Steel beam installation, rsj and structural alterations in Kilburn. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs RSJs and steel beams across Kilburn, from the red-brick mansion blocks off the NW6 high road to the Victorian terraces that run back towards Queen's Park. With over 30 years of structural work behind us, we size, prop and place steel to open up mansion-flat and period-flat interiors safely.

Most of Kilburn's homes are leasehold, so a steel beam in a mansion block or purpose-built period flat starts with your freeholder's licence to alter, not just the drawings. We work with the managing agent, share the structural engineer's calculations and confirm the beam size, the padstone bearings and the propping method before anyone lifts a tool. Sound insulation between flats and the building's own rules shape how we sequence the job.
Because structural change is limited in a leasehold flat, we keep openings realistic and design the steel to suit what the freeholder will allow. In Kilburn's Victorian terraces the picture differs: dividing walls and chimney breasts often sit within a shared party wall, so the Party Wall Act applies and neighbours must be served notice. Either way, temporary propping goes in first, demolition is staged and cautious, and Brent Council building control signs off the finished beam.
Removing a load-bearing wall in an NW6 property is never a guess. A structural engineer inspects the wall, works out the loads it carries from the floors and roof above, and specifies the right RSJ and its bearings. In a mansion block those loads travel through several storeys, so the engineer checks that the columns and existing structure below can take the beam before we commit to an opening.
On site we prop the structure fully, take the wall down in careful stages and set the steel onto concrete padstones that spread the load into sound masonry. We manage the dust and noise that flats demand, protect shared hallways and communal areas, and keep the managing agent informed. Once the beam is in and packed tight, building control inspects it, and we make good the ceilings, walls and finishes around the new opening.
Kilburn homeowners choose GS Renovation because we understand both sides of NW6: the leasehold reality of the mansion blocks and the party wall duties of the Victorian terraces. One team handles the engineer's calculations, the freeholder's licence, the propping and the building control sign-off, with 30+ years of steel and structural work across Brent behind every job.
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 Kilburn 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.
Timescales for RSJ and steel beam installation in Kilburn vary with the size and complexity of the job. After our survey we give you a realistic schedule and keep you updated at every stage of the project.
GS Renovation knows Kilburn's homes and how to renovate them properly. We handle the structure, the services and the finishes, deal with building control for you, and leave you with work that is certified, guaranteed and built to last.
Removing a load-bearing wall in Kilburn 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 Kilburn's homes are mansion-block and period-flat properties, and we renovate them regularly. We plan each RSJ and steel beam installation around their particular characteristics, such as leasehold consents, shared structure and sound insulation between flats, so the result suits the building and meets building control.
You need two things. First, because the flat is leasehold, your freeholder's written licence to alter, arranged through the managing agent. Second, building regulations approval, since a steel beam is structural work signed off by Brent Council building control. You do not normally need planning permission for internal work, but the freeholder's consent and the engineer's calculations are essential.
We do. GS Renovation covers all of Kilburn and the NW6 area and the wider North West London. Call 07472 424 226 and we will confirm we work on your road.
