Steel beam installation, RSJ and structural alterations in Shepherd's Bush. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs RSJs and steel beams across Shepherd's Bush, where W12 is dominated by bay-fronted Victorian and Edwardian terraces with rear closet wings and side returns. With over 30 years of structural work in Hammersmith and Fulham, we remove load-bearing walls safely, from homes near Westfield London to the streets running down towards the River Thames.

The dividing wall between the front and rear reception rooms in a W12 terrace is almost always load-bearing, carrying floor joists and often a chimney breast above. Before any demolition, we have a structural engineer calculate and specify the correct steel, whether that is a single RSJ or a goalpost frame. We then set up temporary propping, take the wall down in careful stages and lower the beam into position without disturbing the floors overhead.
Each end of the beam has to bear onto a properly sized padstone, spreading the load into the solid brickwork these terraces are built from. Because the front-to-back wall in a Shepherd's Bush terrace frequently sits on the boundary with next door, the work often falls under the Party Wall Act, so notices must be served on neighbours first. Once the steel is in, building control inspects the installation and issues the completion certificate you will need.
Homeowners in Shepherd's Bush often want a chimney breast taken out to reclaim space in a narrow bedroom or reception. Removing the breast on the ground and first floors leaves the stack above needing support, which we provide with a gallows bracket or, more commonly on party walls, a steel beam. Where the chimney is built into the shared wall with the adjoining house, the Party Wall Act applies and the neighbour's stack must stay properly supported throughout.
We also handle the larger structural openings that come with side-return and rear extensions, where several beams may connect to form a frame supporting the existing rear wall and the new roof. Every steel is sized to the engineer's drawings, seated on padstones and signed off by Hammersmith and Fulham building control. Throughout the job we keep your home weathertight and clean, propping and sequencing the work so that the property stays safe and stable at every stage.
Shepherd's Bush homeowners choose GS Renovation because we treat structural work as our core trade, not a sideline. Over 30 years in Hammersmith and Fulham has taught us how W12 terraces are built, how their party walls behave and how to satisfy building control first time. One team manages the engineer, the propping, the steel and the neighbour notices, so the job is safe, compliant and finished cleanly.

FAQ
Rates per square metre are how quotations go wrong. What decides an RSJ and steel beam installation figure for a Shepherd's Bush home is the structure, the access at W12 and the reinstatement afterwards, none of which appear in a market average. GS Renovation itemises so the total can be traced back to real work. Homeowners across Hammersmith and Fulham are welcome to a free survey first. Ring 07472 424 226 and GS Renovation will explain what your W12 property actually needs. 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.
Yes, because the loads and the fire requirements are both different. A converted Shepherds Bush terrace carries floor loads from separate households and the floors are doing fire separation work as well as structural work. The engineer designs for the loads actually present rather than a single dwelling, and the encasement to the new steel is agreed so the compartment is reinstated when the beam is boxed in.
It gets assessed before anything is added to it. Earlier work in Shepherds Bush terraces was often carried out without records, and undersized beams, bearings that are too short and openings with no beam at all are all found. The engineer inspects what is there, and where the existing work is inadequate the options are replacing it or regularising it with building control. Building on top of it is not one of them.
With the loading arranged in advance rather than on the day. Frontages on the busier Shepherds Bush roads have restricted waiting and heavy passing traffic, so a beam is delivered into a suspended bay or at an agreed quiet hour. Where the frontage cannot take it, the engineer is asked for a spliced design that arrives in sections short enough to carry through the house.
The finish is matched to what is already there, which in older Shepherds Bush houses often means lath and plaster. New plasterboard butted against old lath moves differently and cracks along the joint, so we cut the junction back to a sound line, scrim it and skim across. Where cornice runs into your new opening it is returned properly or stopped at a deliberate point rather than left ragged.
