The Citigroup Center

The Citigroup Center (formerly Citicorp Center) is one of the tallest skyscrapers in New York City, United States, located at 53rd Street btw Lexington Avenue and Third Avenue in midtown Manhattan. The 59-floor, 915-foot (279-m) building is one of the most distinctive and imposing in New York's skyline, with a 45° angled top and a unique stilt-style base. It contains 1.3 million square feet (120,000 m²) of office space, and the 45-degree angle at the top of the building was originally intended to contain solar panels to provide energy; this idea was eventually dropped because the positioning of the angled roof meant that the solar panels would not face the sun directly. It was designed by architect Hugh Stubbins Jr. for Citibank, and was completed in 1977.

Time Warner Center

The Time Warner Center is a mixed-use skyscraper developed by The Related Companies in New York City. Its design, by David Childs of Skidmore, Owings & Merrill, consists of two 750 ft (229 m) towers bridged by a multi-story atrium containing upscale retail shops. Construction began in November 2000, following the demolition of the New York Coliseum, and a topping-out ceremony was held on February 27, 2003. It is the property with the highest-listed market value in New York City, $1.1 billion in 2006.

Originally constructed as the "AOL Time Warner Center," the building surrounds half of Columbus Circle in Midtown Manhattan. The total floor area of 260,000 m² (2.8 million ft²) is divided btw offices (notably the offices of Time Warner Inc. and an R&D Center for VMware), residential condominiums, and the Mandarin Oriental, New York hotel. The Shops at Columbus Circle is an upscale shopping mall located in a curving arcade at the base of the building, with a large Whole Foods Market grocery store in the basement. The complex is also home to a 1,200 seat theater for Jazz at Lincoln Center as well as CNN studios, from where Anderson Cooper 360°, among other shows, are broadcast live. CNN's Jeanne Moos, known for her offbeat "man on the street" reporting, frequently accosts her interview subjects just outside the building. In 2005, Jazz at Lincoln Center announced a partnership with XM Satellite Radio which gave XM studio space at Frederick P. Rose Hall to broadcast both daily jazz programming and special events such as an Artist Confidential show featuring Carlos Santana.
