Southwark Underground Station was opened in 1999 as part of a £3.5 billion project to extend the Jubilee line and has since been praised as a British rival to the Moscow Metro’s impressive architecture.
But a group of architects have grown concerned over plans mooted by Transport for London to flatten the station in Blackfriars Road to make room for 300 homes.
The plans for the one-acre site, which currently houses disused office and empty space around and above the station, also includes restaurants and shops.
North Greenwich station could also be changed, with new plans for a “winter garden”.
Southwark's glass ticket hall was initially designed to be built over with 11 extra storeys, but architects say the new proposal will be “completely out of scale”, The Times reported.
