Strolling along Central Park West in the West 60s, the pedestrian passes a pale limestone building that rises quietly and majestically from the sidewalk, creating a dignified, civilized mood on the street. Curving, carved limestone moldings frame windows and doorways. At the main entrance, which is two stories high, a graceful canopy announces "Fifteen Central Park West." From a distance, its limestone tower co-exists happily with the neighboring Art Deco towers of the Century apartment building next door. At the top, its romantic, asymmetrical silhouette features swooping inverted arches and a loggia like those from the 1930s that hide unsightly water tanks. This elegant building is not a classic from the 30s, but rather a recent welcome addition to the iconography of great New York City apartment buildings that was built in 2007, and is one of the most-coveted and exclusive residences in New York City.
