Extensions over a garage across Droitwich Spa
Droitwich Spa homeowners can use us for the whole over-garage extension project: survey, design, planning or permitted development checks, building regulations and the build itself.

Included in a typical project
- Opening into the existing first floor
- Strengthening or rebuilding the garage walls if needed
- Design and householder planning application
- New floor structure, walls and roof
- Structural survey of garage walls and foundations
Fitting the new room to the existing landing is the planning puzzle inside the house. We design the connection first, then the roof, so the extension does not end up with awkward steps or a corridor through a bedroom.
Local to Droitwich Spa
Across WR9, we can visit, measure and advise. Nearby, we also take on projects in Bromsgrove (6 miles), Worcester (6 miles), Stourport-on-Severn (7 miles), Redditch (9 miles).
For homes towards West Midlands, Stourbridge is around 13 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.
Will the council need to approve it?
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.
In a conservation area, national park, National Landscape, the Broads or a World Heritage Site the permitted development limits are tighter (no side or two-storey extensions without an application). Listed homes need listed building consent, and if permitted development rights have been removed, any extension needs an application.
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).

Your questions about an over-garage extension in Droitwich Spa
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Droitwich Spa, 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 Droitwich Spa?
Yes. We cover Droitwich Spa and the surrounding parts of Worcestershire. Site visits are free and there is no obligation.
Will my neighbours in Droitwich Spa be involved?
If a planning application or prior approval is needed, the council notifies neighbours. If the work is on or near a shared boundary, party wall notices may also be needed.
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.
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.
