With gallery space where artworks will be sold in front, backed by two ballet studios and a black box theater, a large building that previously held a small shoe repair shop has been transformed into the first of three envisioned new facilities of the Averitt Center for the Arts. For now simply the Center for Performing Arts, the building at 41 W. Main St. is available for naming in honor of a major donor as Averitt Center supporters campaign to raise funds. Completing the three new centers, as renovations of existing downtown buildings, is projected to require about $1.8 million over several years, but not all of it is expected to come from donations.
