CCTV Headquarters, China, by OMA

Beijing's CCTV Headquarters is a 54-storey high-rise by Rem Koolhaas' studio OMA, which is designed to challenge the traditional shapes of skyscrapers.

Two towers lean towards each other and connect at the top by a 75-metre-long, cantilevered linking element. Because of its unusual design, the building is considered a significant work of deconstructivist architecture and has been nicknamed "big pants" by locals.
