The CSC, which has served as a social hub for current and former civil servants since 1953, is one of four buildings identified as “non-essential government buildings” by the Labour Party’s ‘Zero-Based Review’.
According to the review, the CSC is estimated to be worth £6.8m.
The other three buildings identified are: Inn The Park, a restaurant estimated to be worth £6.7m; the QE2 conference centre, estimated to be worth over £25m; and Marlborough House, which is currently used by the Commonwealth Secretariat and is estimated to be worth almost £65m.
Shadow chief secretary to the Treasury Chris Leslie (pictured) said: “It is time to consider whether it is necessary for the state to continue owning a restaurant in St James’ Park, a club for the exclusive use of civil servants, or a conference centre.
“Four such buildings in iconic locations in central London could attract interest from buyers around the world.”
A final decision on any sale would be carried out in government, Labour said.
