The building was net zero in construction and is in operation, has achieved EPC A and is expected to obtain BREEAM ‘Very Good’ – a rare achievement for a listed building of this scale and age. At the heart of the transformation is Pollen Square, a revitalised public realm that connects Pall Mall to its surrounding streets. “This technically complex project has safeguarded an iconic part of Manchester’s commercial heritage that once symbolised the city’s post-war business ambition. Alex Smith, Partner at Sheppard Robson, said: “Post-war buildings like Pall Mall were the most innovative of their era, pioneering open-plan working. Unlike Victorian buildings, where we understand how to refurbish stone, lead, and timber, with mid-century buildings the industry is still learning how to retrofit them sensitively.
