As London’s 2012 Olympic Games approach, the 8,425-sq-meter, curved roof over the new West Concourse at London's King's Cross railroad terminal is now fully exposed from the inside for the first time. Until recently, the soaring, $295-million roof had been obscured by more than 1,000 tonnes of erection supports, which now have been taken down.
The 12,000-tonne, steelwork diagrid roof is the dominant element of an $820-million program to renovate and enlarge the age-worn, 159-year-old station in time for this summer’s Olympics.
