Local to Brierley Hill
Postcode districts we cover around Brierley Hill include B64, DY2, DY5, DY6, DY8. We also work in nearby Stourbridge (2 miles), Dudley (2 miles), Kingswinford (2 miles), Halesowen (4 miles).
For homes towards Worcestershire, Kidderminster is around 8 miles away. Across the West Midlands, brick-built semis with long gardens are common, so single-storey and two-storey rear extensions are popular choices.
Planning rules that apply in Brierley Hill
In England any side extension over one storey, including a room built over a side garage, needs a householder planning application. The fee is £548 from 1 April 2026 and councils aim to decide within 8 weeks.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
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).
What we take care of
- New floor structure, walls and roof
- Strengthening or rebuilding the garage walls if needed
- Design and householder planning application
- Structural survey of garage walls and foundations
- Insulation, electrics, heating and finish

Over-garage extension questions answered
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Brierley Hill, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
How long does an over-garage extension take to build in Brierley Hill?
On site, typically 12 to 18 weeks once approvals are in place. Before that, allow 8–14 weeks design and approvals.
Who do I contract with for an over-garage extension in Brierley Hill?
Your contract is with S&K Property Investments and Improvement Ltd, which designs and manages the project and the build teams who carry it out.
Can my garage take the weight of a room on top?
Some can and some cannot. Many garages have a single-skin wall or shallow foundations. Our structural engineer checks this before we give a fixed price.
How much does a room over a garage cost?
Our guide range is about £1,750 to £3,300 per m² including VAT. A single-garage room of about 12 m² usually costs £24,000 to £31,500 at standard spec, more if the garage needs rebuilding.
