are consulted, the council decides within 42 days, and the fee is £249, rising to £310 from 8 December 2026.
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 Tiverton like to extend?
Stone-built and rendered houses are common around Tiverton, so matching the walling is a design decision in its own right: natural stone, reconstituted stone or a render finish across old and new. For Tiverton kitchens we plan the extraction route and the island drainage before the slab is poured, so nothing has to be chased in later.
