The masterplan, drawn up by Leslie Jones Architecture proposes an urban network of streets, based on historic street layouts.

Given the scale of the proposed development, the current expectation is that phased works will take 15 to 20 years to complete, with elements of the existing St Enoch Centre remaining operational during this period.

A new St Enoch Street and the square are the main features of the scheme, providing public realm and connectivity between the city and the Clyde.

Guy Beaumont, director at Sovereign Centros, said: “This marks a milestone moment for St Enoch Centre and underlines the council’s commitment to meeting the needs and demands of people who live and work in the city centre.

“It’s an exciting time for Glasgow city centre and with a clear strategy and appetite for improvement, there is an enormous opportunity to create something truly special. We will now begin to refine the proposals, in line with our consent.”

With the Scottish Government aiming for Glasgow to become carbon neutral by 2030, social, environmental, and economic factors are at the forefront of Leslie Jones Architecture’s proposals.

The masterplan retains part of the site, including the listed Debenhams Building, the listed Buck’s Head Building, and traditional masonry facades on 135 – 153 Argyle Street, which are to be incorporated in the new layout.

This latest redevelopment plan comes as developer Landsec is working up plans to demolish the Buchanan Galleries for an £850 million mixed-use development.

It is estimated the Buchanan Galleries redevelopment would take place over 10 years, with the work being hoped to start next year if approved.
