Ohio One-Ohio Edison
Also known as: Ohio Edison Office Building
Why it's listed
Built in 1930-31 at 25 East Boardman Street, this six-story U-shaped office building served as the Youngstown headquarters of Ohio Edison, which that year consolidated the city's electric utility companies. Its limestone base, brick upper floors, monumental arched entrance and balustraded parapet reflect the Georgian Revival style. Inside, Customers' Hall has black walnut paneling, fluted columns, a coffered ceiling and a terrazzo floor bordered with imported marble, while the elevator lobby is finished in travertine and Tennessee marble. A giant rooftop neon sign used a newly developed dimming device to shift from white to red, and the sign remains, rearranged to read Ohio One. Ohio Edison occupied the building until 1975, when it was sold. The building survives largely unaltered and is still used as offices. It is also one of the few early twentieth-century commercial buildings left east of Market Street, where urban renewal cleared much of downtown in the 1960s and 70s.
Significance in brief: The nomination argues it is significant for its link to local electric utility history, since Ohio Edison consolidated the city's utilities in 1930 and occupied the building for 45 years. It is also a good example of Georgian Revival office architecture with quality materials and technological innovations such as a color-changing neon sign. It is one of few buildings remaining east of Market Street after urban renewal.
