9. ONE YEAR ON SHARD REMAINS A SHELL
London’s Shard skyscraper remains mostly unoccupied a year after its grand opening, says The Guardian. Of the 25 floors of offices, 20 are currently unoccupied, with Wall Street firm Duff & Phelps the only tenant. The Shangri-La Hotel, between floors 34 and 52, has yet to open, despite a scheduled launch of last summer.
