Wraparound extension in Streetly
We plan and build wraparound extensions for homeowners in Streetly. An L-shaped extension that fills the side return and runs across the back. Start with a free site visit, then a written price once the design is agreed.
Streetly and its postcode districts B44, B73 and B74 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 Streetly?
Planning for a wraparound extension in Streetly follows the English householder rules.
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 Streetly like to extend?
Streetly has a lot of post-war semis and estate houses with long gardens and side access, which makes rear extensions quicker to build.
