The OS Kelly Mansion. A little Springfield Historic Trivia. Fountain Ave was named for OS Kelly as he donated fountains that are downtown. In The Springfield Historic District, this massive home is waiting on a talented person to renovate and put back to it's former glory. Home is located across and down street from Kuss Auditorium, a Concert and Performing Arts Venue and Clark County Library. This gem is a blank slate with no HVAC. New 100 amp electric panel. 2 Fireplace mantels and some wood trim are in storage. Close to all of the new building and revitalization downtown. Located in the Historic District so there are some rules and regulations that deal with outside of home. (Color of house and trim has to be approved) Fun project to renovate and make this home a showplace.
