The Architects Journal reports that Landec, the site owner, appointed Threesixty Architecture to replace Foster + Partners on the project to develop the 1990s structure on Buchanan Street.

The building was originally designed by Jenkins & Marr Architects and the new designs are yet to be revealed.

Threesixty is understood to be working on an approach which will reuse the existing structure.

The practice’s managing director Alan Anthony told The Architects Journal: “Plans to work with the existing shopping centre and adapt it to be more generous and engaging to the street will more quickly achieve the transformation of the ‘top of the town’ and with far less disruption to our city centre.

“By creating relevance and greater resilience, this could well offer a blueprint on how we might reinvent similar structures that dominate many instances of our urban centres.”

Landsec had scrapped plans from Foster + Partners last October after favouring a redevelopment of the structure instead of a demolition and rebuild.

The firm has said it is looking for a new masterplan for “rejuvenating Glasgow’s prime retail destination”.

The company’s head of retail development, Nick Davis, said: “Given the way cities have changed, and retail’s strong post pandemic recovery, we’re exploring a masterplan that can be delivered in incremental phases.

“In conversations with brands, and through engagement with the public, we know that there is both consumer and commercial appetite for this to be delivered and delivered quickly.”
