Steel beam installation, rsj and structural alterations in South Kensington. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs RSJs and structural steel beams across South Kensington, working with the grand period houses of the museum quarter. With over 30 years of experience in SW7, we remove load-bearing walls in Georgian and Regency townhouses safely, sizing every beam by a structural engineer and clearing each stage with building control.

The tall, thick-walled townhouses of South Kensington were built as a run of rooms, and opening them up to modern living almost always means taking out masonry that carries the floors above. In SW7 those loads are considerable, so a structural engineer calculates the beam and specifies padstones to spread the bearing into the solid brickwork rather than crushing it.
We prop the structure temporarily, cut out the wall in controlled stages, and lift the RSJ into position before easing the load onto it. In a four or five storey Georgian house the sequencing matters enormously, and our teams have done this repeatedly across the Royal Borough of Kensington and Chelsea without disturbing the floors overhead.
So many South Kensington houses share a party wall with the neighbour, and chimney breasts and dividing walls frequently sit on that shared line. When a beam bears into or near a party wall, the Party Wall etc. Act 1996 applies, which means serving notice on the adjoining owner before work begins. We flag this early so the legal side and the build stay on the same timeline.
Because much of SW7 sits within conservation areas and a good number of houses are listed, we keep structural change internal and reversible wherever we can. Building control inspects the beam, the bearings and the fire protection, and issues the completion certificate that protects the value of a period home when it is later sold or let.
South Kensington homeowners choose GS Renovation because we treat structural work in a period house with the care it demands. One accountable team handles the engineer's steel, the propping, the party wall notices and building control sign-off, working cleanly in an occupied home. Over 30 years across the Royal Borough of Kensington and Chelsea stands behind every beam we set.
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 South Kensington 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.
Timescales for RSJ and steel beam installation in South Kensington vary with the size and complexity of the job. After our survey we give you a realistic schedule and keep you updated at every stage of the project.
South Kensington homeowners choose GS Renovation for reliability and quality. We are fully insured, building control compliant where needed, and bring over 30 years of hands-on experience to every RSJ and steel beam installation project, with a single point of contact throughout.
Removing a load-bearing wall in South Kensington 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 South Kensington's homes are period, Georgian and listed properties, and we renovate them regularly. We plan each RSJ and steel beam installation around their particular characteristics, such as conservation and listed-building rules, solid walls and original period features, so the result suits the building and meets building control.
Removing an internal load-bearing wall is a building regulations matter, not planning, so it needs a structural engineer's design and building control sign-off rather than a planning application. If the wall is shared, a party wall notice is also required. Planning only enters the picture if your SW7 house is listed or the change affects the exterior within the conservation area.
We cover the whole of South Kensington and the SW7 area and the surrounding Central London. If you are nearby and not sure, just call 07472 424 226 and we will tell you straight away.
