A four-story grand staircase was created from metal and then finished in lath and plaster at the Allison Inn & Spa.

The Allison is a 155,000-square-foot building housing 85 luxury hotel rooms, a 600-square-foot restaurant and bar, 12,000 square feet of meeting rooms and ballrooms, and a 15,000-square-foot high-end spa. It is located in the wine country of Yamhill County.

The hotel wing is a three-story, cast-in-place concrete structure with a fourth floor constructed of cold-formed metal framing. The entire fourth floor is a combination of load-bearing partitions and shear-wall framing with an engineered light-gauge metal truss roof system.

A standout element of the building is its four-story grand stairway, which was created out of radiused metal and is bound by a glass curtainwall system. The support beams, columns and entire ceiling had to be finished before any glass could be installed.

The stairwell was originally designed to be clad and finished in drywall, but after several tests, it was determined that lath and plaster would be the best choice for its radiused surfaces.

Other finishes throughout the project included wood, stone, copper and fabric.

Judge’s comment: “This is a great example of exemplary craftsmanship by the Harver Co. With the variety of luxurious finishes and architectural features, the dimensioning and finishing had to be of the highest standards.”
