The Williamson Building was constructed between 1891 and 1904 and is a representative example of the commercial construction which occurred in the late nineteenth and early twentieth century when Cincinnati's central business district expanded outward. The Williamson Heating Company occupied the first floor while the Globe Overall company factory housed the second to fifth floor.

Purchased in 2001 by Middle Earth Developers this warehouse underwent commercial to residential conversion creating 26 market rate apartments. July 2006 Huff Realty listed the condominiums, ranging from $130,000 to $278,000. This is the first apartment conversion in the Central Business District. All units feature garage parking and storage units. With immediate occupancy, and loads of space, these condominiums are the best deal in town!
