What steel goalpost frames involve in Newtown
We cover steel goalpost frames in Newtown (SY16) and the streets around it. Our coverage runs across Powys, so nearby villages are included too. Each job is designed by a structural engineer and approved through Powys County Council before work begins.
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
- 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.
- 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.
- 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.
- 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.

Building rules for Newtown
In Wales, structural alterations come under the Building Regulations 2010 as they apply in Wales. Powys County Council handles building control for Newtown. 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.
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 Newtown?
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.
Do you cover Newtown for steel goalpost frames?
Yes. We carry out steel goalpost frames in Newtown and the SY16 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.
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.
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.
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.

Yes. We also cover nearby towns including Welshpool and Llandrindod Wells.
