Buttermilk Base

Buttermilk Mountain, part of the four mountain destination resort of Aspen Snowmass, is located just west of Aspen and is the longtime home of the ESPN X-Games and the main hub for ski and snowboard beginners, children, and families.

All Day Recess: To create a more cohesive guest experience, CCY Architects designed three buildings, Buttermilk Mountain Lodge (formerly called Bumps), Guest Services, and The Hideout, all integrated into the resorts' master plan, developed by longtime collaborator, DesignWorkshop. Collectively these buildings frame an outdoor pedestrian plaza, providing a more intuitive sense of wayfinding to the Summit Express chairlift.

Originally designed and built in 1993, Buttermilk Mountain Lodge was extensively renovated to serve as a slope-side restaurant and bar with a dynamic interior for special events and weddings. The new Guest Services building will add a day lounge while serving as the primary hub for ticketing, retail, and rentals.

Inside Buttermilk Mountain Lodge and Guest Services, light and dark colored woods with white and gray accents provide a neutral backdrop, allowing the wayfinding, furniture, and retail displays to be accentuated in bold branded blocks of color.

With an eye toward optimizing energy performance, sustainable design strategies generate efficient and high-performance buildings at Buttermilk.
