Kitchen-diner rear extension in Dewsbury
For homes in Dewsbury, 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 Dewsbury (BD19, WF12, WF13 and WF15) as part of our West Yorkshire work. For Dewsbury 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 Dewsbury?
The planning route for a kitchen-diner rear extension in Dewsbury 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.
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 Dewsbury like to extend?
Dewsbury has through terraces and some back-to-backs as well as later semis; back-to-backs have little or no rear space, so we look at side or loft options there.
