MAJOR investment is being proposed for a B-listed Glasgow City Centre building, including adding two floors.

The redevelopment would create 2,300 square metres of grade A speculative office space at 101 St Vincent Street, on the corner with Renfield Street.

The existing upper three floors of derelict office space would be refurbished as would the ground floor shops. The current attic space and roof would be replaced with two floors of open plan flexible office suites.

A statement lodged with the planning application explains: “While all the new work has a modern language, [architects] McGinlay Bell have taken great care to respect the history of the existing building.

“It is therefore submitted that the proposals represent a major investment in the city centre providing commercial opportunities and indeed will strengthen the city centre’s appeal as a destination for business while also enhancing the built environment.”

A two-storey extension to the building using a different design was approved in 2009.

The new application is pending assessment by Glasgow City planners.
