About our garage conversion openings service in Craigavon
Craigavon has a mix of housing, and garage conversion openings need a slightly different approach in each. We also cover the surrounding towns and villages in Armagh City, Banbridge and Craigavon. Whatever the age of the property, the steel goes in on proper bearings with temporary support in place throughout.
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.
Key points for your project
- 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.
- 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.
- 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.
- The beam or lintel over a garage door was designed to span an open gap. It may be timber, concrete or steel, and in older houses it can be undersized or corroded, so the engineer checks it before anything is built underneath or above it.
What happens, step by step
Survey in Craigavon
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.
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.
Building control
A full plans application or building notice goes to Armagh City, Banbridge and Craigavon Borough Council under the Building Regulations (Northern Ireland) 2012 before work begins.
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.

Building control and neighbours in Craigavon
Removing a load-bearing wall in Northern Ireland needs building control approval from the council. Armagh City, Banbridge and Craigavon Borough Council covers Craigavon. 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.
Local questions answered
Do I need a party wall agreement for garage conversion openings in Craigavon?
There is no Party Wall Act in Northern Ireland. Your title deeds and the general law apply instead, so agree the work with your neighbour in writing before it starts.
Do you cover Craigavon for garage conversion openings?
Yes. We carry out garage conversion openings in Craigavon and the BT63, BT64, BT65 and BT66 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.
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.
What happens to the beam over my garage door?
It is checked by the engineer. Many can stay, carrying the wall above as before, with the infill built underneath. If it is timber that has rotted, a corroded steel section or simply undersized for the loads, it is replaced, with the wall or room above propped while the new steel goes in.
Does the infill wall need foundations?
Yes. A new masonry wall across the garage door opening needs a proper footing, as the existing garage slab is usually not designed to carry it. A trench is dug across the opening and a foundation is formed to the engineer's and building control's requirements, then inspected before the wall is built.
Can you work on older or listed homes in Craigavon?
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.
