A decades-old DoubleTree has been thoughtfully transformed into a boutique hotel that includes 204 guest rooms, a spa deck, expanded event spaces and all-new restaurant and bar venues. The hotel’s renovation faced aggressive timelines, incomplete documentation and almost daily design changes.
During the first phase of construction, the hotel remained partially open to minimize revenue loss during the busy ski season. However, since the building stair-steps up the mountain, its vertical circulation is fragmented, preventing guests from traveling from the lobby to the top floor without switching elevators. This configuration created issues with access, phasing and material movement.
With no continuous floors and limited exterior access, crews had to rely on two aging elevators for vertical movement. Creative logistics planning became vital, and a detailed sequencing strategy assigned time blocks and material types to each elevator daily to avoid bottlenecks.

Building a temporary mountain access road facilitated steel and other material deliveries to the jobsite. It also eliminated the need for crane staging in order to build the spa deck.
Unexpected field conditions were constant. Although the drawings included 20 room types, nearly every room had a unique layout due to decades of modifications. Crews often had to rework scope in real time to align finishes, casework and systems.
Inside the walls, the team encountered residential-grade copper piping and insufficient electrical capacity, requiring a full transformer upgrade and 22 new conduits routed to multiple roofs. MEP routing was premapped to reduce delays and ease installation.
All HVAC, electrical, lighting and glazing systems were fully replaced and all lighting is dark-sky compliant. Crews repurposed a mechanical shaft that was not going to carry the 22 new conduits from the upgraded transformer to rooftop units, which helped avoid additional demolition.
Since the building had never been designed for air-conditioning, upgraded electrical rework to support a new cooling system required all new conduits and complex switchovers.
