Steel goalpost frames in Croydon: how it works

For homes in Croydon and the CR0, CR2, CR7, CR9 and SE19 districts, we handle steel goalpost frames from survey to sign-off. We also cover the surrounding towns and villages in London. The beam is sized by a structural engineer and inspected before it is boxed in.

We arrange the engineer's design, building control, the foundation pads, temporary propping and the fabricated frame, then box it in and make good. Everything is set out in one itemised written quote, and the price is fixed in writing once the layout and specification are agreed.

Key points for your project

  • Columns can be boxed in with fire-rated plasterboard to look like small piers, built into new stud walls, or left exposed and painted. Where an extension wall continues past the opening, a column can often sit within it out of sight.
  • Keep the engineer's calculations, the frame drawings and the building control completion certificate together. They show a future buyer's surveyor how the opening is supported and save questions about the columns when the house is sold.
  • In older homes with suspended timber ground floors, the column has to pass through the void to reach the pad. Air bricks, joists and the damp-proof course around each column are considered so ventilation and damp protection are not compromised.
  • A goalpost frame differs from a simple beam because the beam does not rely on the walls at its ends. The two columns and the beam are connected so the whole frame carries the load down into foundations of its own.
  • Columns are commonly universal columns or square hollow sections, welded to steel base plates at the foot and cap plates at the head. Holding-down bolts fix the base plates to the pad, and grout fills the gap beneath once the frame is level.

Four stages, one team

  1. Free visit

    A short visit to Croydon 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 rules for Croydon

In England, taking out a load-bearing wall or putting in a beam is building work under the Building Regulations 2010. It needs approval from building control, either the local council's building control team or a registered building control approver, through a full plans application or a building notice. Part A covers the structure and Part B covers fire safety, which is why steel in homes is usually fire protected.

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.

Questions about steel goalpost frames in Croydon

Do you also work near Croydon?

Yes. We also cover nearby towns including South Croydon, Wallington, Carshalton and Mitcham.

Can you work on older or listed homes in Croydon?

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.

What is the difference between a goalpost and a portal frame?

A domestic goalpost is a simple version of a portal frame. Both use columns and a beam joined together, but a full portal frame has rigid joints designed to resist sideways loads on its own, as used in steel-framed industrial buildings. In a house, the engineer decides how rigid the goalpost joints need to be for that opening.

Can a goalpost column go next to my neighbour's wall?

It can, but in England and Wales it may bring in the Party Wall etc. Act 1996. Digging a pad near a neighbour's building to below the level of its foundations, or fixing into a shared wall, can be notifiable. We arrange notices through a party wall surveyor where needed. There is no equivalent Act in Scotland or Northern Ireland.

Does a goalpost frame need foundations?

Yes, in most cases each column needs a concrete pad foundation beneath it. A column concentrates a lot of weight on a small area, and a normal floor slab is rarely designed for that. The engineer sizes each pad, and building control usually inspects the excavation before the concrete goes in.
