GS Renovation installs RSJs and structural steel beams across South Kensington, working with the grand period houses of the museum quarter. With over 30 years of experience in SW7, we remove load-bearing walls in Georgian and Regency townhouses safely, sizing every beam by a structural engineer and clearing each stage with building control.
Structural steel beams for South Kensington townhouses
The tall, thick-walled townhouses of South Kensington were built as a run of rooms, and opening them up to modern living almost always means taking out masonry that carries the floors above. In SW7 those loads are considerable, so a structural engineer calculates the beam and specifies padstones to spread the bearing into the solid brickwork rather than crushing it.
We prop the structure temporarily, cut out the wall in controlled stages, and lift the RSJ into position before easing the load onto it. In a four or five storey Georgian house the sequencing matters enormously, and our teams have done this repeatedly across the Royal Borough of Kensington and Chelsea without disturbing the floors overhead.
Party wall notices in South Kensington terraces
So many South Kensington houses share a party wall with the neighbour, and chimney breasts and dividing walls frequently sit on that shared line. When a beam bears into or near a party wall, the Party Wall etc. Act 1996 applies, which means serving notice on the adjoining owner before work begins. We flag this early so the legal side and the build stay on the same timeline.
Because much of SW7 sits within conservation areas and a good number of houses are listed, we keep structural change internal and reversible wherever we can. Building control inspects the beam, the bearings and the fire protection, and issues the completion certificate that protects the value of a period home when it is later sold or let.
Steel into a museum quarter townhouse
Getting a beam into an SW7 townhouse is a planning exercise in its own right. Many of these streets sit within controlled parking or close to routes where stopping is restricted, so a delivery window has to be booked and then kept. The houses have railed front areas and steps up to a raised ground floor, which makes carrying a long steel through the front door awkward at best and impossible at worst.
The usual answer is the lower ground floor. Most of these houses have a front area with its own entrance, and a beam can go in that way and up internally in sections where the engineer's design allows it. Waste comes out by the same route. Where the frontage is listed or the railings original, we protect them physically rather than trusting care alone, since replacing cast iron railings is a consent job of its own. Neighbours on either side are told when the beam is arriving, since a delivery to a narrow street affects more than one house.
