What load-bearing wall removal involves in Lisburn
If you live in Lisburn, load-bearing wall removal can usually be planned and priced after a single survey visit. The wider Lisburn and Castlereagh area is covered as well. We cover BT17, BT27 and BT28, and we fix the price in writing once the layout and scope are agreed.
We handle the whole job: a survey visit, structural calculations from a qualified engineer, building control, temporary propping, the steel itself, and making good afterwards. You get one itemised written quote and one team to deal with from first visit to sign-off.
What to expect
- The beam size depends on the span, what sits above and how the ends are supported. Two walls that look the same can need very different steel, which is why every beam is sized from calculations rather than guessed.
- Cables, pipes, radiators and sometimes gas runs pass through internal walls. These are traced at the survey so they can be rerouted by the right trade before or during the work, not discovered halfway through.
- A beam can sit below the ceiling with a small boxed downstand or be set up into the floor void so the ceiling runs flat. A flush beam usually needs more work to the joists and costs more.
- Steel beams in homes usually need fire protection. That is often fire-rated plasterboard boxing, which also gives a neat finish, or intumescent paint where the steel is left on show.
- Homes built before 2000 may contain asbestos in textured ceilings, boxing or old boards. Where there is a risk, a survey of the area being disturbed is arranged before the wall comes out.
How the job runs in Lisburn
Free visit
A short visit to Lisburn 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 Lisburn and Castlereagh City 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.

Approvals in Lisburn
Building control in Lisburn is run by Lisburn and Castlereagh City Council. Beams and new openings are controlled work under the Northern Ireland regulations, so we apply before anything is removed and the steel is inspected before it is covered.
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
Can you work on older or listed homes in Lisburn?
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.
How soon can load-bearing wall removal start in Lisburn?
Start dates depend on the engineer's calculations, the building control approval and any agreement needed with neighbours. We give you a realistic timetable after the survey and keep you updated as each approval comes through.
Will the beam show once the job is finished?
It depends on the design. Most beams sit just below the ceiling and are boxed in with plasterboard, leaving a small step. A beam can be set up into the floor void for a flat ceiling, which takes more work, or left exposed and painted where you want an industrial look.
Do I need planning permission to remove an internal wall?
Usually not, because internal alterations to a house are not normally development needing planning permission. Listed buildings are different and need listed building consent, and flats normally need the freeholder's or landlord's written consent.
Who sizes the steel beam?
A structural engineer. They look at the span, the loads from floors, walls and roof above, and the bearings at each end, then specify the beam, padstones and any columns. We arrange those calculations, or work to calculations you already have.
Do I need a party wall agreement for load-bearing wall removal 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.
