Royal Borough of Kensington & Chelsea
Timber Sash Windows Chelsea
Heritage and conservation specialists serving Chelsea, Cadogan Estate and Royal Hospital conservation areas
Chelsea sits within the Royal Borough of Kensington and Chelsea, which designates 38 conservation areas covering over two thirds of the borough. In Chelsea specifically, the Cadogan Estate, one of London's largest privately managed estates, encompasses much of the area between Sloane Street and Chelsea Embankment, with dense concentrations of Grade II listed Victorian and Edwardian terraces where Listed Building Consent is required for any window replacement. The streets around Chelsea Square, Cheyne Walk, and the Royal Hospital Road conservation areas contain some of the most carefully monitored heritage streetscapes in London.
Our Heritage Sash Windows are the standard specification for listed Chelsea properties, solid framed glazing bars, putty-fronted slimlight glazing, cords, weights and pulleys, with LBC documentation supplied as standard. Where heritage officers require the absolute minimum glazing thickness, our Vacuum Glazed profile at 8.3mm is the only specification that satisfies that requirement without altering the sash sections.

Why Chelsea requires a specialist
The Cadogan Estate has its own design guidance for window replacements on estate-managed properties, which goes beyond standard RBKC planning requirements. Leaseholders on the estate typically require both landlord consent and planning permission before work can begin. Our survey process identifies which consents are required and we prepare the necessary documentation, including estate landlord specifications where applicable.
RBKC heritage officers are among London's most experienced and apply detailed scrutiny to window replacement proposals. Our specification documentation is prepared to the standard expected by RBKC, scaled section drawings, glazing build-up schedules, and a written statement of compliance.
