CCTV Building, Beijing
Construction of Beijing's CCTV Building was completed in May 2012. The unique structure designed by Rem Koolhaas and Ole Scheeren houses the headquarters of China Central Television (CCTV).
The building's complex design consists of six horizontal and vertical sections that leave a central void. CCTV's unusual design has stirred controversy and praise: Detractors claim it resembles female genitalia, while some critics are calling it the greatest building of this century.
