Situated along South Temple Street near Temple Square, the design maintains significant architectural characteristics while incorporating contemporary elements. Neoclassical-style arched openings and materials that echo the colors and textures of Salt Lake Valley are included. Amenities comprise a resident lounge on the seventh floor, an outdoor pool deck, a fitness center, a pet lounge, and a rooftop lounge on the 25th floor offering sweeping views.
