Steel beam installation, RSJ and structural alterations in Hackney. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs RSJs and steel beams across Hackney, from the warehouse conversions near Shoreditch to the Victorian terraces around London Fields. With over 30 years of structural work in E2, E8, N1 and N16, we handle engineer-sized steel, safe propping and building control sign-off, whether your home is leasehold or freehold.

In Hackney's warehouse conversions across Shoreditch and Hoxton, many walls that look structural are load-bearing party elements shared with the flat next door. Before any steel goes in, we have a structural engineer size the RSJ, then agree the works with your freeholder and managing agent. Removing a load-bearing wall in a leasehold flat needs a licence to alter, so we prepare the drawings and calculations the building management will want to see before anything starts.
We prop the structure safely, take the wall down in controlled stages, and seat the new beam onto padstones sized to spread the load. Sound insulation matters between flats, so we detail the beam and any new floor build-up to meet building regulations for airborne noise. Hackney Council's building control team, or an approved inspector, signs off the completed steelwork before we close everything up and make good the surfaces around it.
Away from the conversions, Hackney still has streets of solid-wall Victorian terraces around Victoria Park and Stoke Newington. Here the wall between the front and rear reception, or the chimney breast, usually carries load from the floors and roof above. We remove it with a steel beam calculated by an engineer, propping the floors first and building in bearings that transfer weight cleanly down through the structure to the foundations below.
Because a terrace shares its flank walls with the houses either side, opening up near a party wall brings the Party Wall Act into play. you serve the correct notices on your neighbours in E5, E8 or E9 before work starts, keeping the process transparent. Once the beam is fitted and inspected by building control, we plaster and reinstate so the finished room shows no sign of the wall that stood there.
Hackney homeowners choose GS Renovation because structural work here is rarely simple, whether it is a leaseholder's licence to alter in a Dalston conversion or a party wall notice on a Victorian terrace. With 30+ years behind us, one accountable team manages the engineer, the steel, the propping and the building control sign-off, working tidily in your occupied home.

FAQ
Be careful, particularly if nobody has visited. Pricing RSJ and steel beam installation for a warehouse-conversion and new-build Hackney house without seeing it is how a low figure becomes a high one halfway through, and the extras land at E2 when you have no leverage left. GS Renovation surveys, itemises and holds the total. A second opinion costs nothing and carries no obligation anywhere in Hackney. Call 07472 424 226 and we will look at the E2 quotation with you. 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 is designed for a frame rather than for masonry walls. Many Hackney conversions are former industrial buildings with brick piers, iron columns or a concrete frame carrying the loads, so a new beam connects into that structure instead of bearing into a solid wall. The engineer establishes how the existing frame works before designing anything, because the load path in these buildings is rarely where an owner assumes it is.
Sometimes, and the fire requirement decides it. An exposed beam suits the character of a Hackney industrial conversion, but unprotected steel is vulnerable in a fire and the required protection is set by what the beam supports and whether it separates dwellings. Intumescent coating can achieve a protected finish while keeping the profile visible. That specification comes from the design and is agreed with building control.
The freeholder or management company, alongside building control. Most Hackney conversions are leasehold, and the lease reserves alteration of structure to the landlord, with the building's management company often administering it. Their surveyor generally reviews the engineer's calculations before a licence to alter is granted. That process runs in parallel with the building control application rather than after it.
Yes, and it is more demanding than in a house. Where your Hackney flat is a single open volume, there is no protected hallway between the living space and the front door, so detection, the fire performance of the entrance door and the escape route through the building all matter. The strategy is agreed with building control before walls come out rather than justified afterwards.
Often, provided the brick behind the plaster is sound enough to show. In your Hackney conversion the internal face is frequently common brick that was never meant to be seen, with old openings, patches and mortar of varying quality. Cleaning and repointing it is a considerable piece of work in itself. The engineer also confirms nothing structural depends on the plaster being there.
