Planning wider doorways & openings in Lisburn
For homes in Lisburn and the BT17, BT27 and BT28 districts, we handle wider doorways & openings from survey to sign-off. The wider Lisburn and Castlereagh area is covered as well. The beam is sized by a structural engineer and inspected before it is boxed in.
We arrange a survey visit, structural calculations where the wall is load-bearing, building control, propping, the lintel or beam, new door linings if you want them, and making good. One itemised written quote covers the lot, and the price is fixed in writing once the opening size and finish are agreed.
Things to plan for
- Standard internal doors come in set widths, so it makes sense to size the opening to suit an off-the-shelf door and lining. Odd sizes need made-to-measure doors and linings, which take longer to arrange.
- Openings are cut with a masonry saw where possible rather than broken out with a hammer. Clean cuts keep the brickwork either side sound, give a straighter edge for plastering and send less vibration through the rest of the wall.
- In older houses, a doorway may already have a timber lintel that has rotted or a brick arch that is hard to extend. These are replaced rather than added to, and the engineer allows for soft lime mortar and any cracking found once the wall is opened.
- The main cost factors are whether the wall is structural, the width of the opening, what the support bears onto, how much electrical or heating work has to move, and whether you want new door linings and doors fitted as part of the job.
- Each side of the new opening needs enough solid wall for the lintel or beam to sit on. If the opening runs close to a corner, another doorway or a chimney breast, there may not be enough masonry, and a column or padstone may be required.
From survey to sign-off in Lisburn
Look and measure
We check the wall, the span you want and what the wall is carrying, and photograph anything the engineer needs to see.
Design and price
Calculations come back from the engineer and we confirm your fixed written price, line by line.
Building control
A full plans application or building notice goes to Lisburn and Castlereagh City Council under the Building Regulations (Northern Ireland) 2012 before work begins.
Fit, inspect, finish
The work is propped and the steel installed and packed tight. After inspection the opening is boxed, plastered and left clean.

Wider doorways & openings in Lisburn: your questions
Can I stay at home while the work is done in Lisburn?
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.
Do I need a party wall agreement for wider doorways & openings in Lisburn?
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.
Will widening a doorway make a mess?
There is some dust and noise, mainly on the day the opening is cut. We screen the area, protect floors along the route and use dust extraction on saws where possible. Rooms either side are affected for a day or two, while the rest of the house stays in normal use.
What is included in the price for a wider doorway?
The itemised written quote lists the survey, any engineer's calculations and building control fees, propping, cutting the opening, the lintel or steel, linings or plastered reveals, and making good. Moving services, supplying doors and flooring joins appear as separate lines. The price is fixed in writing once the size and finish are agreed.
Can I move a doorway to a different position?
Usually, yes. The old doorway is blocked up and a new opening is formed with the support the engineer specifies, and both changes are dealt with together for building control if the wall is structural. Moving a door can release wall space for furniture or a better kitchen or bedroom layout.
Who approves wider doorways & openings in Lisburn?
Structural work in Lisburn needs a full plans application or building notice to Lisburn and Castlereagh City Council. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.
