Steel beam installation, rsj and structural alterations in Hammersmith. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs RSJs and steel beams across Hammersmith, from the bay-fronted Victorian and Edwardian terraces near the River Thames to the period homes around W6. With more than 30 years of structural experience, we remove load-bearing walls safely, prop the floors above and open up these terraced houses without compromising the fabric of the building.

The typical W6 house is a bay-fronted Victorian or Edwardian terrace with a rear closet wing and a side return, and the walls between the front and middle reception rooms are usually load-bearing. Before any steel goes in, a structural engineer sizes the beam for the actual loads above, whether that is a single storey or the full stack of floors and roof carried by a slender terraced wall.
We install the RSJ onto engineered padstones that spread the load into the remaining masonry, then remove the temporary props once the beam is bearing correctly. Every stage is inspected by building control, from the propping and demolition through to the final steel and padstone detail, so the finished opening is signed off and safe for the life of the house.
Because Hammersmith terraces sit in continuous rows, the dividing wall between you and your neighbour is almost always a shared party wall, and the chimney breasts and stacks often sit within it. Cutting a beam pocket into that wall, or removing a chimney breast, brings the work under the Party Wall Act, so notices must be served on the adjoining owner before we start.
We help you serve the correct notices in good time and coordinate with any party wall surveyor appointed for the neighbouring property. On these older W6 walls we also allow for soft lime mortar, rubble-filled construction and hidden flues, which is why the engineer's design and our controlled, staged demolition matter so much on a terraced home.
Homeowners across Hammersmith choose GS Renovation because we handle the whole steel job as one accountable team, from the engineer's calculations and party wall notices to propping, demolition and building control sign-off. With 30+ years working on W6 terraces, we understand how these Victorian walls carry load and how to open them up cleanly and safely.
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
Every Hammersmith project is priced on its own merits, as the cost of RSJ and steel beam installation varies with the size, specification and condition of the home. We give a clear, itemised quote up front with no obligation. Call 07472 424 226 for an estimate tailored to your 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.
A straightforward Hammersmith project can be done in a couple of weeks, while a larger RSJ and steel beam installation with structural work runs longer. We set out a realistic, stage-by-stage programme before we begin so there are no surprises.

We offer free quotes, a dedicated project manager, full insurance, building control compliance where required, and comprehensive aftercare.
Removing a load-bearing wall in Hammersmith 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 Hammersmith'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.
In most W6 terraces, yes. The wall carrying the beam, or the one where you are removing a chimney breast, is usually the shared party wall with your neighbour, so the Party Wall Act applies and notices must be served before work starts. We arrange this alongside the engineer's design and building control, so nothing is missed and the opening is fully compliant.
Yes. We work throughout Hammersmith and the W6 area, as well as the surrounding parts of West London. Contact us on 07472 424 226 to confirm we cover your street.
