What steel goalpost frames involve in Cambridge
Cambridge has a mix of housing, and steel goalpost frames need a slightly different approach in each. We also cover the surrounding towns and villages in Cambridgeshire. Whatever the age of the property, the steel goes in on proper bearings with temporary support in place throughout.
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.
Things to plan for
- Each column usually needs its own concrete pad foundation, because a column delivers a heavy point load that an ordinary floor slab or old strip footing may not take. The engineer sets the pad size and depth from the load and the ground conditions found.
- A goalpost frame is structural work, so building regulations approval is needed in England and Wales, a building warrant before work in Scotland, and a building control application in Northern Ireland. The inspector typically wants to see the pad excavations as well as the finished steel.
- 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.
- 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.
How the job runs in Cambridge
Survey in Cambridge
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.
How much should I budget in Cambridge?
As a guide, budget £2,100–£6,350 including VAT for steel goalpost frame in Cambridge, based on published UK cost guides adjusted for prices in the East of England (+6%).
| Job | Typical guide range | What it usually covers |
|---|---|---|
| Steel goalpost frame | £2,100–£6,350 | Two posts and a beam bolted as a frame, pad foundations, base plates and fitting |
| Structural calculations for a beam | £260–£800 | Site measure or photos, beam and padstone design and calculations for building control |
| Steel column or post | £530–£1,590 per column | Column supplied and fitted with base and cap plates on a pad foundation |
| Opening into a rear extension | £2,650–£7,400 | Original rear wall removed with a beam or goalpost, approvals and propping, coordinated with the extension build |

Approvals in Cambridge
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.
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.

Questions about steel goalpost frames in Cambridge
What happens at the survey visit in Cambridge?
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.
Do I need a party wall agreement for steel goalpost frames in Cambridge?
Yes, if the beam bears into a shared wall: the Party Wall etc. Act 1996 applies in England and Wales, and a party structure notice must be served at least two months before that work starts. We arrange it through a party wall surveyor.
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.
When do you need a goalpost instead of a steel beam?
You need a goalpost when the walls at either end of the opening cannot safely carry the beam. That happens when piers are too narrow, the masonry is weak or cracked, the opening runs almost wall to wall, or the footings below are unsuitable. The structural engineer makes the call after looking at the loads and the bearings available.
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.
How much do steel goalpost frames cost in Cambridge?
As a guide, budget £2,100–£6,350 including VAT for steel goalpost frame in Cambridge, based on published UK cost guides adjusted for prices in the East of England (+6%). 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.
