GS Renovation installs steel beams and RSJs across London, from the bay-fronted Victorian terraces of Wandsworth and Hackney to the taller Edwardian homes of Islington and Camden. With more than 30 years of structural experience across Greater London, we remove load-bearing walls safely, working to a structural engineer's design and building control sign-off.
Steel beam knock-throughs in London terraces
The most common structural job in London's Victorian and Edwardian terraces is opening up the ground floor, either taking down the wall between the two reception rooms or removing the back wall of the rear closet wing. Because these walls carry the floors and often a chimney stack above, we install an RSJ sized by a structural engineer, propping the structure temporarily before any masonry comes down and bearing the new beam onto concrete padstones.
Safe sequencing matters most in an occupied London home. We plan the demolition in stages, protect the surrounding plaster and floors, and keep the props in place until the steel is fully seated and the load transferred. Every beam we fit is inspected and signed off by building control at the relevant London local authority, so you have the documentation you need for warranties, insurance and any future sale of the property. Nothing is guessed and nothing is hidden behind the plaster.
Party wall notices across London boroughs
In London's terraced streets, the dividing wall between you and your neighbour is usually a shared party wall, and the chimney breasts sit within it. Where our steelwork bears into that wall, the Party Wall etc. Act 1996 applies, and you must serve notice on the adjoining owners before work starts. We help you understand which notices are needed, whether that is a line of junction notice or a party structure notice, and the timescales involved.
Getting the party wall process right protects everyone. A surveyor records the condition of the neighbouring property before we begin, which avoids disputes later if a crack appears in shared plaster. Across boroughs like Camden, Islington and Wandsworth, where terraces are packed tightly together, this step is not optional paperwork, it is what keeps the job legal and the relationship with your neighbour intact. We coordinate the structural design and the notices so the two run in step.
