This modern luxury apartment building is much simpler than the historic buildings that surround it. Its sleek glass facade is punctuated by two deeply shadowed notches. Each notch marks a floor with lavish tenant amenities: the 10th floor has a gym and swimming pool; the 32nd floor has a club room and lounge. Both areas have great outdoor terraces. The crowning space is the 41st-floor rooftop deck. It features lush plantings, fire pits and a hydrotherapy pool—not to mention one of the city’s most stunning views.
