Converting a garage is a popular way to add a room without extending. Structurally, two things usually happen: the big garage door opening is filled in with a wall, window or door on proper foundations, and a doorway or wider opening is formed through the wall between the garage and the house.

Worth knowing before you start

  • The infill wall facing the street is the part everyone sees. Bricks and mortar are matched to the house as closely as possible, or the panel is rendered or clad, and the new window is aligned with the others on the front elevation.
  • Garages often hold gas meters, consumer units, boilers or water stopcocks. These are located at survey, and anything that needs moving is done by the right trade, including a Gas Safe registered engineer for any work on gas pipework.
  • An integral garage is usually separated from the house by fire-resisting construction. If part of it stays as a garage or store, that separation must be kept, and any new door between garage and house normally needs to be a fire door.
  • The price depends on whether the garage door beam needs replacing, the foundation needed for the infill, whether a new opening is formed into the house, the brick or cladding finish, and any fire separation work that has to be kept or added.
  • Forming a doorway from the house into the converted garage often goes through a load-bearing wall, especially the original external wall of the house where the garage is attached. That opening needs a lintel or beam designed by the engineer.

From survey to sign-off in Wigan

  1. Free visit

    A short visit to Wigan to see the job, agree what you want and check the bearings, floors and services that affect the design.

  2. Calculations

    The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.

  3. Building control

    We submit a building notice or full plans application to Wigan Council, so approval is in place before the wall is touched.

  4. Steel in, made good

    On site we prop, open up, fit and pack the steel, then fire protect, box in and plaster once the inspection is done.

Building control and neighbours in Wigan

For Wigan, building control is provided by Wigan Council, or by a registered building control approver if preferred. We send them the engineer's calculations with a building notice or full plans application and book the inspections. Work done without approval can cause problems at sale and is far dearer to put right later.

If the beam bears into a wall you share with a neighbour, the Party Wall etc. Act 1996 applies, and a party structure notice must be served at least two months before that work starts. We arrange this through a party wall surveyor.

Garage conversion openings in Wigan: your questions

Do you cover Wigan for garage conversion openings?

Yes. We carry out garage conversion openings in Wigan and the WN1, WN2, WN3, WN5 and WN6 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.

Can you work on older or listed homes in Wigan?

Yes. Older homes often have lime mortar, timber lintels or shallow footings, which the engineer allows for. Listed buildings need listed building consent for internal structural changes as well as building regulations approval, and that must be in place first.

What paperwork will I get when the conversion is done?

You should receive the engineer's calculations, a building control completion certificate for the conversion, and certificates for any electrical or gas work. Keep these together, as buyers' solicitors ask for evidence that a garage conversion was approved, especially where a garage has become a bedroom or living space.

Do I need planning permission to convert my garage?

Often not, because a garage conversion is largely internal work within permitted development. However, some newer estates have planning conditions that remove permitted development rights for garages, and listed buildings, flats and some front elevation changes need consent. Check your property's planning history with the council before committing.

Can I convert an integral garage with a bedroom above?

Yes, and it is a common type of conversion. The main structural point is the beam over the garage door, which usually carries the front wall of the bedroom. The engineer checks its condition and capacity, and the floor between garage and bedroom may need fire protection and insulation upgrades as part of the work.
