Covering Beverley

Across HU17, we can visit, measure and advise. We also work in nearby Hull (8 miles), Brough (10 miles), Bridlington (19 miles), Goole (21 miles).

Just over the Lincolnshire border, Scunthorpe is about 21 miles away. Homes across Yorkshire and the Humber range from back-to-back and through terraces to large suburban semis, and extension options vary with them.

Included in a typical project

  • Opening into the existing first floor
  • Insulation, electrics, heating and finish
  • Structural survey of garage walls and foundations
  • Design and householder planning application
  • Strengthening or rebuilding the garage walls if needed

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 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.

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).

Over-garage extension questions answered

How long does an over-garage extension take to build in Beverley?

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 Beverley?

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.

Will my neighbours in Beverley 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.

Does building over a garage need planning permission?

In England and the rest of the UK, adding a storey over a side garage almost always needs a planning application, because two-storey side extensions are outside permitted development.

How much does a room over a garage cost?

Our guide range is about £1,690 to £3,200 per m² including VAT. A single-garage room of about 12 m² usually costs £23,500 to £30,500 at standard spec, more if the garage needs rebuilding.
