The Museum of Modern Art (MoMA) in New York City is getting a surprisingly tall, and stunningly slender, neighbor. Real estate developer Hines is planning a 75-story tower designed by Ateliers Jean Nouvel for a narrow, 17,000-square-foot site directly west of the museum. When complete, the building is expected to rise nearly as high as the 1,047-foot-tall Chrysler Building.

Hines purchased the land parcel from MoMA for $125 million in January 2007. As part of a complicated deal, the museum will be allowed to expand into the second, fourth, and fifth floors of the new building, giving it an additional 50,000 square feet of exhibition space to add to its existing 125,000 square feet.
