Steel beam installation, RSJ and structural alterations in Paddington. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs steel beams across Paddington's Georgian and Regency townhouses, from the stucco terraces near Hyde Park to the listed homes throughout W2. With over 30 years of structural work in Westminster, we remove load-bearing walls, size and fit RSJs onto proper padstones, and keep every stage signed off by building control.

Paddington's period townhouses were built with solid masonry, and internal walls frequently carry floor and roof loads, so opening up a ground floor is rarely a simple demolition. A structural engineer sizes the steel beam or RSJ for the span, and we cast concrete or engineered padstones to spread the bearing into the solid walls. Temporary propping holds the structure while we take the old wall down in safe, controlled stages.
Because many W2 houses share a party wall with the neighbouring townhouse, and dividing walls and chimney stacks often sit within it, the Party Wall Act frequently applies. you serve the correct notices on adjoining owners in good time. Building control inspects the beam, its bearings and the propping before sign-off, and where the house is listed or in a Westminster conservation area we confirm what internal work needs consent.
The tall ceilings and generous reception rooms typical of Paddington's Regency and Victorian stock give room for deep beams, but the age of the fabric means every bearing point must be checked. We expose the wall head and confirm what sits above, whether that is a chimney breast, a masonry upper wall or timber joists, then match the padstone and beam to the real load path rather than an assumption.
On a knock-through between the front and rear receptions, or when forming an opening to a rear return, we manage the whole sequence, from propping and steelwork to making good the plaster, cornicing and flooring so the finished room reads as original. Fire protection to the steel, correct bearing lengths and a clean structural opening all form part of the building control sign-off we arrange on your behalf.
Paddington homeowners choose GS Renovation because structural work in listed and period W2 houses demands care, not shortcuts. One team handles the engineer's calculations, the propping and the building control sign-off, then makes good the period detail. With over 30 years in Westminster, we protect both the fabric of your home and your relationship with the neighbours.

FAQ
It covers the whole job through to sign-off. The document lists the structural work, the trades that follow, the Westminster City Council inspections and the making good at the W2 property, with the engineer's fee shown where RSJ and steel beam installation needs a design. Site protection and the daily clear-up are included. GS Renovation issues it in writing so a Paddington homeowner has something to hold us to. Ring 07472 424 226 for a sample Westminster layout before the W2 survey. 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 front elevation is rendered and unforgiving. The stucco fronted terraces around Paddington were built with soft mortar and lime render that shows movement as visible cracking, so the temporary works matter as much as the beam. Loads are taken on needles and props to the engineer's design before any masonry is cut, and the structure is watched while the beam is seated and pinned up.
Often, and that history has to be established before anything more comes out. Many Paddington houses were divided into flats over several decades, and openings were sometimes formed without records or approval. The engineer looks for earlier beams, short bearings and unsupported ends before designing new work, because a fresh opening in a wall already carrying an undersized beam is a different calculation entirely.
By settling the route before the beam is ordered. Streets around Paddington carry heavy traffic, controlled parking and in places a red route, so a beam cannot simply be unloaded at the door. We arrange the permits and the timing, and where the frontage will not take a delivery the engineer is asked at design stage for a spliced beam that arrives in shorter lengths.
The stack above has to be carried before the wall goes. In Paddington terraces the breast frequently sits within the wall an owner wants opened, and the masonry above it continues to the roof, so the beam carries the stack as well as the floor. The engineer sizes for that combined load. Where the stack is shared with the house next door the Party Wall etc. Act is engaged.
It depends on what caused it, which is why condition is recorded first. Where the Party Wall etc. Act applies to your Paddington property, the surveyors document the neighbouring property before work starts, and any claim is assessed against that record. Damage caused by the works is the responsibility of the building owner, whose contractor carries public liability cover for exactly that situation.
