Steel beam installation, RSJ and structural alterations in Richmond upon Thames. Trusted, professional, 30+ years' hands-on experience.
Removing a load-bearing wall in a Richmond upon Thames period home calls for precise structural work. GS Renovation installs RSJs and steel beams across TW9, TW10 and the wider borough, from Georgian townhouses near Richmond Park to Victorian homes in Kew. With over 30 years of experience, we prop and fit every beam to the engineer's sizing to building control standards.

Richmond's Georgian and Regency townhouses were built with solid masonry walls that carry real load, so removing one to open up a room is never a simple knock-through. Our structural engineer calculates the beam size from the loads above, whether that is a floor, a chimney stack or the roof. The RSJ then bears onto concrete or engineered padstones at each end, spreading the weight safely into the remaining walls.
Before any demolition, we install temporary props such as Acrows and strongboys to hold the structure while the wall comes down in controlled stages. This staged approach protects the original cornicing, plaster and floors that Richmond homeowners want to keep. Once the steel is seated and packed tight, we remove the props, fireproof the beam and arrange the building control inspection that signs off the finished structural opening.
Many Richmond upon Thames houses share a party wall with the neighbour, and chimney breasts and dividing walls often sit within it. If your beam bears into that shared wall, the Party Wall Act applies and formal notice must be served on the adjoining owner before work begins. We help you plan the notice period into the programme so the structural stage is not delayed by paperwork or a neighbour dispute.
In TW1, TW2 and TW11, where Teddington and Twickenham terraces sit tightly together, we coordinate the propping and cutting to avoid disturbance to the party wall. Building control, not planning permission, governs the structural side of a beam installation, so the sign-off confirms the opening is safe and compliant. Where the property is listed or in a conservation area, we flag any consent needed before touching the fabric.
Homeowners across Richmond upon Thames trust GS Renovation because we treat steel beam work as a controlled engineering job, not a rushed knock-through. Our engineer sizes every RSJ, we prop safely, serve any see the building control sign-off through. With 30+ years in TW9, TW10 and beyond, you get one accountable team from calculation to finish.

FAQ
No, because everything foreseeable is on the quotation already. RSJ and steel beam installation in period, Georgian and listed housing around TW1 occasionally reveals something behind plaster, and when it does we stop, cost it, and get your agreement before continuing at the Richmond upon Thames property. GS Renovation carries the same approach across Richmond upon Thames. Quotes are free and carry no obligation, whether the TW1 property sits in Richmond upon Thames or the wider South West London, and the written figure follows within days. 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.
Usually, and consent comes before the structural design is finalised. Where your Richmond house carries statutory protection, consent is required for alterations affecting its character, and that can extend to internal walls and the plan form. The structural solution may also have to change to preserve what is protected. We establish which consents apply before the engineer is asked for a final design.
By arranging the delivery before the steel is fabricated. Several streets around Richmond are narrow, busy or subject to parking controls, so a long section cannot simply be unloaded at the door. A bay is suspended where one is available, deliveries are timed away from the busiest hours, and where the frontage will not take it the engineer specifies a beam that arrives in shorter lengths.
Either raised into the floor above or boxed to match the room's existing detail. In your Richmond house with cornice and tall ceilings, a plain boxed downstand can look like an intrusion. The beam is either kept within the floor depth at greater cost, or boxed with returns and a matching moulding so it reads as part of the room. That decision is made before the steel is ordered.
By building control for the regulations, and separately against any consent for the alterations. At a Richmond property that means the bearings, padstones and fire protection are seen before the beam is concealed, while the consent conditions govern what may be removed and how it is reinstated. The two are not interchangeable, and satisfying one does not discharge the other.
