Local to Halesowen
Across B32, B62, B63, B64, B65, B68, we can visit, measure and advise. We also work in nearby Brierley Hill (4 miles), Dudley (4 miles), Stourbridge (4 miles), Smethwick (5 miles).
Just over the Worcestershire border, Bromsgrove is about 8 miles away. The West Midlands has a large stock of 1930s and post-war semi-detached houses, which are well suited to rear, side and over-garage extensions, plus Victorian terraces in the older inner areas.
Planning and approvals in Halesowen
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 Halesowen address depends on its history and any designations, which is why we check it at the first visit.
Building regulations approval is separate from planning. In England you can use the council's building control team or a registered building control approver; a full plans application gets the drawings checked before work starts, and the inspector signs the work off with a completion certificate.
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.
Applications are decided by the local planning authority (your district, borough or unitary council).

Questions people ask about wraparound extensions
Do I need building regulations approval in Halesowen?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Halesowen, 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 you cover all of Halesowen?
Yes. We cover Halesowen and the surrounding parts of West Midlands. Site visits are free and there is no obligation.
Do wraparound extensions need planning permission?
Usually, yes. In England the side element counts as a side extension and the rear element as a rear extension, and the combination normally falls outside permitted development. A householder application costs £548 in England from 1 April 2026.
Is a wraparound better than a side return alone?
It adds far more space, but costs more and needs planning permission more often. Our comparison guide sets the two side by side.
