What steel goalpost frames involve in Acton

If you live in Acton, steel goalpost frames can usually be planned and priced after a single survey visit. We also cover the surrounding towns and villages in London. We cover NW10, TW8, W3, W4 and W5, and we fix the price in writing once the layout and scope are agreed.

When a rear wall is opened almost corner to corner, or the brickwork either side is too thin, cracked or broken up by openings to take a concentrated load, a beam on padstones is not enough. A goalpost frame brings its own supports: two columns carry the beam's ends straight down to new foundations, so the walls around the opening are not relied on.

Worth knowing before you start

  • 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.
  • Column pads can clash with drains, gas pipes and underfloor heating runs below the floor. These are located before digging, and if a drain runs where a pad needs to go, the engineer may move the column or redesign the pad.
  • Goalpost frames are made to measure, so accurate site dimensions matter. Floor-to-ceiling height, the finished floor level and the width between column positions are taken before fabrication, because a frame that is a few millimetres out cannot simply be trimmed on site.
  • Digging the column pads means breaking through the floor, which is noisier and messier than fitting a beam alone. Floor coverings near the column positions need lifting, and the spoil from the excavations is bagged and removed from site.
  • While the old wall or piers come out, the floor, walls and roof above are held on props and needles. These stay in until the frame is fully bolted, levelled and packed, so the structure is never left without support.

What happens, step by step

  1. Survey in Acton

    We visit, look at the wall and what sits above it, measure the opening and note services, access and how the steel can be brought in.

  2. Engineer's design

    A structural engineer sizes the beam, padstones and any posts, and sets out the temporary support needed while the wall is out.

  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. Install and sign-off

    Props go in, the opening is formed, the steel is set and packed, building control inspects it, and we make good.

Building rules for Acton

For Acton, 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.

If the beam bears into a wall you share with a neighbour, the Party Wall etc. Act 1996 applies, and a party structure notice must be served at least two months before that work starts. We arrange this through a party wall surveyor.

Steel goalpost frames in Acton: your questions

Do you cover Acton for steel goalpost frames?

Yes. We carry out steel goalpost frames in Acton and the NW10, TW8, W3, W4 and W5 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.

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

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.

Can a goalpost frame be hidden?

Usually, yes. The columns can be boxed in with fire-rated plasterboard so they read as small piers, set inside new walls, or hidden within the line of an extension's side walls. The beam is boxed like any other steel. Some owners prefer to leave the frame exposed and painted as a design feature.

Do I need building regulations approval for a goalpost frame?

Yes. Installing a goalpost frame is structural building work. In England it needs building regulations approval through a full plans application or building notice, in Wales an application under the Welsh regulations, in Scotland a building warrant must be granted first, and in Northern Ireland the council's building control is applied to before work begins. We arrange the application and inspections.

What is a goalpost frame in an extension?

A goalpost frame is a steel beam sitting on two steel columns, bolted together so it stands as one unit. In an extension it is usually placed where the old rear wall was, holding up the house above while leaving a wide, clear opening. The columns rest on concrete pads, so the frame does not depend on the surrounding brickwork.
