The Barber Vintage Motorsports Museum houses the largest private collection of motorcycles in the world, and the museum is conceptualized as a minimal vessel of concrete, steel, and glass to protect and display the historic vehicles. The museum addition provides an additional 70,000 sf of display and maintenance space, linked directly to the center of the existing museum. The dramatic three story atrium is terminated by a cantilevered spiral stair wrapping around a glass elevator uniting the museum levels and encourages visitor exploration through the museum.

The stair and elevator required considerable study, both aesthetically and structurally, and changed numerous times during the design process. The final form is dramatically cantilevered around the elevator, a sweeping expression of cast-in-place concrete. The elevator has glazing on three sides, directing views to the outside, while a vertical concrete face provides the terminus to the atrium.
