About our kitchen-diner knock-throughs service in Lisburn
We carry out kitchen-diner knock-throughs in Lisburn, covering the BT17, BT27 and BT28 postcode districts. The wider Lisburn and Castlereagh area is covered as well. The job starts with a free survey visit so the engineer's calculations are based on your actual walls, floors and loads.
We plan the structural work alongside your kitchen design so the beam, any column and the services all land in the right place before units are ordered. A survey visit, engineer's calculations, building control, propping, the steel and making good are all covered in one itemised written quote, with the price fixed in writing once the layout and specification are agreed.
Worth knowing before you start
- Cooker hood ducting that currently runs out through the wall may need a new route once the wall goes. Ducting can often be run in the ceiling void alongside the beam, but the beam's position and depth need to be known first.
- Sinks and dishwashers usually sit on an outside wall, but supply pipes and waste runs sometimes cross the internal wall. Moving the sink to an island means planning a waste route with enough fall under the floor, which affects how the floor is prepared.
- 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.
- Keep the structural calculations, the building control completion certificate and any gas or electrical certificates together. When the house is sold, the buyer's solicitor will usually ask for evidence that the knock-through was approved and signed off.
- Settle the kitchen layout before the steel is designed. If the engineer needs a column or a deeper beam, it is far easier to plan an island, tall units or the hob position around it at drawing stage than after the units are ordered.
What happens, step by step
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 Lisburn and Castlereagh City 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.

Approvals in Lisburn
Removing a load-bearing wall in Northern Ireland needs building control approval from the council. Lisburn and Castlereagh City Council covers Lisburn. The engineer's calculations support the application, and a completion certificate is issued after the final inspection.
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 kitchen-diner knock-throughs in Lisburn
Do you also work near Lisburn?
Yes. We also cover nearby towns including Castlereagh, Newtownabbey, Newtownards and Craigavon.
Do I need a party wall agreement for kitchen-diner knock-throughs 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.
Can I have a kitchen island where the wall used to be?
Often you can, but it depends on whether the engineer needs a column and where the beam ends bear. If an island is part of the plan, tell us at the survey so the steel can be designed around it. Plumbing or power to an island also needs a route under the floor.
How long will I be without a kitchen?
The structural work itself usually takes three to six working days, and the kitchen is out of action during that time. After that come plastering, drying, flooring and the kitchen fit, so the overall period without a finished kitchen depends mostly on your fitter's programme and when the units are delivered.
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 Lisburn?
Structural work in Lisburn needs a full plans application or building notice to Lisburn and Castlereagh City Council. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.
