Kitchen-diner rear extension in Cricklewood
For homes in Cricklewood, a kitchen-diner rear extension is often the simplest way to gain space without moving. An open-plan kitchen, dining and family room that opens straight onto the garden. We take it from survey to completion certificate.
We cover Cricklewood (NW2, NW6 and NW11) as part of our Greater London work. For Cricklewood kitchens we plan the extraction route and the island drainage before the slab is poured, so nothing has to be chased in later.

Do you need planning permission for a kitchen-diner rear extension in Cricklewood?
The planning route for a kitchen-diner rear extension in Cricklewood is set by England's householder rules and your council.
In England a single-storey rear extension can often be built under permitted development: up to 3 metres beyond the original rear wall of an attached house, or 4 metres on a detached house, no higher than 4 metres, with eaves no higher than 3 metres if any part is 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. At the first visit we measure what is there now and tell you which route fits: permitted development, prior approval or a planning application.
What are homes in Cricklewood like to extend?
Period terraces in Cricklewood sit alongside flats, and the difference matters: houses usually keep permitted development rights, while flats and maisonettes need planning permission for any rear extension.
