Westin Mission Hills, Rancho Mirage, CA
Twenty acres of desert resort, redesigned for the way people actually relax.
The Westin Mission Hills brought ACI in for planning, architecture, and interior design across one of the property's most ambitious renovations. A 30,000 sq ft lobby, spa, and public space program, all built around the unique rhythms of a destination resort in the California desert.
The project went on to win the 2006 ARDA Award, a recognition of how planning, hospitality experience, and ex*****on come together to create resort properties that genuinely transform a guest's stay.
Years on, the lesson stands: great resort design pays back for decades.
