In Columbus, in addition to the Lunatic asylum, Blind school and Statehouse. Kelley was responsible for the Franklin County (Ohio) Court House (1840), many schools and churches, commercial buildings, and a variety of private residences. His residence for Benjamin E. Smith, one of his last active commissions, was completed in 1871, and is still in use as a home for The Columbus Club. Another surviving building is the Hayden Block, a yellow sandstone building on Broad Street directly to the north of the statehouse. Originally a bank and office building, it still is used for those purposes. A powerhouse for the city of Columbus, begun soon before his death and completed by his son James, was located near the Scioto River, on land that is still used by the city for a utility complex. Careful observation of the site indicated the abandoned powerhouse in ruins that are still standing.
