Hilton Keystone Hotel

Expansion and renovation plans for this 215-room hotel involved the restoration of a 7-story historic building, including conversion of a former two-story banking hall into the main lounge and bar, and the addition of a new structure infilling the adjacent empty lot. The new structure was designed to reflect the detailing of the 1917 Key Building through the articulation of the columns, string-courses, and cornice lines. Building materials included granite and pre-cast stone for the first two floors, and cement plaster for the upper floors.
