Covering Bebington
Our survey diary covers Bebington, including CH41, CH42, CH43, CH62, CH63. The same team covers Birkenhead (3 miles), Heswall (4 miles), Liverpool (4 miles), Wallasey (5 miles), all within easy reach.
Across the North West, terraced houses with small rear yards suit compact rear and side return extensions, while suburban semis have room for more.
Included in a typical project
- New floor structure, walls and roof
- Structural survey of garage walls and foundations
- Strengthening or rebuilding the garage walls if needed
- Insulation, electrics, heating and finish
- Opening into the existing first floor
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.
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.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
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.
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).

Over-garage extension questions answered
Do I need building regulations approval in Bebington?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Do you cover all of Bebington?
Yes. We cover Bebington and the surrounding parts of Merseyside. Site visits are free and there is no obligation.
How long does an over-garage extension take to build in Bebington?
On site, typically 12 to 18 weeks once approvals are in place. Before that, allow 8–14 weeks design and approvals.
How much does a room over a garage cost?
Our guide range is about £1,710 to £3,230 per m² including VAT. A single-garage room of about 12 m² usually costs £23,500 to £31,000 at standard spec, more if the garage needs rebuilding.
Can I keep using the garage during the build?
Usually not for parking. The garage roof is removed and the space below is used for access and props for part of the build.
