About our through-lounge knock-throughs service in Banbridge

Many period terraces and semis were built with a front parlour and a back sitting room divided by a solid brick wall. Opening them into one through-lounge brings light from both ends of the house, but that wall commonly carries the floor joists, the wall between the bedrooms above and sometimes part of the roof load too.

Key points for your project

  • Ornate cornicing often runs around both rooms and stops at the wall being removed. Where practical, the run is extended across the opening by matching the profile, either run in place or cast, so the joined room looks original rather than patched.
  • Many owners leave short nibs of wall at each end of the opening rather than going fully wall to wall. Nibs can give the beam a bearing, line up with the chimney breasts and keep the feel of two linked rooms, but the engineer decides whether they are adequate.
  • 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.
  • 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.
  • 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.

How the job runs in Banbridge

  1. 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.

  2. Design and price

    Calculations come back from the engineer and we confirm your fixed written price, line by line.

  3. 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.

  4. Fit, inspect, finish

    The work is propped and the steel installed and packed tight. After inspection the opening is boxed, plastered and left clean.

Approvals in Banbridge

Building control in Banbridge is run by Armagh City, Banbridge and Craigavon 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 Banbridge

Do I need a party wall agreement for through-lounge knock-throughs in Banbridge?

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.

Can I stay at home while the work is done in Banbridge?

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.

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.

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.

Should I keep the chimney breasts when knocking through?

Most people do, because the breasts frame the opening and support the stack above. Removing a chimney breast is a separate structural job needing its own design and approval, and it affects your neighbour if the stack is shared. Keeping them usually simplifies the steelwork and preserves the character of the room.

How soon can through-lounge knock-throughs start in Banbridge?

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.
