Do I need planning permission in Redcar?

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.

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).

What we take care of

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

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.

Our process, step by step

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

    We visit your Redcar home, measure up, talk through what you want and check the planning position.

  2. Design and approvals

    Once the layout is agreed, we deal with the council: planning permission or written confirmation that none is needed, plus building control.

  3. Fixed written price

    We confirm the build price in writing, based on the approved drawings and the finishes you have chosen.

  4. Build and sign-off

    We build it with one project manager, book the building control inspections and hand over the completion certificate.

Questions people ask about over-garage extensions

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

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

Do you cover all of Redcar?

Yes. We cover Redcar and the surrounding parts of North Yorkshire. Site visits are free and there is no obligation.

Do I need building regulations approval in Redcar?

Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.

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.
