Steel beam installation, rsj and structural alterations in Highgate. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs RSJs and steel beams across Highgate, where N6's bay-fronted Victorian and Edwardian terraces sit on the edge of Hampstead Heath. With more than 30 years of structural experience, we remove load-bearing walls safely, prop temporarily and open up period homes without disturbing the character these houses are known for.

Removing the wall between the front and rear reception rooms is the classic Highgate steel job. In a bay-fronted N6 terrace that dividing wall usually carries the floor above and often the chimney breast, so a structural engineer sizes the RSJ to suit the span and load before any demolition begins. We install padstones to spread the bearing into the solid brickwork, then take the wall down in careful, propped stages.
Temporary propping holds the structure while we lift the beam into place and build it in level. Because the dividing and chimney walls in these terraces frequently sit within a shared party wall, a party wall notice to the neighbour is usually needed, and we serve it in good time. Every beam is signed off by Camden building control, so your structural change is fully documented and compliant.
Highgate's Victorian and Edwardian houses were built with load-bearing masonry, so almost any wall you want to remove downstairs is doing structural work. Chimney breasts, spine walls and the wall to the rear closet wing all carry load, and taking them out without a properly sized beam risks cracking and movement. We start every project with an engineer's calculations rather than guesswork, which keeps your home safe and the works insurable.
Staged demolition matters just as much as the beam itself. We prop above and to the sides, cut pockets for the padstones, then remove the masonry in controlled sections so nothing is left unsupported. Dust protection and floor coverings keep the rest of your occupied N6 home clean while we work. Once the beam is bedded and the propping struck, Camden building control inspects before we plaster and make good.
Highgate homeowners trust us because we treat structural work as engineering, not guesswork. Every RSJ is sized by a qualified structural engineer, bedded on proper padstones and signed off by Camden building control. With 30+ years removing walls in N6 terraces, we handle propping, party wall notices and making good as one accountable team, tidily and on time.
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 Highgate, 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.
Most RSJ and steel beam installation projects in Highgate take between two and eight weeks depending on the scope and whether structural work is involved. We provide a clear programme before work begins so you know exactly what to expect.

Removing a load-bearing wall in Highgate 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 Highgate's homes are Victorian and Edwardian terraced properties, and we renovate them regularly. We plan each RSJ and steel beam installation around their particular characteristics, such as solid brick walls, rear closet wings, side returns and original period features, so the result suits the building and meets building control.
Usually yes. In Highgate's terraces the wall you are opening, or the chimney breast above it, often sits within the party wall shared with your neighbour, which brings the work under the Party Wall Act. We help you serve the correct notice in good time, and separately arrange the structural engineer's calculations and Camden building control sign-off for the beam itself.
Yes, Highgate is one of our core areas. We work on every street and the N6 area and across the wider North London, so wherever your home is, call 07472 424 226 and we will confirm we can help.
