GS Renovation carries out structural alterations across Chelsea, from new openings in the spine walls of Georgian terraces to replacement joists and supported openings in listed SW3 homes. With more than 30 years in the Royal Borough of Kensington and Chelsea, we handle the engineering, the consents and the building control sign-off as one team.
Structural alterations for Chelsea period homes
The Georgian and Regency townhouses around the King's Road were built with solid masonry walls and timber floors, and after two centuries those joists and lintels often need attention. Whether you want a wider opening between two rooms, replacement joists for a sagging floor, or a new door punched through a thick brick wall, the work has to be designed so the load is safely rerouted rather than simply weakened.
We start with a structural engineer who sizes any new steel or timber, specifies the padstones a beam bears onto, and details the temporary propping needed while we cut the opening. On the tall Chelsea houses where foundations are shallow or a bay is settling, that same assessment covers underpinning, so the whole scheme is designed together rather than patched piece by piece.
Consents and sign-off across the Royal Borough
Internal structural alterations are notifiable under the Building Regulations, so the Royal Borough of Kensington and Chelsea's building control inspects the works and issues the completion certificate. Because so much of Chelsea's SW3 stock is listed or sits within a conservation area, any change touching the exterior, or in some cases altering the internal fabric of a listed home, needs separate consent, and we guide you through which route your project takes.
Where an opening or a new beam involves the party wall shared with the house next door, the Party Wall Act applies and notice must be served before we begin. We manage the engineer's drawings, the notices, the building control application and the safe staged execution on site, keeping a single point of responsibility from first survey to final certificate.
