Henderson Global Investors and Land Securities have submitted an outline planning application to the Glasgow’s city planning department for their Buchanan Galleries extension.

The plan is for the centre to double in size to add 700,000 sq ft (65,000 sq m) which would increase the overall size of the scheme in Glasgow to 1.3m sq ft (120,770 sq m).

The extended Buchanan Galleries will also include a refurbished Buchanan Bus Station which will act as a ‘gateway’ to the city centre from the north.

The scheme will also include public realm improvements, the introduction of new public art and a new atrium entrance at the junction of Sauchiehall Street and Buchanan Street, creating better access to both the shopping centre and the Royal Concert Hall.

Myles White, fund manager for Henderson Global Investors, said: ‘The public consultation emphasises the importance of this project not only for the economic development of Glasgow, but highlights the impact a new centre could have on sustainable tourism in the city.

The centre currently has more than 80 shops including John Lewis, H & M, Next and Gap.
