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 you 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 and making good as one accountable team, tidily and on time.

FAQ
It moves, and you see the movement immediately. Because the RSJ and steel beam installation quotation for a Highgate home is itemised, a change to the specification at N6 is priced against the same lines rather than renegotiated wholesale. GS Renovation issues a written variation and waits for your approval. That protects both sides on every Camden project. Ring 07472 424 226 and GS Renovation will explain how a variation at your N6 address in Highgate is agreed. 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.
The whole sequence is set out for you at the start. Survey, quotation, engineer where RSJ and steel beam installation needs one, Camden Council approval, then construction at the N6 property, each with an indicative duration. GS Renovation updates a Highgate client weekly once work begins. That way nobody in the Camden household is guessing when the house comes back. Ring 07472 424 226 and GS Renovation will set out the whole sequence for an N6 home in Highgate.
A five year guarantee applies to installations, and it is backed by a real company. We are GS Renovation Ltd, number 14611254, fully insured, which a Highgate homeowner can verify before RSJ and steel beam installation begins at N6. The Camden Council certificate covers the regulated element. GS Renovation would rather you checked all of it than took our word. Email info@gsrenovationltd.co.uk and we will send the Camden paperwork. Verification takes a Highgate homeowner about a minute.
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 N6 opening, and Camden Council inspects against that design.
Always. Applying a standard detail to Edwardian bay-fronted houses with generous ceiling heights and long rear gardens is how original features get damaged, so GS Renovation plans RSJ and steel beam installation around what the N6 property actually is. The engineer's design covers the structure; the finishing is matched to what is already in the Highgate house. You agree both before work begins in Camden. Ring 07472 424 226 and we will explain how RSJ and steel beam installation is matched to the finishes already present in an N6 home today.
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. 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.
Never for a Highgate address. Charging for travel would make the RSJ and steel beam installation figure depend on where our van started rather than on your N6 property, which is not how GS Renovation prices anything. Distance only matters well beyond Camden Town, and we would say so upfront. Call 07472 424 226 for a no-obligation quotation. The survey across Camden is free in every case. Two similar homes across Camden would receive comparable figures either way.
