Planning steel goalpost frames in St Austell
If you live in St Austell, steel goalpost frames can usually be planned and priced after a single survey visit. The wider Cornwall area is covered as well. We cover PL24, PL25 and PL26, 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.
Key points for your project
- 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.
- 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.
- 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.
From survey to sign-off in St Austell
Free visit
A short visit to St Austell to see the job, agree what you want and check the bearings, floors and services that affect the design.
Calculations
The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.
Building control
We submit a building notice or full plans application to Cornwall Council, so approval is in place before the wall is touched.
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 St Austell
Structural openings in English homes need building regulations approval before work starts. Cornwall Council 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 I stay at home while the work is done in St Austell?
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.
Do you cover St Austell for steel goalpost frames?
Yes. We carry out steel goalpost frames in St Austell and the PL24, PL25 and PL26 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 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.
How long does it take to install a steel goalpost?
Allow around one to two weeks on site for a typical job. Breaking out and digging the pads, the foundation inspection, pouring concrete and letting it gain strength take up much of that time. Erecting and bolting the frame itself is often done in a day, followed by inspection and boxing in.
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.
