It keeps original features such as a pedimented attic, a full entablature with a dentil-like course made of round wooden pegs, and a fluted-pilaster side entrance. It is also tied to the College Farm, owned by Harvard from 1728 until Hardy bought it in 1839.","narrative":"Standing at the corner of Lexington Street and a quiet residential street in Waltham, this clapboard house was built around 1845 for Nahum Hardy. It is a 2½-story, side-hall plan Greek Revival dwelling with a two-story rear ell. Its details include a pedimented attic, pilastered cornerboards, two side chimneys, floor-length first-floor window architraves, original 6/6 sash and a gable-end entrance with fluted pilasters and sidelights. Its entablature carries an unusual dentil-like course made of round wooden pegs, matching that on the 1845 Amos Stearns House and suggesting the same carpenter. The land was long known as the College Farm because Harvard College owned it, leasing it to tenants. Hardy became the tenant in 1819 and completed his purchase in 1839. The house is valued as one of few Greek Revival buildings in an area of twentieth-century homes and for its preserved design, materials and workmanship. A granite retaining wall and granite driveway posts set it off from the street.","period_of_significance":null,"architect_builder":null,"architectural_style":"Greek Revival","criteria":["C"],"status_note":"Condition is described as good, with residential use and no major alterations noted; later additions include dormers, a portico and ells.
