A dramatic double-height, client-exclusive club on the top floors will include spaces to dine, connect, and collaborate indoors and out, with striking terraces and expansive views overlooking Midtown. A robust food and beverage program including a lobby café and bicycle storage with cabanas and showers round out the amenity program. Specialty floors including private terraces and elevated ceiling heights allow clients to design a multi-functional workplace that accommodates a variety of work styles and space needs.
