What kitchen-diner knock-throughs involve in Belfast
Kitchen-diner knock-throughs remove the wall between a kitchen and a dining room to create one open-plan room, with a steel beam carrying whatever the wall supported. The work is planned around the kitchen itself: gas, water, waste and extraction runs, where units and any island will go, and how the ceiling should look once the steel is in.
We carry out kitchen-diner knock-throughs throughout Belfast, for homeowners, landlords and builders who need the structural part done properly. Coverage takes in Castlereagh and everywhere in between. You get an itemised written quote that shows the calculations, approvals, steel, labour and finishing as separate lines.
Things to plan for
- The structural work comes first, then first-fix electrics and plumbing, plastering, flooring and finally the kitchen fit. Booking the kitchen fitter only once the beam has passed inspection and the plaster has dried avoids units going onto damp walls.
- Older kitchens can hide asbestos in textured ceiling coatings, floor tiles, boxing around pipes or the backing of old heaters. In buildings from before 2000 it must be identified before the fabric is disturbed, so a survey of the affected area is arranged first.
- Where the wall stood there is usually a strip of footing or a change in floor level between the two rooms. It is levelled with screed or timber so one continuous floor finish, such as tiles or engineered boards, can run straight across.
- In many houses the kitchen and dining room wall carries the bedroom floor joists, and sometimes a bathroom wall above. Lifting a floorboard upstairs to see which way the joists run is a useful first look, though the engineer confirms what the wall actually supports.
- If the kitchen also opens onto the hallway, the change can affect the escape route from the bedrooms. Building control checks how people would get out in a fire, and smoke alarms, a fire door or other measures may be required as part of approval.
What happens, step by step
Free visit
A short visit to Belfast 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 Belfast 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 Belfast
In Northern Ireland, structural work comes under the Building Regulations (Northern Ireland) 2012 and is approved by the local council's building control. For Belfast that is Belfast City Council. We submit a full plans application or building notice before work starts and book the inspections.
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.
Kitchen-diner knock-throughs by town
Local questions answered
Which towns in Belfast do you cover?
We cover towns including Castlereagh, plus the villages and smaller towns around them.
Do I need a party wall agreement for kitchen-diner knock-throughs in Belfast?
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.
Should I do the knock-through before or after fitting a new kitchen?
Before. The steel, any column, the floor levelling and the plastering all need to be finished first, so the kitchen fitter works in a dry, square room with services already in position. Fitting units and then taking out a wall risks damage and rework, and the beam position can affect where wall units go.
Can I knock my kitchen and dining room into one?
In most houses, yes. The wall can be removed even if it is load-bearing, as long as a steel beam designed by a structural engineer takes over the load and building control approves the work. The main things to check early are what the wall carries, where services run, and whether the layout still works around any column.
Can the steel beam be hidden in the ceiling?
Yes, a flush beam can be set into the ceiling void so there is no step between the kitchen and dining ceilings. It needs enough joist depth and more labour to connect the joists to the steel, so it costs more than a downstand. The engineer confirms whether it is possible in your house.
What does a kitchen-diner knock-through quote include?
Our written quote is itemised: survey, engineer's calculations, building control, propping, removal of the wall, steel and padstones, fire protection, floor levelling and making good, with any gas, plumbing or electrical rerouting listed separately. Once the layout, specification and scope are agreed, the price is fixed in writing.
Who approves kitchen-diner knock-throughs in Belfast?
Structural work in Belfast needs a full plans application or building notice to Belfast City Council. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.
