 Beginning with the construction of One57, a apartment building between Sixth and Seventh Avenues which was completed in 2014, a large number of very tall ultra-luxury residential buildings have been constructed or proposed on the section of 57th Street roughly corresponding to the southern edge of Central Park.Due to the often record-breaking prices that have been set for the apartments in these buildings, the press has dubbed this section of 57th Street as "Billionaires' Row".These projects have generated controversy concerning the economic conditions and zoning policies that have encouraged these buildings, as well as the impact these towers will have on the surrounding neighborhoods and the shadows they will cast on Central Park.
