Steel beam installation, rsj and structural alterations in Hendon. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs RSJs and steel beams throughout Hendon, from the 1930s semi-detached houses off the main NW4 roads to the mansion blocks near Brent Cross. With more than 30 years of structural experience across Barnet, we remove load-bearing walls safely and open up these generous interwar plans for modern family living.

Hendon's 1930s semis were built with solid or early cavity brick walls and a fairly compartmentalised layout, so almost any wall you want to lose between the front and back reception is doing structural work. Before we touch it, a structural engineer calculates the load and specifies the beam, whether that is a single RSJ or a goalpost frame, along with the padstones the ends bear onto.
We then set up temporary propping, take the wall down in careful stages, and lift the steel into position onto its padstones. Everything is checked and signed off by building control under the Building Regulations. On a typical Hendon semi the beam carries the floor above and, on the flank wall, part of the roof, so the padstone bearing has to be exactly as the engineer drew it.
Because so many Hendon houses are semi-detached, the wall between you and your neighbour is a shared party wall, and the chimney breasts and stacks often sit within it. Where your steelwork bears into or cuts into that wall, the Party Wall Act applies and your neighbour must be served the correct notice before work starts. We flag this early so the notice period does not hold up the build.
For a mid-terrace or an end-of-terrace property near Golders Green or Finchley the same principle holds on the adjoining flank. We coordinate the propping, the engineer's details and the notice timing so the structural opening proceeds cleanly. Getting the party wall paperwork right protects both households and keeps the project on programme rather than stalling at the demolition stage.
Hendon homeowners choose GS Renovation because one team manages the engineer's calculations, the propping, the safe demolition and the building control sign-off. We understand how these 1930s semis and NW4 mansion blocks are built, we handle party wall notices on shared walls, and 30+ years in Barnet means the steel goes in right the first time.
George was brilliant. Lovely bloke, very reasonably priced and a perfectionist to boot. He completed our small kitchen renovation with care and great attention to detail. I've already recommended him to others.
Splendid job on our new kitchen refurb, including new flooring, moving the services, installing RSJ and preparing space for new back doors… George was always friendly, communicative and has an excellent attention to detail, ensuring everything is finished to a high standard.
Giorgio is an excellent and intelligent workman, and with very reasonable prices!… He paid a lot of attention to detail that is not common at all, and the final result was immaculate. Highly recommended!
FAQ
We price each Hendon project individually, because the cost of RSJ and steel beam installation depends on far more than floor area. After a free survey you receive a clear written breakdown with no hidden extras. Call 07472 424 226 or email info@gsrenovationltd.co.uk. As a rough guide, RSJ and steel beam installation in London runs roughly £1,500 to £4,000 for the beam itself on a single straightforward opening, covering supply, installation and building control sign-off; a full knock-through including taking the wall out, the structural engineer's fee and making good more typically comes to £2,500 to £6,500 or more (indicative London ranges, MyBuilder and Checkatrade, 2026). Your figure depends on the size, specification and condition of the property, which is why we survey before quoting.
A straightforward Hendon project can be done in a couple of weeks, while a larger RSJ and steel beam installation with structural work runs longer. We set out a realistic, stage-by-stage programme before we begin so there are no surprises.
Because we manage every trade in-house, your Hendon project stays consistent and accountable from first fix to finish. Add transparent pricing, full insurance and real aftercare, and it is easy to see why Hendon clients recommend us.
Removing a load-bearing wall in Hendon does not normally need planning permission, but it always needs building regulations approval, a structural engineer's calculations and building control sign-off. Where the wall is shared with a neighbour, the Party Wall Act may also apply. We manage all of it.
Yes. A large share of Hendon's homes are 1930s and interwar properties, and we renovate them regularly. We plan each RSJ and steel beam installation around their particular characteristics, such as cavity walls, regular original layouts and the generous plots that suit extending, so the result suits the building and meets building control.
Usually yes. In a Hendon semi the dividing wall with your neighbour is a party wall, so if your steel bears into or cuts that shared wall the Party Wall Act applies and your neighbour must be served notice before work begins. We arrange the structural engineer's design and the notice together so the beam installation stays on schedule.
Yes, Hendon is one of our core areas. We work on every street and the NW4 area and across the wider North London, so wherever your home is, call 07472 424 226 and we will confirm we can help.
