Start saving now if you want any chance of getting an apartment in this beauty, set to open in 2019. Designed by Pritzker Prize-winning architect Richard Meier, the 556-unit building will be located just south of the United Nations headquarters. 685 First Avenue will feature 408 rentals, 148 condominiums, 69 balconies with city views, a 70-foot lap pool, fitness center, yoga room, children's playroom, game room and on-site parking. But most special is its black glass facade, which will shield the apartments during the day. "You would not see all the drapes and the people inside, so the building looks very uniform," says Dukho Yeon, an associate partner at Richard Meier & Partners Architects.
