Steel beam installation, RSJ and structural alterations in Bow. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs RSJs and steel beams throughout Bow, working daily on the bay-fronted Victorian and Edwardian terraces that fill the E3 postcode. With more than 30 years of structural building behind us, we remove load-bearing walls safely, from ground-floor knock-throughs to chimney breast removals, all engineered and signed off correctly.

Most Bow homes are load-bearing masonry, so the wall between the front and middle reception, or the spine wall carrying the closet wing, cannot simply be knocked out. We start with a structural engineer who calculates the beam size, then order the RSJ and the padstones it will bear onto. Only once temporary propping is in place do we begin staged demolition, keeping the E3 property stable and the household safe throughout the works.
The rear closet wings and side returns common in Bow often hide beams already carrying floor and roof loads, so we survey carefully before touching anything. We install the new steel level and true, pack the bearings onto solid padstones, and knit the brickwork back in. Every beam we fit is inspected by building control under the Building Regulations, giving you a documented, signed-off structural alteration rather than an unverified opening.
Because Bow terraces are built in continuous rows, the dividing wall and the chimney stacks usually sit within a shared party wall with your neighbour. When a beam bears into that wall, the Party Wall etc. Act 1996 applies and formal notice must be served before work begins. We flag this early, explain the process in plain terms, and coordinate with your appointed surveyor so the legal side runs alongside the build rather than delaying it.
Serving notice properly protects you as much as your neighbour, recording the wall's condition before and after the steelwork goes in. For semi-detached and end-of-terrace properties near Bethnal Green and Whitechapel we handle the same requirements, whether the beam bears one end into a party wall or spans a full-width opening. We keep the paperwork tidy, so your Tower Hamlets project has a clean record from engineer's drawings through to building control completion.
Bow homeowners choose us because we own the whole structural job, from the engineer's calculations to propping, the RSJ itself and building control sign-off. Thirty years of removing walls in E3 terraces means we spot hidden loads early, prop safely and finish with a certified opening. One accountable team, tidy working and a straight answer at every stage.

FAQ
Any change is costed and agreed in writing before it is carried out. If you add to the RSJ and steel beam installation scope at your E3 property, or the late Victorian and Edwardian structure needs more than the survey suggested, GS Renovation sets out the effect on both price and programme. Work does not continue on a Bow site until you have agreed it. Ring 07472 424 226 and GS Renovation will explain how variations are handled at an E3 address. 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 replaces a wall that is carrying the floor above and often the roof. In the modest two storey terraces common in Bow the wall between the front and rear rooms usually supports the joists above. Removing it needs a beam sized for those loads, bearing into the flank walls at each end. The span is short, which keeps the section modest, and the bearings still have to be designed.
Usually, with the rear addition's own structure accounted for. In your Bow terrace the rear addition has its own roof and often a separate floor structure, and the wall joining it to the main house may carry both. The beam is designed for the combination, and where the addition's roof is being altered too, the two are designed together rather than in sequence.
Yes, and it is done before the beam goes in. Steel in your Bow property is primed or galvanised depending on where it sits, and a beam with a bearing in an external wall is more exposed to moisture than one in the middle of the house. The damp proof course is kept continuous at the bearing. Rust at a bearing pocket is slow, hidden and expensive to correct later.
It is useful information and not a substitute for design. A neighbour's Bow house may look identical and have a different floor span, an altered roof or a previous conversion behind the plaster. The engineer designs for the property being worked on. Where the neighbouring work was done without approval, it may also have loaded the shared wall in ways that affect the new bearing.
