About our through-lounge knock-throughs service in Ards and North Down
We carry out through-lounge knock-throughs throughout Ards and North Down, for homeowners, landlords and builders who need the structural part done properly. Coverage takes in Bangor and Newtownards and everywhere in between. You get an itemised written quote that shows the calculations, approvals, steel, labour and finishing as separate lines.
What to expect
- 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.
- Radiators, pipe runs and sockets on the dividing wall need relocating. Older houses sometimes have heating pipes running under the floor along the wall line, so these are traced and moved by a heating engineer before the wall comes down.
- 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.
- The steel commonly needs fire protection to meet building regulations, usually by boxing it in fire-rated plasterboard and skimming it. In period rooms the box can be finished with a matching cornice so it reads as part of the original ceiling.
- If the house is listed, internal structural alterations need listed building consent as well as building regulations approval. Conservation area status does not usually affect internal work, but flats within converted period houses normally need the freeholder's consent.
Four stages, one team
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 Ards and North Down Borough 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.

Building rules for Ards and North Down
Building control in Ards and North Down is run by Ards and North Down Borough 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.

Questions about through-lounge knock-throughs in Ards and North Down
What happens at the survey visit in Ards and North Down?
We look at the wall, the floor and ceiling either side and what sits above, measure the opening you want, and note cables, pipes and access for the steel. It usually takes under an hour and there is no charge.
Which towns in Ards and North Down do you cover?
We cover towns including Bangor and Newtownards, plus the villages and smaller towns around them.
How wide can a through-lounge opening be?
That depends on what the wall carries and how the beam ends can be supported, and the structural engineer sets it. Many owners go nearly full width, keeping short nibs at each end, while others choose a narrower opening to keep two distinct rooms. Wider spans need heavier steel and sometimes columns.
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.
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.
