A cast-iron street clock and cobblestones at the entrance of this boutique hotel announce the mid-century grandeur inside. Sitting on a triangular city block at the border of TriBeCa and SoHo, the uncommon architecture creates a formidable interior. The amber-hued décor of the central atrium, inspired by Frank Lloyd Wright’s work, basks in natural light from an eight-story-high glass ceiling. The soaring space, encircled by 201 fully-equipped custom suites, evokes a sense of awe and tranquility.
