Ultra-new, ultra-luxurious, and ultra-hip is how this sleek building can be described. The facade of the 15-story building is constructed of glass, stone, and blackened stainless steel. Several penthouse units sit on the tops floors of the building, while nine smaller residences are below that. Amenities include a full-time concierge, outdoor garden with a private lounge and kitchenette, refrigerated storage, a pet wash station, and available storage units.

Located in the Flatiron district, the building is close to Madison Square Park and high-end shopping on Fifth Avenue. Residents enjoy the Union Square Greenmarket with its local produce, and diners flock to the legendary Shake Shack restaurant. Eataly, the Italian food market loved by chefs and home cooks, is also in the neighborhood. The building is also just steps away from the rest of the city, with the subway system easily accessible.
