GS Renovation installs RSJs and steel beams across Twickenham, working in the bay-fronted Victorian and Edwardian terraces that line TW1 near the River Thames. With over 30 years of structural experience, we remove load-bearing walls safely, size every beam with a structural engineer and see the work through building control from start to finish.
Removing load-bearing walls in Twickenham
Most Twickenham terraces were built with solid brick walls, so the dividing wall between the front and middle reception is usually load-bearing and carries the floors and roof above. Before anything comes down, we have a structural engineer size the RSJ, then set out temporary propping to support the structure while we open up the wall in careful, staged sections. Nothing is rushed, and the load is always held.
The beam bears onto padstones, typically concrete or high-strength masonry, spread to carry the point loads down through the existing brickwork. In these period houses the chimney breast and stack often need support too, which changes how the steel is arranged. We handle the dust sheeting, the muck away and the making good, so an occupied TW1 home stays liveable while the structural work goes in.
Party wall notices for Twickenham terraces
Because Twickenham's terraces share a party wall with the neighbours on both sides, cutting a beam pocket or bearing steel into that shared wall brings the Party Wall Act into play. We flag this early, so you can serve the correct notice on adjoining owners in good time and avoid the delays that catch people out. Getting the paperwork moving at the start keeps the build on schedule.
Every structural opening we carry out is notified to building control and signed off on completion, giving you the certificate you will want when you eventually sell. We work to the engineer's drawings and calculations, arrange the inspections at the right stages and keep a clear record. That matters in a sought-after TW1 market where buyers and their surveyors ask to see proof that steelwork was done properly.
Checking the steel before it goes in
A beam is checked twice before it is lifted, and it is worth knowing what is being looked at. The first check is against the engineer's drawing: the section size and grade, the overall length, and the position of any holes, cleats or plates already welded on. A section that is fifty millimetres short loses bearing at one end, and that is far easier to discover on the pavement than after it is in the opening.
The second check is the fabrication itself. Steelwork for a domestic beam should come from a fabricator working to the recognised execution standards, with the paperwork to show it, and welded connections should be sound and properly finished rather than tacked. We look at the welds, the drilling and the protective coating on delivery. Anything that does not match the drawing goes back rather than being adapted on site with a grinder to make it fit the opening.
