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.

Things to plan for

  • Garages built before 2000 can contain asbestos cement in roof sheets, wall panels or the garage door itself. A survey of the materials being disturbed is needed before work starts, so any asbestos can be removed or managed correctly.
  • A converted garage used as a bedroom needs a suitable means of escape, often an escape window, and every habitable room needs ventilation. These affect the size and type of window in the infill wall, so they are agreed before brickwork starts.
  • 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.
  • An infill wall needs a proper foundation. Garage floors are often a thin slab with no footing under the door line, so a new trench footing is usually dug across the opening to a depth and width the engineer and building control agree.

How the job runs in Castleford

  1. Survey in Castleford

    We visit, look at the wall and what sits above it, measure the opening and note services, access and how the steel can be brought in.

  2. Engineer's design

    A structural engineer sizes the beam, padstones and any posts, and sets out the temporary support needed while the wall is out.

  3. Building control

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

  4. Install and sign-off

    Props go in, the opening is formed, the steel is set and packed, building control inspects it, and we make good.

Approvals in Castleford

In England, taking out a load-bearing wall or putting in a beam is building work under the Building Regulations 2010. It needs approval from building control, either Wakefield Council or a registered building control approver, through a full plans application or a building notice. Part A covers the structure and Part B covers fire safety, which is why steel in homes is usually fire protected.

Terraced and semi-detached homes often need party wall notices, because cutting into a shared wall to take a beam end is notifiable under the Party Wall etc. Act 1996. Allow at least two months for the notice period unless your neighbour agrees sooner.

Local questions answered

Do you also work near Castleford?

Yes. We also cover nearby towns including Pontefract, Wakefield, Leeds and Ossett.

Can you work on older or listed homes in Castleford?

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.

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 knock through from my garage into the kitchen?

Usually, yes. The wall between an attached or integral garage and the house is often load-bearing, so the opening needs a lintel or steel beam designed by a structural engineer and approved by building control. If any of the garage stays as storage, the opening needs fire separation, such as a fire door.

Is my garage floor suitable for a living room?

Rarely as it stands. Garage floors are often lower than the house, may slope towards the door and usually lack insulation and a damp-proof membrane. The floor is normally built up with a membrane, insulation and screed or a timber floor to meet the house level and the building regulations.
