Garage conversion openings in Broxburn: how it works

We carry out garage conversion openings in Broxburn, covering the EH52 and EH53 postcode districts. We also cover the surrounding towns and villages in West Lothian. The job starts with a free survey visit so the engineer's calculations are based on your actual walls, floors and loads.

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.

What to expect

  • 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.
  • 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 standards agree.
  • The structural part of a garage conversion, covering the infill foundation, the wall and any new opening, typically takes one to two weeks. The full conversion with insulation, electrics, plastering and flooring takes longer, depending on the scope.
  • 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.
  • 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.

What happens, step by step

  1. Free visit

    A short visit to Broxburn 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 warrant

    A building warrant is applied for from West Lothian Council, and work starts only once the warrant has been granted.

  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 rules for Broxburn

Steel beam work in Broxburn needs a building warrant from West Lothian Council. The structural design is part of the application, and the council's building standards team accepts the completion certificate once the work is done as approved.

Scotland has no Party Wall Act. Work affecting a shared wall is governed by your title deeds and the general law, and in flats by the Tenements (Scotland) Act 2004, so it is sensible to agree the work with neighbours in writing before starting.

Garage conversion openings in Broxburn: your questions

What happens at the survey visit in Broxburn?

We look at the wall, the floor and ceiling either side and what sits above, measure the opening you want, and note cables, pipes and access for the steel. It usually takes under an hour and there is no charge.

How much do garage conversion openings cost in Broxburn?

As a guide, budget £910–£2,730 including VAT for garage door opening infill (structural part) in Broxburn, based on published UK cost guides adjusted for prices in Scotland (-9%). The exact figure depends on the span, what the wall carries, access and the finish, and is fixed in writing once the scope is agreed.

Do I need building regulations for a garage conversion?

Yes. Turning a garage into living space needs a building warrant, covering structure, foundations for the infill, insulation, ventilation, fire safety, escape and damp proofing. In Scotland a building warrant is required before work starts, and in Northern Ireland an application goes to the council's building standards. We handle the building standards application for the structural work.

How long do the structural works for a garage conversion take?

Typically one to two weeks for the structural stage: digging and concreting the infill foundation, building the infill wall, and forming any new opening into the house. Building standards inspections fit around these stages, and the insulation, electrics, plastering and flooring of the conversion follow on afterwards.

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 standards. If any of the garage stays as storage, the opening needs fire separation, such as a fire door.

Can I stay at home while the work is done in Broxburn?

Usually, yes. The work area is screened and floors are protected. The rooms either side of the opening are out of action for a few days, and there is some noise and dust while the masonry comes out.
