Thermo Companies purchased the Union Pacific Building and redeveloped it as office and restaurant space. The ground floor became home to the Denver ChopHouse and Brewery, and the second floor became the corporate offices for Thermo Companies. A penthouse was added to the building and it is now home to McPherson Architecture. The building had been neglected over the years, and the design team encountered boarded up windows and a decayed interior that was a rabbit warren of small offices and work spaces. The design concept was to keep a sense of the past and the exterior walls were left as the designers found them; elegantly decayed. The interior space harkens back to town squares and front porches; and the cornice detail at office fronts houses mechanical ductwork. The penthouse was added to the structure with girded trusses that are suggestive of old railroad trestles and the birth of the industrial age. The steel staircase was designed to be exuberant, and economical at the same time. The completed project is a unique work environment and quiet oasis adjacent to Coors Field.
