Steel beam installation, rsj and structural alterations in Kensington. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs steel beams and RSJs across Kensington, from the white-stucco townhouses of W8 to the period mansion flats near Holland Park. With over 30 years of structural experience in the Royal Borough of Kensington and Chelsea, we open up load-bearing walls in Georgian and Regency homes, working to a structural engineer's design and building control sign-off.

Removing a load-bearing wall in a Georgian or Regency townhouse in W8 begins with a structural engineer sizing the RSJ for the loads above, which in a tall Kensington house can mean several storeys of masonry and a chimney stack. We install temporary propping, carry out staged demolition safely, and set the beam onto padstones that spread the load into the existing walls without overstressing them.
Many Kensington homes are terraced, so the dividing wall between you and your neighbour is a shared party wall under the Party Wall Act. Where a beam bears into that wall, we help you serve the correct notices before work starts. Every stage, from the padstone bearings to the finished beam, is inspected and signed off by building control in the Royal Borough of Kensington and Chelsea.
A large share of Kensington's Georgian and Regency stock is listed or sits within a conservation area, which changes how structural work is planned. The steelwork itself is governed by building regulations rather than planning, but where a listed interior is affected, listed building consent from the council may also be required. We coordinate the engineer, building control and any consents so nothing is missed on your project.
Kensington's period houses often hide surprises behind the plaster, such as timber lintels, earlier alterations or walls that grow thicker at lower levels. We survey before we prop, so the temporary support and the RSJ suit the real construction rather than an assumption. Whether you are opening a rear reception near Holland Park or a lower-ground kitchen off the King's Road, we keep the structure safe throughout the works.
Kensington homeowners choose GS Renovation because we treat structural work in listed and period homes with the care it demands. One team manages the engineer's design, the propping, the party wall notices and building control, so a load-bearing change in your W8 townhouse is handled safely and properly signed off, backed by more than 30 years in 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
Pricing RSJ and steel beam installation in Kensington comes down to the size of the job, the specification you choose and the condition of the property. Rather than guess, we survey and give you a fixed, itemised quote you can rely on. Call 07472 424 226. 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.

Removing a load-bearing wall in 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 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.
Usually yes. Kensington townhouses share party walls with their neighbours, so if the new steel beam bears into that shared wall, or you cut into it, the Party Wall Act applies and you must serve notice first. We help you identify the affected neighbours and time the notices correctly, then coordinate the structural engineer and building control so the installation stays fully compliant.
