What steel goalpost frames involve in Canterbury
We cover steel goalpost frames in Canterbury (CT1, CT2) and the streets around it. Our coverage runs across Kent, so nearby villages are included too. Each job is designed by a structural engineer and approved through local building control before work begins.
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
- 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.
- Stability is part of the design, not just strength. A frame standing in a wide opening can sway sideways if the joints are too flexible, so the engineer decides whether the connections must be moment-resisting or whether the frame is tied back to the surrounding structure.
- 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.
- 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.
Four stages, one team
Look and measure
We check the wall, the span you want and what the wall is carrying, and photograph anything the engineer needs to see.
Design and price
Calculations come back from the engineer and we confirm your fixed written price, line by line.
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.
Fit, inspect, finish
The work is propped and the steel installed and packed tight. After inspection the opening is boxed, plastered and left clean.

| Rear wall opening for bi-fold or sliding doors | £2,800–£7,850 | External wall opened up to about 5 m with steel, propping, cavity tray and making good (doors supplied separately) |
| Opening into a rear extension | £2,800–£7,850 | Original rear wall removed with a beam or goalpost, approvals and propping, coordinated with the extension build |

Building rules for Canterbury
For Canterbury, 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.

Questions about steel goalpost frames in Canterbury
Do you also work near Canterbury?
Yes. We also cover nearby towns including Whitstable, Herne Bay, Faversham and Ashford.
Who approves steel goalpost frames in Canterbury?
Structural work in Canterbury needs a building notice or full plans application to the local council's building control team or a registered building control approver. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.
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.
Does a goalpost frame need foundations?
Yes, in most cases each column needs a concrete pad foundation beneath it. A column concentrates a lot of weight on a small area, and a normal floor slab is rarely designed for that. The engineer sizes each pad, and building control usually inspects the excavation before the concrete goes in.
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 happens at the survey visit in Canterbury?
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.
