Local to Camberley

Our survey diary covers Camberley, including GU15, GU16. The same team covers Woking (8 miles), Farnham (9 miles), Guildford (10 miles), Egham (10 miles), all within easy reach.

The South East has a broad mix of 1930s semis, post-war estates, newer developments and period cottages, and many houses have enough garden for a generous rear extension.

Planning rules that apply in Camberley

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.

Applications are decided by the local planning authority (your district, borough or unitary council).

When an over-garage extension makes sense

  • Families needing a bedroom without losing garden
  • Homes where the landing can connect to the new room
  • Detached and link-detached houses with an attached garage

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.

What happens next

Site visits are free and there is no obligation. Where drawings are needed, the design stage is priced in writing before it starts.

  1. Free site visit

    It starts with a visit to your house to measure, check access and talk through ideas and budget.

  2. Design and approvals

    We draw the design, agree it with you and handle planning or permitted development checks and building regulations.

  3. Fixed written price

    The price is fixed in writing once the design is settled, with a clear programme and payment stages.

  4. Build and sign-off

    Work is carried out to the agreed programme, inspected by building control and signed off at the end.

Common questions in Camberley

Who do I contract with for an over-garage extension in Camberley?

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.

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

On site, typically 12 to 18 weeks once approvals are in place. Before that, allow 8–14 weeks design and approvals.

Can I see a price before committing to anything?

Yes. The guide prices on this page are adjusted for Camberley, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.

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 £2,020 to £3,810 per m² including VAT. A single-garage room of about 12 m² usually costs £28,000 to £36,500 at standard spec, more if the garage needs rebuilding.
