O.C. Tanner Flagship RenovationSubmitted by Reaveley Engineers + Associates The historic Salt Lake City Library, built in 1905, was converted to a planetarium in 1965 and many of the original architectural features were lost. After the planetarium closed, O.C. Tanner purchased the building for conversion into its new flagship retail store.
The renovation included a seismic upgrade of the historic building, restoration of the exterior stone cladding, historic woodwork, cast-iron columns, plaster walls and ceilings, and the steel roof trusses. The addition of a spiral staircase, a two-story glass wall, and new electrical and mechanical systems created a modern building suited for the O.C. Tanner Flagship store.
