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, 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.
Steel installation is the loudest week of any project and there is no way to make it quiet, so the honest approach is to compress it. In a Kensington house we get the propping up, the slot cut and the beam in as one continuous run rather than spreading it across a fortnight, which limits the days of breaker noise to two or three and gets the room back into use sooner.
Around that, ordinary life carries on. We seal the working room, run extraction while cutting and keep a clean protected route from the front door to it. Services in the wall are traced and moved first so there are no unplanned losses of water or power. In a mansion flat we agree the noisy days with the managing agent and warn the flats above and below, since impact noise travels through a floor to every home on the stair.
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 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.

FAQ
The totals are usually closer than the structures behind them. A national firm subcontracts the RSJ and steel beam installation work in Kensington and prices its own overhead into your quotation, whereas GS Renovation carries out the W8 job with its own team. That also means one named project manager rather than a call centre. Ask both quotations for the same itemised breakdown. Ring 07472 424 226 and GS Renovation will explain who would actually be on your W8 site in Kensington. 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.
Usually something that could have been foreseen at survey. In grand terraces and garden-square houses laid out over four and five storeys the classic hold-up on RSJ and steel beam installation is discovering the structure at a W8 property is not what the drawings suggested, which is why GS Renovation investigates before committing to a Kensington programme. Beyond that it is inspection slots and deliveries. Both are booked ahead across Kensington and Chelsea. GS Renovation investigates the structure at the W8 property before any Kensington date is committed to paper.
Yes, for practical reasons rather than sentimental ones. A contractor that works across Kensington and Chelsea knows the Royal Borough of Kensington and Chelsea building control process, the parking constraints at W8 and the way local houses were built, all of which affect an RSJ and steel beam installation job. GS Renovation has covered this area for years. Ask any firm for addresses of finished Kensington and Chelsea work. Email info@gsrenovationltd.co.uk for a free survey. Ask what happened when something went wrong on a previous job.
A structural engineer, always. GS Renovation is a contractor: we appoint and coordinate the engineer, then build to their specification. The calculations size the beam, the padstones and the bearings for your W8 opening, and Royal Borough of Kensington and Chelsea inspects against that design.
Yes, extensively. GS Renovation works on that stock throughout Kensington and Chelsea and Kensington, so RSJ and steel beam installation at a W8 address draws on repeated experience rather than a first attempt. Our founder has over 30 years of hands-on experience behind those judgements. Ask for references and we will give you addresses of finished work near Chelsea. Email info@gsrenovationltd.co.uk and we will describe recent RSJ and steel beam installation projects of that type across Kensington and Chelsea and in Kensington itself.
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.
