Increasingly Beijing is a city of contrasts. Formerly; mostly a low-rise city; today the skyline increasingly is dominated by a mixture of high-rise architectural design. Tuanjiehu Park is an area of water and traditional Chinese buildings; but beyond rises the skyline of Beijing's CBD. This includes Rem Koolhaas' twisted take on the skyscraper that today is the 234 metre 51 story HQ of CCTV/CMG (China Media Group).
