Steel beam installation, RSJ and structural alterations in Kentish Town. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs steel beams and RSJs across Kentish Town, working daily in the bay-fronted Victorian and Edwardian terraces that line the NW5 streets between Camden Town and Highgate. With over 30 years of structural experience, we remove load-bearing walls safely, from ground-floor knock-throughs to loft conversions, all sized, propped and signed off correctly.

The typical Kentish Town job opens up a solid-brick Victorian terrace, taking down the wall between the front and rear reception rooms or removing the closet-wing wall to widen the kitchen. Because these walls carry the floor and often the chimney breast above, a structural engineer sizes the RSJ first. We then set out temporary propping, cut carefully and lower the steel onto padstones so the load transfers cleanly to the existing brickwork.
Solid nine-inch walls in NW5 homes behave differently to modern cavity construction, so we never guess at bearings. Every beam sits on a properly calculated padstone, the propping stays in place until the steel is loaded, and demolition happens in staged sections rather than all at once. This keeps the floors above stable and protects the original cornicing and plaster that Kentish Town owners want to keep.
Most Kentish Town terraces share a party wall with the neighbours on both sides, and chimney stacks and dividing walls frequently sit within that shared structure. When a beam bearing lands in or on a party wall, the Party Wall Act applies. We flag this early, help you serve the correct notices on adjoining owners, and coordinate the timing so the steelwork proceeds without disputes or delays with the houses either side.
Building control is the other non-negotiable. Structural beam installation is governed by Building Regulations rather than planning permission, so Camden Council building control, or an approved inspector, checks the engineer's calculations and inspects the padstones and bearings before the opening is closed up. We arrange those inspections, keep the sign-off paperwork in order and hand you a completion certificate you can produce whenever you sell the house.
Four parties are usually involved and it helps to know which is which. The structural engineer is appointed to survey, calculate and design the beam, and we never produce those calculations ourselves. Building control, either the council or an approved inspector, checks that what gets built matches that design. A party wall surveyor comes in where notice is dissented or the work is complicated enough to want one.
We are the contractor. That means we appoint and coordinate the engineer, serve the notices, book the inspections, carry out the propping, the demolition, the steelwork and the making good, then hand you the certificates at the end. Owners in NW5 sometimes ring three separate firms for those roles and end up managing the gaps between them. One point of responsibility is simpler, and nobody is left waiting on somebody else's drawing. It also means one firm answers for the finished work rather than three pointing at each other.
Kentish Town homeowners choose GS Renovation because we handle the whole beam job under one roof, from engineer's calculations to propping, steel and building control sign-off. Thirty years working NW5 terraces means we know how these solid-wall houses are built, we work tidily in occupied homes, and we leave the structure certified and safe.

FAQ
Ask three builders in Camden and you will get three different numbers for RSJ and steel beam installation, usually because they have scoped three different jobs. We price the NW5 property after a survey and set out labour, materials, approvals and making good line by line. A Kentish Town homeowner can then see where any difference actually sits. GS Renovation puts all of it in writing. Ring 07472 424 226 and GS Renovation will arrange a free survey at your NW5 property. 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.
It depends on scope, and we will not pretend otherwise on the phone. Once the NW5 survey is done GS Renovation can give a Kentish Town homeowner real dates for RSJ and steel beam installation, including the Camden Council inspection points. Material lead times are ordered against that programme early. Ring 07472 424 226 and we will describe what a bay-fronted Victorian terraced property usually needs. Nothing about the Kentish Town dates is guessed once the free survey at NW5 is done.
You get the Camden Council completion certificate, the guarantee and a number that still answers. Installations carry a five year guarantee, and if something needs attention at your NW5 property after RSJ and steel beam installation is signed off you reach the same people who did the Kentish Town work. GS Renovation does not route aftercare through a call centre. Nothing about that is a brochure line. Ring 07472 424 226 whenever a Camden issue arises. The guarantee covers Camden installations for five years.
Almost any wall can be opened up, but what the beam has to carry and what it bears onto change completely. In a Kentish Town property the load path matters more than the wall itself, which is why an engineer assesses the NW5 address before we quote.
Yes, and the age of the building is rarely the deciding factor. What matters for RSJ and steel beam installation is what the NW5 structure is carrying and what Camden Council requires, both established before design. GS Renovation appoints the engineer where the work needs one. The Kentish Town survey is free and carries no obligation in Camden. Ask on 07472 424 226 exactly what RSJ and steel beam installation depends on at an NW5 address in Kentish Town before you decide anything at all.
Often yes. In NW5 terraces the dividing walls and chimney stacks usually sit within the shared party wall, so if your beam bearing lands in that wall the Party Wall Act applies and you must notify the neighbours. We identify this at survey stage, help you serve the correct notices, and time the steelwork so it runs smoothly with the houses on either side.
All of them, NW5 included, along with the neighbouring parts of Camden. GS Renovation does not price RSJ and steel beam installation differently by postcode, and there is no travel charge within Kentish Town and the NW5 area. Ring 07472 424 226 with your address and we will confirm immediately. The survey that follows is free and carries no obligation. Building control goes through Camden Council wherever the property sits. Small jobs and full projects are quoted on precisely the same written terms.
