Welliver planned, managed, and restored the three-story, 150-year-old building. The museum hosts artifacts, educational displays, art exhibits, conferences, a gift shop, and employee offices. The building, last renovated in 1982, received an entire interior overhaul along with an addition and a terrace overlooking the City of Corning.
The parking lot also received a new look resembling a Western motif. In addition, Welliver renovated and updated the Cantina space located on the street level of the museum.
- The interior mahogany stair configuration was returned and restored to the original layout with a rustic look to make a world-class lobby and welcome area.
- The renovation created a world-class museum atmosphere used to display new exhibits and large enough to accommodate additional visitors.
- Ten separate gallery spaces were renovated to house permanent and temporary exhibits of various western subjects and art collections.
