What through-lounge knock-throughs involve in Armagh City, Banbridge and Craigavon
Across Armagh City, Banbridge and Craigavon, through-lounge knock-throughs usually come up when people want more light, a better layout or a way through to a new extension. Towns we cover include Portadown, Craigavon and Banbridge, among other places in the area. Whatever the reason, the beam is sized from calculations and the work is inspected before anything is covered.
Worth knowing before you start
- Victorian brickwork is usually laid in soft lime mortar and the internal walls may be only one brick thick. The engineer allows for this when designing the bearings, and padstones are often used to spread the beam's load over the weaker masonry.
- With the wall gone, the floorboards on each side may run in different directions or sit at slightly different heights. Matching reclaimed boards can be fitted across the old wall line, or the floor can be levelled for a new continuous finish.
- Minor hairline cracks can appear in plaster upstairs as the structure takes up the new support. This is common after a knock-through and is usually filled at decoration stage, but wider or growing cracks should be reported so they can be checked.
- In most terraced houses the wall between the front and back rooms runs across the house and carries the floor above, plus the wall between the front and back bedrooms. It is normally load-bearing, but the engineer still checks before any design is drawn up.
- Period ceilings are often lath and plaster, which can crack or sag when the wall below is disturbed. Props are set to spread load gently, and damaged areas are repaired with lime plaster or overboarded, depending on the condition and your preference.

Questions about through-lounge knock-throughs in Armagh City, Banbridge and Craigavon
Can I stay at home while the work is done in Armagh City, Banbridge and Craigavon?
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.
Which towns in Armagh City, Banbridge and Craigavon do you cover?
We cover towns including Craigavon, Portadown and Banbridge, plus the villages and smaller towns around them.
Will the ceiling crack when the wall is removed?
Some minor cracking in old lath and plaster ceilings is possible, even with careful propping, because the structure is being disturbed. We prop to spread the load and protect ceilings where we can, and any cracks are filled or repaired as part of making good. Sound plaster normally stays intact.
Can I keep the cornicing when the wall comes down?
Usually yes. The existing cornice in each room is protected during the work, and a matching profile can be run or cast to bridge the opening once the beam is boxed and plastered. How closely it matches depends on the original design and its condition, which we check at the survey visit.
Do I need consent to knock through in a listed building?
Yes, you need both listed building consent and building regulations approval. Listed building consent from the local planning authority covers internal structural changes to the building's fabric, and building control covers the structural safety. Carrying out works to a listed building without consent is an offence, so it must be in place before anything is booked.
Is the wall between two reception rooms load-bearing?
In most period terraces and semis it is, because it carries the floor joists and the wall between the bedrooms above. Some later houses have lighter partitions in this position, so the only way to be sure is an engineer's inspection. We arrange this during the survey and design stage.
