GS Renovation carries out structural alterations across South Kensington, working within the Georgian and Regency townhouses of the SW7 museum quarter. Over more than 30 years in the Royal Borough of Kensington and Chelsea, we have formed new openings, replaced tired joists, underpinned settled walls and installed supported openings in these grand period homes with the precision they demand.
Structural alterations for South Kensington townhouses
A period South Kensington townhouse throws up a wide range of structural work: a new opening between reception rooms, a wider doorway through a masonry wall, replacement joists where a Victorian floor has sagged, or a supported opening for a rear extension onto the garden. Each starts with our structural engineer assessing what the existing structure carries and specifying the steel or timber to suit.
Where original floor joists have deflected or suffered rot in an older SW7 house, we renew them to engineered spans and improve bearings so floors sit true again. New openings are formed with correctly sized beams on padstones, temporary propping throughout, and staged removal of masonry. We match the works to the age and fabric of the building rather than forcing a one-size approach onto a listed-quality home.
Underpinning and sign-off in the Royal Borough
Some South Kensington houses show signs of historic movement, and where foundations need strengthening we underpin in carefully sequenced bays to the engineer's design, extending support down to firmer ground. This is exacting work in a terrace of tall, heavy masonry, so we monitor as we go and never undermine an adjoining property. Where a shared party wall is involved, the Party Wall Act applies and you serve notice on the neighbour first.
All of this structural work is notifiable under the Building Regulations, and the Royal Borough of Kensington and Chelsea's building control inspects the key stages and issues the completion certificate. Internal structural alterations do not require planning permission; only external work to a listed building or within a conservation area brings in separate consent. We manage the engineer and the inspections as one package.
