The CMG headquarters is my favorite Koolhaas building.  It is a 51 story skyscraper with an incredibly unique geometric shape. Locals affectionately refer to it as the “big pants”, which I find hilarious. The building consists of six horizontal and vertical sections in a loop.  It won the 2013 best tall building worldwide award from the Council on Tall Buildings and Urban Habitat. Construction began in 2004 and was completed in 2012. It is the headquarters of the China Media Group.
