Steel beam installation, rsj and structural alterations in Brixton. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs RSJs and steel beams across Brixton, from the bay-fronted Victorian and Edwardian terraces of SW2 to homes near Brockwell Park. With more than 30 years of structural experience in Lambeth, we size, prop and set every beam correctly, remove load-bearing walls safely and hand over clean building control sign-off.

The dividing wall between the front and middle reception in a Brixton terrace is almost always load-bearing, carrying floor joists and often a chimney breast above. Before any demolition, our structural engineer calculates the load and specifies an RSJ, its bearing length and the padstones it lands on. We install temporary props, cut the opening in careful stages and never disturb the structure until the steel is fully supported.
Padstones spread the concentrated load into the surrounding brickwork, which matters in these older SW2 properties where mortar can be soft and walls solid rather than cavity. Once the beam is seated and levelled, we build it in, protect it for fire resistance where required and arrange the building control inspection. Every stage is documented so the completed structural opening passes without fuss and leaves you with proper paperwork.
Many Brixton terraces share their side wall or a chimney breast with the house next door, so cutting a beam pocket into that shared wall brings the Party Wall Act into play. Where the steel bears on a party wall, you must serve notice on your neighbour before work starts. We flag this early, explain the notice period and coordinate with your party wall surveyor so nothing stalls the build.
Removing a chimney breast on a Brixton terrace is a common request, but the stack above still needs support. We install gallows brackets or a beam so the remaining brickwork stays safe, again with engineer's calculations and building control sign-off. Working in occupied SW2 homes, we prop and protect as we go, keep dust down with sheeting and clear the site each day so you can live around the works.
Brixton homeowners choose GS Renovation for steel work because we handle the whole chain, the engineer's design, the propping, the demolition and the building control inspection, as one accountable team. With 30+ years across Lambeth, we know how these solid-walled SW2 terraces behave, we serve party wall notices correctly and we leave every opening safe, level and signed off.
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 Brixton 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.
How long RSJ and steel beam installation takes in Brixton depends on the size of the job, but we always agree a programme before starting and stick to it, keeping you informed from the first day to the last.

Removing a load-bearing wall in Brixton 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 Brixton's homes are Victorian and Edwardian terraced properties, and we renovate them regularly. We plan each RSJ and steel beam installation around their particular characteristics, such as solid brick walls, rear closet wings, side returns and original period features, so the result suits the building and meets building control.
Often, yes. If the steel bears on the wall you share with a neighbour, or you cut into a shared chimney breast, the Party Wall Act applies and you must serve notice before work begins. We identify this at survey stage, help you issue the correct notices and coordinate with the surveyor so your beam installation stays on schedule.
We do. GS Renovation covers all of Brixton and the SW2 area and the wider South London. Call 07472 424 226 and we will confirm we work on your road.
