For homes in Brownhills, 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 Brownhills (WS8) as part of our West Midlands work. For Brownhills 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 Brownhills?
Planning for a kitchen-diner rear extension in Brownhills follows the English householder rules.
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. 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 Brownhills like to extend?
Brownhills has a lot of post-war semis and estate houses with long gardens and side access, which makes rear extensions quicker to build.

Kitchen-diner rear extension questions in Brownhills

What postcode areas do you cover around Brownhills?
Including WS8, and the surrounding West Midlands area.
Can I add a utility room?
Often. A narrow utility or boot room along one side keeps the washing machine out of the open-plan space.

We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
