Planning shop & commercial openings in Castlereagh

Shop & commercial openings in Castlereagh are planned around the house, not a standard kit. The wider Belfast area is covered as well. We visit, measure and check what the wall carries, then arrange calculations and building control approval before any steel is ordered.

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.

What to expect

  • 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.
  • Supporting a shopfront means temporary works right at the street edge. Permission from the highway authority may be needed for hoarding, scaffolding or a lifting vehicle on the pavement, and props are positioned so the public route stays safe.
  • Commercial buildings built before 2000 should already have an asbestos register under the duty to manage. Before walls or ceilings are opened up, the register is checked and a refurbishment survey of the work area is arranged where it does not cover the job.
  • The main cost factors are the span and load above, whether columns or a goalpost frame are needed, the temporary works at the street, out-of-hours working, lifting equipment, and the fire protection and finish the opening requires.
  • 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.

  1. Free visit

    A short visit to Castlereagh to see the job, agree what you want and check the bearings, floors and services that affect the design.

  2. Calculations

    The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.

  3. Building control

    A full plans application or building notice goes to Belfast City Council under the Building Regulations (Northern Ireland) 2012 before work begins.

  4. 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 Castlereagh

Removing a load-bearing wall in Northern Ireland needs building control approval from the council. Belfast City Council covers Castlereagh. 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 shop & commercial openings in Castlereagh

What happens at the survey visit in Castlereagh?

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.

Can you work on older or listed homes in Castlereagh?

Yes. Older homes often have lime mortar, timber lintels or shallow footings, which the engineer allows for. Listed buildings need listed building consent for internal structural changes as well as building regulations approval, and that must be in place first.

How does fire safety change when two units are joined?

It can change significantly. The wall between the units may have been a compartment wall, escape routes and travel distances alter, and the new steel needs fire protection to the required period. Building control assesses this as part of the application, and the fire risk assessment for the premises should be updated for the new layout.

Do I need planning permission for a new shop front?

Often, yes. A new or altered shopfront usually changes how the building looks from the street, which can need planning permission, especially in a conservation area. Purely internal openings generally do not, but listed buildings need listed building consent for structural changes inside or out. It is worth checking with the local planning authority early.

Do I need my landlord's permission to put in a steel beam?

Almost certainly, if you lease the premises. Most commercial leases forbid structural alterations without the landlord's written consent, usually given as a licence for alterations. We can supply the engineer's calculations and drawings your landlord asks for, though the lease terms themselves are a matter for you and your solicitor.
