Improvements are on the horizon for what could be the worst looking building on McMinnville’s Court Square.Ben Myers, current owner of the old Hargrove building, has requested from the Historic Zoning Commission a certificate of appropriateness (COA) to undergo significant renovation to the building by refurbishing existing windows, replacing the plywood with actual windows, replacing the roof, and stabilizing the crumbing exterior walls.Commission members heard the request Tuesday. Myers asked about the presence of vinyl windows in some buildings downtown. “Our plan is to restore and not replace the windows,” said Myers.
