36 Central Park South was a proposal for a new 88-unit residential tower which would have replaced the 46-story, 628-key Park Lane Hotel. The slender tower sits atop a through-block winter garden, which serves both as an extension of Central Park and as a means to elevate the tower views. Six levels of staggered "treehouse floors" sit above the winter garden as all-glass units, cantilevered toward the park. Three floors of below-grade space include extensive amenities, while residential units above have amazing views of the park.
