Steel beam installation, RSJ and structural alterations in Stratford. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs RSJs and steel beams across Stratford, from the warehouse conversions and new-build riverside apartments near the Queen Elizabeth Olympic Park to the Victorian terraces of E15. With over 30 years of structural experience in Newham, we open up load-bearing walls safely and sign every beam off with building control.

A load-bearing wall removal in a Stratford home starts with a structural engineer sizing the RSJ for the span and the load above. In the Victorian terraces around West Ham Park the dividing wall is usually solid brick, so we install temporary propping, take the wall down in stages and lower the beam onto padstones at each bearing. Every step is planned before the props go anywhere near the ceiling.
In a warehouse conversion or new-build apartment near the Royal Docks the picture is different. Structural change is limited by the building's frame, so we work with your engineer and your freeholder to confirm what can move. The leasehold almost always requires the freeholder's licence to alter, and the managing agent will want method statements before any steel is ordered or a single wall comes down.
Many Stratford terraces share a party wall with the neighbouring house, and in an apartment block you may share structure with the flat next door or below. Where a beam bears into a shared wall, the Party Wall Act applies and notice must be served on the affected owners before work begins. We flag this early so the notice period runs while the engineer's drawings and the building control application are being prepared.
Building control sign-off is separate from planning permission and is what matters for steel. An inspector checks the beam size, the padstones, the bearing and the fire protection against the approved drawings. We book the inspections, keep the calculations on site and arrange the final certificate once the work passes. For leaseholders in E15 we also hand the paperwork to the managing agent, who often needs it for the building's records.
Removing a wall in one of the newer blocks near the Olympic Park is a different exercise from opening a Victorian terrace. Many internal walls in a concrete-framed building are metal stud partitions carrying nothing, so no beam is needed at all; the structure is in the frame and the slabs. What matters instead is establishing which walls are structural and what is buried in the slab before anything is cut.
That last point is important. Some modern slabs are post-tensioned, with tendons running through them that must never be drilled or cored without the original structural information and a scan. Fixings into the soffit, new drainage through a floor and any core hole all need checking first. The lease will also require the freeholder's consent and a structural engineer's report before work starts. We obtain the building's structural drawings where they exist rather than assuming the wall is only plasterboard.
Homeowners in Stratford choose GS Renovation because we treat structural work as the serious job it is. One team handles the engineer's drawings, the propping, the beam and the building control sign-off, whether your home is a Victorian terrace or a leasehold apartment. Thirty years in Newham means we know the local stock and the paperwork inside out.

FAQ
Check what has been left out before deciding. Cheap RSJ and steel beam installation quotations in Stratford tend to be rather light on approvals and reinstatement, and work started without Newham Council sign-off becomes expensive when the E15 property is sold. GS Renovation includes both as standard. We would rather lose the job than win it by omission. Ring 07472 424 226 and GS Renovation will explain what a complete Newham quotation should contain, and what it should not. 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.
We tell you early rather than at the end. Most overruns on an RSJ and steel beam installation job in a Stratford home come from something found once the E15 property is opened, and that is costed and agreed in writing before we carry on. GS Renovation does not use delay as a reason to add to the price. The Newham programme is reissued so you can plan. Nothing is added to a Stratford account at E15 because a Newham programme slipped.
We are a contractor, not a middleman. The RSJ and steel beam installation work at your E15 property is carried out by our own team rather than brokered to whoever is cheapest that week, which is why one person can be accountable for the whole Stratford job. GS Renovation is fully insured, company number 14611254. The engineer, where the design needs one, is appointed by us. Ring 07472 424 226 for Newham references. The certificate is available at the E15 survey in Newham.
Almost any wall can be opened up, but what the beam has to carry and what it bears onto change completely. In a Stratford property the load path matters more than the wall itself, which is why an engineer assesses the E15 address before we quote.
Sometimes, depending on where the property sits. RSJ and steel beam installation in modern apartment blocks with concrete frames and shared service risers within a conservation area is usually possible but more constrained in form, and Newham Council will scrutinise anything visible from the street at E15. GS Renovation handles the application and the negotiation. Internal work in a Stratford house is generally more straightforward. Ring 07472 424 226 and we will explain what Newham Council is likely to ask about RSJ and steel beam installation at an E15 address of that age.
You do not need planning permission for internal structural work, but you do need building control approval, and the steel must be sized by a structural engineer. In a leasehold apartment near the Olympic Park you will also need the freeholder's licence to alter and the managing agent's agreement, since the building's frame and sound insulation between flats are shared. We handle all of it.
Yes, boundaries are not something we price against. RSJ and steel beam installation runs across Newham and into East London, so an address on the edge of Stratford or over towards East Ham is no harder to service. GS Renovation will say plainly if travel makes it impractical. Ring 07472 424 226 with the E15 postcode and we will confirm. The survey that follows is free and carries no obligation. Aftercare is no more difficult a few streets further out.
