The proposals will see the provision of a 12-storey new build element, incorporating 130,000 sq ft of Grade A office space on Bath Street, as well as the remodelling and refurbishment of a second building, formerly home to retailer BHS.

Improvements to a third premises located on Sauchiehall Street will take the total area covered to 240,000 sq ft.

A portion of the BHS site has been tabled for demolition to make way for the new building, with the remaining construction set to house around 80,000 sq ft of office space above the existing retail offering. Interiors will be carefully designed to complement the contemporary exterior which will have an industrial feel, featuring elements of exposed brickwork.

The properties were acquired last year by Formal Investments.

Director Nicholas King said: “This proposal shows a really exciting vision for an important site in Glasgow city centre and will provide the highest quality environments for retailers and businesses large and small.”

The architectural design work for the redevelopment has been carried out by Glasgow practice Stallan-Brand.

Associate Patrick Wilson said: “Formal Investment’s proposed redevelopment presents a unique opportunity to revitalise and transform the quality of the urban environment and public realm in this location, through the creation of new public spaces and improved and more appropriate mixed use activity.”

Gleeds will be responsible for assisting with the appointment of additional consultants as well as managing the entire programme of works.
