Sir Terry Farrell has launched a last-ditch bid to save his Comyn Ching Triangle in Covent Garden.

The architect restored the listed Georgian houses that form the site and inserted Postmodern elements to the structures between 1978 and 1988, but he now fears alterations to the buildings, devised by Morrow + Lorraine Architects, could threaten their architectural fabric.

Adam Nathaniel Furman, a researcher at Farrell’s practice, has been working on the listing bid, which has been submitted to Historic England. ‘We really do hope that with this one we can set a precedent that Postmodern architecture is worth protection,’ he told Building Design.

Preservation group The Twentieth Century Society has also backed Farrell’s bid. In a letter to Historic England, senior conservation adviser Henrietta Billings described the site as ‘an important and influential example of Postmodern urban development that fully deserves recognition and protection through listing’.

This isn’t the first time Farrell has attempted to preserve his own Postmodern architecture, having submitted a listing bid for 76 Fenchurch Street, which is also set for redevelopment.
