Cooper, Samuel, Farmhouse
Also known as: Del-671-2
Why it's listed
Built in 1820 on a Radnor farm in Delaware County, Ohio, this two-story house is made of coursed limestone rubble quarried from a hillock on the property. Its form is a Classic I-house with a central hall, but its facade is unusual, with four bays across the upper level and three across the lower, which suggests a transition between earlier and later I-house types. A one-story rear ell was added in 1833, and an Italianate-style porch was probably added around 1870. Samuel Cameron, a Kentucky-born stone mason who settled in neighboring Scioto Township, built the house for Samuel Cooper, part of the Welsh settlement that shaped early Radnor. The house is the only known stone I-house in the Scioto River Valley of Delaware County and one of three surviving stone buildings there. Inside, original plaster, built-in attic cupboards, the staircase, grained moldings, mantels and flooring remain. The nominated boundary covers only the house.
Significance in brief: The nomination argues significance under Criterion C for architecture. It is the only known stone I-house in the Scioto River Valley of Delaware County and one of only three remaining stone buildings there. Its four-bay over three-bay facade appears to be a transitional form between Pre-Classic and Classic I-houses, and it keeps original plaster, cabinets, staircase, grained moldings, mantels and flooring.
