Wraparound extension in West Bromwich
For homes in West Bromwich, a wraparound extension is often the simplest way to gain space without moving. An L-shaped extension that fills the side return and runs across the back. We take it from survey to completion certificate.
West Bromwich and its postcode districts B66, B67, B69 and B70 are part of our West Midlands coverage. Wraparounds are the natural next step for the end-of-terrace and Victorian houses in the West Midlands where a side return alone would leave the room too narrow.

Do you need planning permission for a wraparound extension in West Bromwich?
The planning route for a wraparound extension in West Bromwich is set by England's householder rules and your council.
Side return infills and the side leg of a wraparound are treated as side extensions in England: single-storey, no more than 4 metres high and no wider than half the original house. They are not permitted development in conservation areas, National Parks or National Landscapes, and a joined wraparound often needs a planning application because the side and rear rules apply together.
The Party Wall etc. Act 1996 applies in England: you serve notice two months before work to a shared wall, and one month before digging foundations within 3 metres (or 6 metres for deeper foundations) of a neighbour's building. Neighbours can agree in writing; if they dissent, surveyors agree an award.
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 West Bromwich like to extend?
West Bromwich has a lot of post-war semis and estate houses with long gardens and side access, which makes rear extensions quicker to build.

FAQ
Wraparound extension questions in West Bromwich
How long does a rear extension take to build in West Bromwich?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Do I need a party wall agreement?
In England, usually yes if the extension is on or near a shared boundary or the foundations are close to a neighbour's building. We serve the notices.
Is it worth it over a side return alone?
If you want a dining table and a sofa as well as the kitchen, usually yes.
Will I need a structural engineer?
Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
