Garage conversion openings in Dungannon: how it works
For homes in Dungannon and the BT71 district, we handle garage conversion openings from survey to sign-off. The wider Mid Ulster area is covered as well. The beam is sized by a structural engineer and inspected before it is boxed in.
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
- 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.
- Garage floors often sit lower than the house floor and may have no damp-proof membrane. The infill wall needs a damp-proof course linked to the existing walls, and the floor usually needs a membrane, insulation and screed raised to the house level.
- 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.
- 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.
Four stages, one team
Free visit
A short visit to Dungannon to see the job, agree what you want and check the bearings, floors and services that affect the design.
Calculations
The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.
Building control
A full plans application or building notice goes to Mid Ulster District Council under the Building Regulations (Northern Ireland) 2012 before work begins.
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 Dungannon
Removing a load-bearing wall in Northern Ireland needs building control approval from the council. Mid Ulster District Council covers Dungannon. The engineer's calculations support the application, and a completion certificate is issued after the final inspection.
The Party Wall etc. Act does not extend to Northern Ireland. Shared walls are dealt with under your title and the general law, so we recommend agreeing access and the work with your neighbour before it starts.
Garage conversion openings in Dungannon: your questions
Do you also work near Dungannon?
Yes. We also cover nearby towns including Cookstown, Portadown, Craigavon and Magherafelt.
Can you work on older or listed homes in Dungannon?
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.
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.
Do I need a steel beam for a garage conversion?
Not always. If the existing beam over the garage door is sound and the infill wall sits on its own foundation, new steel may not be needed. Steel is usually required when forming an opening through a load-bearing wall into the house, or when the garage door beam is undersized or corroded. The engineer decides.
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.
Can I stay at home while the work is done in Dungannon?
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.
