The Lobby, Canberra for sale

The National Capital Authority is seeking expressions of interest for the sale of The Lobby restaurant.

The Canberra landmark has been closed for more than a year.

The authority said it would ensure that its heritage values are protected after the sale, NCA chief planner Andrew Smith said.

"Once sold, the NCA and the Commonwealth will remain committed to protecting and preserving the heritage values of The Lobby as well as the Commonwealth Heritage listed landscape which it forms part of," the authority's chief planner, Andrew Smith, said in a statement.

Development of The Lobby would need parliamentary approval.

Smith expects that The Lobby be a hospitality venue, remaining as a restaurant or possibly becoming a bar or cafe.

The restaurant opened in 1968, mostly for politicians who wanted somewhere to dine near Old Parliament House.

The tender process is through Civium Property Group until March 15.
