Steel beam installation, rsj and structural alterations in Hampstead. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs RSJs and steel beams across Hampstead, from period cottages near the Heath to the substantial Victorian villas of NW3. With over 30 years removing load-bearing walls in bay-fronted terraces, we manage the engineering, the propping and the building control sign-off so your knock-through is safe, level and properly certified.

Most steel work in Hampstead involves opening up the rear closet wing or taking out the wall between the two reception rooms of a Victorian terrace. Because those walls carry the floors and often a chimney stack above, a structural engineer sizes the beam to the actual loads. We bear each end onto a concrete padstone, calculating the spread so the masonry below the bearing is not overstressed once the wall comes out.
Before any brick is touched we install temporary props and needles to hold the structure, then remove the wall in careful stages. On the tighter plots common near the village, access is limited, so we plan how the steel is craned or carried in, protect the period floors and staircase, and keep the site clean while the building is still lived in throughout the works.
The dividing walls and chimney breasts in a Hampstead terrace usually sit within a shared party wall, so cutting a beam bearing into that wall triggers the Party Wall Act. We help you serve the correct notice on the neighbouring owner in good time, and where a surveyor and schedule of condition are needed we point you to the right process before work starts, avoiding the disputes that hold up so many NW3 projects.
Every beam we fit is inspected and signed off under building regulations by Camden Council building control or an approved inspector, not planning permission, since removing an internal wall is a structural matter rather than a planning one. You receive the engineer's calculations, the padstone details and the completion certificate, which protects the value of the property and reassures any future buyer or surveyor across the borough.
Homeowners across Hampstead choose GS Renovation because one team handles the engineer's design, the propping, the party wall notices and the building control sign-off on your steel. With 30+ years in NW3 terraces and villas, we understand how these period structures carry load and how to open them up safely without cracking the plaster next door.
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 Hampstead 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.

Removing a load-bearing wall in Hampstead 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 Hampstead'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.
Almost certainly yes. In a Victorian terrace off the Heath the dividing wall is shared with your neighbour, and cutting a beam bearing into it falls under the Party Wall Act. You serve notice on the adjoining owner before work begins. We size the beam, arrange building control sign-off and guide you through the party wall steps so nothing stalls.
Yes, Hampstead is one of our core areas. We work on every street and the NW3 area and across the wider North London, so wherever your home is, call 07472 424 226 and we will confirm we can help.
