Among his sons was Henry Powell, who became wealthy enough to finance the construction of a larger and more ornate house.
[1] At the time of construction, Powell's home was a Greek Revival structure, greatly different in appearance from its present form.
Its structure was profoundly modified in an extensive reconstruction of 1882, performed according to a design by leading Cincinnati architect Samuel Hannaford; by replacing the old roof with a mansard roof and adding a wooden porch, Hannaford destroyed the original Greek Revival styling and replaced it with the Second Empire exterior that remains today.
More decorations are present on the porch than on any other sections of the exterior, due to components such as an exceptional balustrade and an unusually flat mansard roof featuring a cornice with dentils; the structure comprises similar sides that differ substantially from the central section.
[3]: 5 Although it was already part of the district, the house was added to the Register again in 1980, this time by itself;[1] it was part of a group of dozens of buildings designed by Samuel Hannaford, nominated as a multiple property submission due to their place as examples of the work of the most important architect to practice in nineteenth-century Cincinnati.
