Aria Las Vegas in City Center Las Vegas, completed in 2009. The $9 billion project starts with only the mountains, the sunlight and the views. Pelli describes creating the building's own context with complex programs and procession paths. Maya Lin, Jenny Holzer, and other renown designers and artists contributed to this massive project.
The LEED certified 4004-room hotel lets go of the Las Vegas kitch and allows daylight into the deep mall spaces with unique materials and lighting schemes to define exciting spaces. The majority of rooms fit into the gently curving glass building looming into the skylight. It establishes a man-made landscape of crevices and cliffs.
