Here are 10 colossal buildings that have monster-like proportions:

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.

Piano worked with engineering firm Arup to design 82,000 steel panels of the exact same shape and size to cover the curving roof of the terminal, which gently rises in the middle and lowers at either end.
