What steel goalpost frames involve in Llandudno
Llandudno has a mix of housing, and steel goalpost frames need a slightly different approach in each. The wider Conwy area is covered as well. 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
- 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.
- 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.
- 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.
- 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.
- Columns are commonly universal columns or square hollow sections, welded to steel base plates at the foot and cap plates at the head. Holding-down bolts fix the base plates to the pad, and grout fills the gap beneath once the frame is level.

Approvals in Llandudno
In Wales, structural alterations come under the Building Regulations 2010 as they apply in Wales. Conwy County Borough Council handles building control for Llandudno. For work started or approved from 1 July 2026, the Welsh system uses an application to building control, dutyholders appointed in writing, a commencement notice before work starts and a compliance statement at the end.
The Party Wall etc. Act 1996 applies in Wales as well as England, so a beam bearing into a shared wall needs a party structure notice at least two months before work starts. We arrange notices through a party wall surveyor.

Local questions answered
Do you cover Llandudno for steel goalpost frames?
Yes. We carry out steel goalpost frames in Llandudno and the LL30 and LL31 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.
How soon can steel goalpost frames start in Llandudno?
Start dates depend on the engineer's calculations, the building control approval and, where needed, party wall notice periods. We give you a realistic timetable after the survey and keep you updated as each approval comes through.
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.
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.
Is a goalpost frame more expensive than a beam?
Generally yes, because there is more steel, more fabrication and new foundations to dig and pour. Against that, a goalpost can avoid rebuilding weak piers or strengthening walls so they can take a beam. Our itemised written quote shows the frame, pads, propping and making good separately so you can see where the cost sits.
Can you work on older or listed homes in Llandudno?
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.
