Wraparound extension in Southall
An L-shaped extension that fills the side return and runs across the back. We design, get the approvals for and build wraparound extensions in Southall and the surrounding area, with one contract from the first survey to building control sign-off.
We cover Southall (UB1, UB2, UB5 and UB6) as part of our Greater London work. In Southall we usually draw the wraparound and a simpler rear-only option side by side, so the planning risk and cost difference are clear.

Do you need planning permission for a wraparound extension in Southall?
Here is how the rules in England apply to a wraparound extension in Southall.
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. 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 Southall like to extend?
Southall is mostly 1930s semis, short terraces and post-war houses, so full-width single-storey and two-storey rear extensions are realistic on many plots. Some later estates had permitted development rights removed by condition, so we check the planning history first.

Wraparound extension questions in Southall
Do you handle building control in Southall?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
Can you match the brick or stone on my Southall house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
What roof suits a wraparound?
A flat roof with a lantern, a standing-seam pitched roof or a glazed roof over the side leg. The choice usually follows the first-floor windows above.
