YOUNGSTOWN — The city’s design review committee approved exterior plans for three projects: the Penguin City Brewing Co., Stambaugh Auditorium and Ohio Urban Renaissance. Penguin City bought a former Republic Steel warehouse at 460 E. Federal St. for $575,000 in December and is planning a $3.7 million renovation. The 32,704-square-foot location should open in September or October, Annissa Neider, the project’s architect, told the committee at a Tuesday meeting. The exterior work includes painting, replacing broken windows and panels, installing a front patio with fencing, improving the parking lot and doing landscaping. New signs will be placed on the building including one on the south side that will read: “Tough times don’t last, tough cities do!”
