ZM Architecture has proposed turning 50 Argyle Street into 13 flats in a programme of partial demolition, extension and repair for the Blailok Group.

Under the proposal, retail space will be retained at ground and basement levels.

The applicant Innovative Asset Management bought the building last year.

A design document submitted with the application states: “They are committed to repairing and preserving the building through pragmatic and careful conservation-based intervention. They have a track record of delivering successful projects in the UK to meet market opportunity and demand.”

A report commissioned in 2015 concluded — after intrusive investigation — that the building had “come to the end of its useful life”, was “incapable of repair short of complete dismantle/reconstruction” and should “therefore be demolished”.

Plans were lodged to knock the building down and replace it with student accommodation but, while it was being used as a giant advertising space, it was realised that restoration was viable.

An application to turn it into 21 flats was approved by the city council in August 2019 but was never implemented.
