Planning steel goalpost frames in Amlwch
For homes in Amlwch and the LL66, LL68, LL69 and LL70 districts, we handle steel goalpost frames from survey to sign-off. We also cover the surrounding towns and villages in Anglesey. The beam is sized by a structural engineer and inspected before it is boxed in.
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
- 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.
- Column pads can clash with drains, gas pipes and underfloor heating runs below the floor. These are located before digging, and if a drain runs where a pad needs to go, the engineer may move the column or redesign the pad.
- 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.
- 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.
- 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.

Local questions answered
How much do steel goalpost frames cost in Amlwch?
As a guide, budget £1,800–£5,450 including VAT for steel goalpost frame in Amlwch, based on published UK cost guides adjusted for prices in Wales (-9%). 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.
Do you also work near Amlwch?
Yes. We also cover nearby towns including Llangefni, Holyhead, Menai Bridge and Bangor.
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.
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.
Do I need a party wall agreement for steel goalpost frames in Amlwch?
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.
