The General Motors Building, 767 Fifth Avenue, is the crown jewel of the Manhattan skyline located at the southeast corner of Central Park and occupying an entire city block between Fifth and Madison Avenues and 58th and 59th Streets. Its 5th Avenue presence, universal Central Park views, unique marble cladding and modern classic design make it one of the most highly sought after office and retail locations in the world. The Apple "Cube" store on the 5th Avenue plaza has become one of the city's top tourist attractions and a worldwide retailing phenomenon. Measuring over 2.0 million square feet and 50 stories, this irreplaceable and iconic asset was designed as headquarters location by renowned architect Edward Durell Stone and constructed to the highest specifications exceeding most of the design and infrastructure standards of today's newest speculative office buildings. The property is held in a joint venture and Boston Properties' ownership share is 60%.
