Steel beam installation, rsj and structural alterations in Kensington and Chelsea. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs steel beams and RSJs across Kensington and Chelsea, from the stucco-fronted townhouses of Kensington and Chelsea to the mews homes off Holland Park. With 30+ years working in SW3, SW7, W8 and W11, we open up Georgian and Regency interiors safely, keeping the period fabric of these listed and conservation-area homes intact.

The Georgian and Regency townhouses across SW3, SW7 and W8 were built with solid masonry and load-bearing internal walls carrying the floors above. Removing one to create a wider reception or a through room means a steel beam sized by a structural engineer, bearing onto concrete padstones spread into the surviving brickwork. We prop the structure temporarily, take the wall down in careful stages and set the beam before any load returns onto it.
In these tall, narrow properties the loads are considerable, so beam sizing and bearing detail matter. We work to the engineer's calculations, confirm the padstone positions and arrange building control inspection at the key stages. Where a wall is shared with the neighbouring townhouse, the Party Wall Act applies and notices must be served before we cut into it, something we routinely handle for owners across the borough.
Most townhouses in Knightsbridge, South Kensington and Notting Hill sit in continuous terraces where the dividing wall and chimney stacks are genuine party walls shared with the adjoining owner. Cutting a beam pocket into that wall, or removing a chimney breast, triggers notice periods under the Party Wall Act. We flag this early so surveyors can be appointed and the schedule of condition agreed before the steelwork starts, avoiding disputes and delays.
Building control sign-off is separate from any party wall matter and separate again from planning. Internal beam installation is a building regulations job, inspected by building control, not a planning application to the Royal Borough of Kensington and Chelsea. Where the property is listed or in a conservation area, though, altering internal features can require listed building consent, so we check the property's status at the outset and advise accordingly.
Owners across Kensington and Chelsea choose GS Renovation because we treat steel installation in a period home as structural work, not a quick knock-through. We coordinate the engineer, padstones, propping, party wall notices and building control on listed and conservation-area properties, working cleanly in occupied homes. Thirty years in the borough means we understand SW3, W8 and W11 construction.
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
There is no fixed price for RSJ and steel beam installation in Kensington and Chelsea, because so much depends on your property and what you want to achieve. We survey first, then provide a transparent written quotation. Contact GS Renovation on 07472 424 226 for a free 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 Kensington and Chelsea 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 Kensington and Chelsea 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 Kensington and Chelsea'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. Chelsea townhouses in SW3 and SW10 sit in terraces where the dividing wall is a shared party wall, so cutting a beam pocket into it triggers the Party Wall Act. Notice must be served on the adjoining owner before work begins. We help arrange this alongside the engineer's design and building control inspection, keeping the whole process compliant and on schedule.
Yes, Kensington and Chelsea is one of our core areas. We work on every street and the SW3 area and across the wider Central London, so wherever your home is, call 07472 424 226 and we will confirm we can help.
