Planning and approvals in Leicestershire

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.

Homes in conservation areas, national parks, National Landscapes (formerly AONBs), the Broads and World Heritage Sites have tighter rules, so we always check the property's status and planning history before design starts.

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.

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).

When an over-garage extension makes sense

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

How the project works

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

    First, a site visit: we look at the house, garden, access and drains and listen to what you need.

  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

    With the design and specification agreed, you get a fixed written price and a start date.

  4. Build and sign-off

    Our team builds the extension, keeps you updated weekly and finishes with building control sign-off.

Questions people ask about over-garage extensions

Can I see a price before committing to anything?

Yes. The guide prices on this page are adjusted for Leicestershire, 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 Leicestershire?

Yes, across the whole of Leicestershire. Site visits are free and there is no obligation.

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

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 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.

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.
