Steel beam installation, rsj and structural alterations in Knightsbridge. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs RSJs and steel beams across Knightsbridge, where the SW7 housing stock runs to Georgian and Regency townhouses, many listed or sitting within a conservation area. With over 30 years of structural work in the Royal Borough of Kensington and Chelsea, we open up these period homes safely and to building control standards.

The internal walls of a Knightsbridge townhouse were built to carry real load, from lath-and-plaster partitions to solid masonry spines running the depth of the plot. Before any wall comes down, a structural engineer sizes the RSJ or steel beam for the span and the floors above, and specifies padstones to spread the bearing into sound brickwork. Nothing is removed until the calculations are agreed and the building control application is in place.
On site we install temporary propping to take the load, then carry out safe, staged demolition rather than knocking a wall through in one go. The beam is lifted in, seated onto its padstones and packed tight, and the propping stays until everything is bearing correctly. In these tall Georgian and Regency houses we plan lifting and access carefully, protecting original features and the fabric of a listed or conservation-area property throughout.
Knightsbridge townhouses sit in terraces and stucco-fronted rows, so the chimney breasts, spine walls and dividing walls you want to alter are frequently shared with the house next door. Where a beam bears into a party wall, or work affects a structure on the boundary, the Party Wall Act applies and notices must be served on the adjoining owner before we begin. We flag this early so timescales are realistic.
We coordinate the party wall process alongside the structural design, so the engineer's drawings, the notices and the building control sign-off all line up. In a densely built SW7 street, keeping neighbours informed and the paperwork correct avoids disputes and keeps the project moving. Once the steel is in, inspected and signed off by building control, we make good the openings and hand back a room that feels open yet remains structurally sound.
Homeowners in Knightsbridge choose GS Renovation because we treat structural steel in a listed or period townhouse with the care it demands. Engineer-sized beams, correct padstones, staged demolition, party wall notices and building control sign-off are all handled by one accountable team with 30+ years across the Royal Borough.
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
The cost of RSJ and steel beam installation in Knightsbridge depends on the size of the property, the specification and the scope of work. GS Renovation provides free, detailed and itemised quotations for every Knightsbridge project. Call 07472 424 226 or email info@gsrenovationltd.co.uk for a no-obligation estimate. 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 Knightsbridge 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 Knightsbridge 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 Knightsbridge'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.
Usually yes. Most Knightsbridge townhouses share a party wall with the neighbouring property, and if the new steel beam bears into that shared wall the Party Wall Act applies, so notice must be served before work starts. We arrange the structural design, the notices and the building control sign-off together, and advise you on the required timescales at the outset.
Absolutely. Our team works right across Knightsbridge and the SW7 area and neighbouring parts of Central London. Get in touch on 07472 424 226 to check coverage for your address.
