Planning and approvals in Walsall
In England a wraparound extension is assessed as both a side and a rear extension, and the combination usually falls outside permitted development, so most need a householder planning application (£548 from 1 April 2026).
The planning position for a specific Walsall address depends on its history and any designations, which is why we check it at the first visit.
If the work involves a shared wall, building on the boundary, or digging foundations within 3 m (sometimes 6 m) of a neighbour's building, the Party Wall etc. Act 1996 applies and notice must be served before work starts: two months for work to a party wall, one month for new walls on the boundary and for excavations.
Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.
Applications are decided by the local planning authority (your district, borough or unitary council).

Working in Walsall
Our survey diary covers Walsall, including WS1, WS2, WS3, WS4, WS5, WS10. Nearby, we also take on projects in Bloxwich (2 miles), Wednesbury (3 miles), Aldridge (3 miles), Willenhall (3 miles).
Across the West Midlands, brick-built semis with long gardens are common, so single-storey and two-storey rear extensions are popular choices.
What is included
- Foundations, drainage and any manhole relocation
- Survey, design and 3D layout options
- Householder planning application
- Full internal finish or kitchen-ready shell
- Party wall notice support (England and Wales)
- Roof with glazing along the side return
The corner is where wraparounds succeed or fail. We usually use a single steel goalpost or a corner post hidden in a pier, and set the glazing so the new room reads as one space rather than two boxes.

Questions people ask about wraparound extensions
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Walsall, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Do I need building regulations approval in Walsall?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
How long does a wraparound extension take to build in Walsall?
On site, typically 14 to 20 weeks once approvals are in place. Before that, allow 8–16 weeks design and approvals.
Will I need to move a drain?
Often. Side returns frequently contain a manhole or a shared drain. Building near or over a public sewer needs the water company’s consent in England and Wales, which we arrange.
How much does a wraparound extension cost?
Our guide range is about £1,940 to £3,590 per m² including VAT. A 25 m² standard-spec wraparound typically lands around £55,500 to £70,500 in Walsall before design and council fees.
