Do you need planning permission for a kitchen-diner rear extension in Stockton-on-Tees?
The planning route for a kitchen-diner rear extension in Stockton-on-Tees is set by England's householder rules and your council.
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.
England also has the larger home extension route: a single-storey rear extension of up to 6 metres on an attached house or 8 metres on a detached house, after prior approval from the council. The council notifies your neighbours and has 42 days to decide; the fee is £249 (£310 for applications made from 8 December 2026). The route is not available on designated land such as conservation areas.
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 Stockton-on-Tees like to extend?
Terraces and semis are typical around Stockton-on-Tees. On terraces a single-storey rear extension across the back yard is usually the practical choice; semis often have room for more.
