About our steel goalpost frames service in West Sussex
A steel goalpost frame is a beam supported on two steel columns, bolted together into one rigid unit shaped like a goalpost. It is used where the masonry either side of an opening cannot take the beam's load, or where a wide opening leaves little wall to bear on. The columns stand on base plates fixed to concrete pad foundations sized by the engineer.
From the first survey visit to the completion certificate, we take care of steel goalpost frames across West Sussex. Towns we cover include Horsham, East Grinstead and Burgess Hill, among other places in the area. The engineer sizes the steel, we deal with building control, and our team fits and packs the beam before making good.
Things to plan for
- 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.
- 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.
- Price depends on the opening width, the loads the beam carries, the number of bolted connections, the depth of the pads and how easily the steel can be carried in. Any redesign after the ground is opened is priced before it goes ahead.
- 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.
- 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.
What happens, step by step
Survey in West Sussex
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.
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.
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.
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 West Sussex
Structural openings in English homes need building regulations approval before work starts. The local council's building control team can deal with it, or you can use a registered building control approver. Either way the steel is inspected before it is covered, and a completion certificate is issued at the end. Keep it safe for when you sell.
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
Can you work on older or listed homes in West Sussex?
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 much do steel goalpost frames cost in West Sussex?
As a guide, budget £2,250–£6,700 including VAT for steel goalpost frame in West Sussex, based on published UK cost guides adjusted for prices in the South East (+12%). The exact figure depends on the span, what the wall carries, access and the finish, and is fixed in writing once the scope is agreed.
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.
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.
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.
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.
Can I stay at home while the work is done in West Sussex?
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.
