Shop & commercial openings in Wood Green: how it works

We cover shop & commercial openings in Wood Green (N4, N8, N10) and the streets around it. We also cover the surrounding towns and villages in London. Each job is designed by a structural engineer and approved through local building control before work begins.

Commercial buildings often have a flat or offices above the shop, a heavy brick front and old steel or timber over the existing shopfront. Opening them up means supporting a lot of load at street level, usually with the public walking past, while keeping disruption to trading as low as possible.

What to expect

  • A straightforward shopfront beam replacement can take a few days on site, while joining two units with several openings may run to a couple of weeks. The programme is agreed in writing before work starts so you can plan trading around it.
  • 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.
  • 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.
  • Many shopfronts sit under an old steel or timber beam hidden behind the fascia for decades. It may be corroded, undersized for what is above or bearing on decayed masonry, so it is opened up and checked before keeping it is even considered.
  • 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.

What happens, step by step

  1. Free visit

    A short visit to Wood Green 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

    We submit a building notice or full plans application to the local council's building control team, so approval is in place before the wall is touched.

  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.

Building control and neighbours in Wood Green

For Wood Green, building control is provided by the local council's building control team, or by a registered building control approver if preferred. We send them the engineer's calculations with a building notice or full plans application and book the inspections. Work done without approval can cause problems at sale and is far dearer to put right later.

Terraced and semi-detached homes often need party wall notices, because cutting into a shared wall to take a beam end is notifiable under the Party Wall etc. Act 1996. Allow at least two months for the notice period unless your neighbour agrees sooner.

Local questions answered

Do you also work near Wood Green?

Yes. We also cover nearby towns including Muswell Hill, Tottenham, Archway and Stamford Hill.

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

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.

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.
