Although the Allison Inn & Spa's owner originally wanted a series of cabinlike structures, efficient operations demanded a single structure. The four-story building is nestled into the hillside so that it appears as only one story from the entrance.
In the interior of the Allison Inn & Spa, mossy rock from Montana is combined with rapidly renewable aspen fiber flooring. A water feature trickles between the entryway and the 15,000-square-foot spa, which includes 12 treatment rooms, various lounges, saunas, and a pool.
Another visible sustainable effort at the Allison Inn & Spa is the268-panel photovoltaic array that produces about 55 kW to help reduce energy pulled from the grid.
More visible sustainable efforts at the Allison Inn & Spa include a 10,000-square-foot vegetated roof.
In the guest rooms of the Allison Inn & Spa, guests are offered small reusable glass drinking bottles and filtered water to reduce the use of plastic. Each floor has recycling bins for paper, plastic, and glass. And, as is becoming customary in many hospitality properties, guests are given the option to not have their sheets washed every day.
