Steel goalpost frames in Llanelli: how it works
Planning steel goalpost frames in Llanelli? Our team covers SA15 and the streets around them. Our coverage runs across Carmarthenshire, so nearby villages are included too. You get one written quote for the calculations, approvals, propping, steel and making good.
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.
Things to plan for
- 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.
- A goalpost frame usually takes longer than a single beam because the pads need digging, inspecting, pouring and time to gain strength before the columns take load. The engineer sets when the frame can be loaded.
- 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.
- 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.
- 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.
Four stages, one team
Free visit
A short visit to Llanelli 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 the application or notice to Carmarthenshire County Council under the Building Regulations as they apply in Wales, before work starts.
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.

| Job | Typical guide range | What it usually covers |
|---|---|---|
| Steel goalpost frame | £1,800–£5,450 | Two posts and a beam bolted as a frame, pad foundations, base plates and fitting |
| Side return extension steelwork | £3,200–£7,750 | Beams and posts along the old side wall line, propping and approvals (extension build extra) |
| Structural calculations for a beam | £230–£680 | Site measure or photos, beam and padstone design and calculations for building control |
| Rear wall opening for bi-fold or sliding doors | £2,300–£6,350 | External wall opened up to about 5 m with steel, propping, cavity tray and making good (doors supplied separately) |
Figures include our approximate regional adjustment for prices in Wales (-9%) and are rounded. How these figures are worked out.
Building control and neighbours in Llanelli
Welsh building regulations treat beams and new openings as controlled building work. We apply to Carmarthenshire County Council on your behalf before anything is removed, give the commencement notice the 2026 Welsh rules require, and the steel is checked before it is boxed in.
Where the steel bears into a wall shared with next door, notice must be served under the Party Wall etc. Act 1996. If your neighbour dissents, surveyors agree how the work is done before it starts.

Local questions answered
Can you work on older or listed homes in Llanelli?
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.
Can I stay at home while the work is done in Llanelli?
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.
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.
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 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 a party wall agreement for steel goalpost frames in Llanelli?
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.
