The Doha Convention Center Tower is a on-hold 551 m (1,808 ft) tall skyscraper project which was planned to be constructed in Doha, Qatar. The structure, shaped like a tapering obelisk, would have housed offices on the lower levels, apartments, a hotel and penthouse residences on the upper floors. At the very top, a private club was to occupy a 60 m (200 ft) high glass cylinder surrounded by extensions of tower's façade and supported by a structural helix.
