Kitchen-diner rear extension in Whittlesey
We plan and build kitchen-diner rear extensions for homeowners in Whittlesey. An open-plan kitchen, dining and family room that opens straight onto the garden. Start with a free site visit, then a written price once the design is agreed.
We cover Whittlesey (PE7) as part of our Cambridgeshire work. A kitchen-diner is often the reason people in Whittlesey extend: the back kitchen in Victorian terraces and 1930s semis is rarely big enough for a table.

Do you need planning permission for a kitchen-diner rear extension in Whittlesey?
Planning for a kitchen-diner rear extension in Whittlesey follows the English householder rules.
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 Whittlesey like to extend?
Whittlesey mixes Victorian terraces with 1930s semis, so both side returns and full-width kitchen extensions suit houses here.
