Hyatt Regency Hotels have been known for their soaring atriums. Since the trailblazing design by John Portman, FAIA, for the Hyatt Regency Atlanta in 1967, this architectural element has become a signature for the company.

Views from the Grand Hyatt Washington's atrium include the skylight thirteen stories above and the two-story fountain and 27,000 gallon lagoon below. The 900+ rooms in the upper stories look either out, toward the city, or in, toward the courtyard.

As a convention-oriented hotel located in the Penn Quarter neighborhood of Washington, DC, there are five levels below the main floor and 42,000 sf of function space. The exterior of this hotel has a stone-like base, metal-framed window bays, and mansard roofs.
