Shop & commercial openings in Lisburn: how it works

Lisburn has a mix of housing, and shop & commercial openings need a slightly different approach in each. The wider Lisburn and Castlereagh area is covered as well. Whatever the age of the property, the steel goes in on proper bearings with temporary support in place throughout.

We carry out structural openings for small commercial premises across the UK, working to an engineer's design and handling building control. Work can be planned around opening hours, including out-of-hours shifts where the landlord and building allow, and coordinated with your shopfitter.

Things to plan for

  • Shop buildings commonly have a full-height brick wall above the shopfront carrying upper floors and the roof. The engineer designs for that load, plus any point loads from chimney stacks or columns, and may specify a compound section or a steel frame.
  • Most commercial leases prohibit structural alterations without the landlord's written consent, often given as a licence for alterations. Securing it before work starts avoids disputes later, and we supply the drawings and calculations the landlord or their surveyor asks to see.
  • Commercial premises often have three-phase power, alarm and data cabling, gas supplies and drainage running through the walls being altered. These are mapped at the survey, and any work on gas pipes must by law be done by a Gas Safe registered engineer.
  • Purely internal works may not need planning permission, but a new or altered shopfront changes the look of the building and may need it, particularly in a conservation area. Listed commercial buildings also need listed building consent for structural changes.
  • Joining two units can change the fire strategy. The wall between them may be a compartment wall, escape routes and travel distances alter, and the steel needs fire protection to the required period. The fire risk assessment should be updated to match the new layout.

How the job runs in Lisburn

  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 Lisburn and Castlereagh City 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.

Building control and neighbours 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.

Northern Ireland has no Party Wall Act, so there is no statutory notice to serve. Where the steel bears into a shared wall, the title deeds and the general law apply, and agreeing the work with your neighbour in writing first is good practice.

Local questions answered

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

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.

Do you also work near Lisburn?

Yes. We also cover nearby towns including Castlereagh, Newtownabbey, Newtownards and Craigavon.

What kind of steel is used for a wide shop front?

The engineer chooses the section to suit the span and load. Wide frontages often use universal beams, sometimes paired or plated, and a goalpost frame of two columns and a beam where the existing piers cannot take the load. The steel is then fire protected and finished behind the fascia or boxing.

Does the beam above my shop window need replacing?

Not always, but it should be checked. Many shopfronts sit under an old steel, timber or concrete beam hidden behind the fascia, which may have corroded, rotted or been undersized for the wall above. An engineer inspects it once it is opened up and decides whether it can be kept, strengthened or must be replaced.

Do I need an asbestos survey before work on my shop?

Usually, if the building dates from before 2000. The duty holder for commercial premises should already have an asbestos register, and before walls, ceilings or the shopfront are opened up, a refurbishment survey of the work area is needed wherever that register does not cover it, so any asbestos is dealt with first.

Do I need a party wall agreement for shop & commercial openings 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.
