Halladay Farmhouse
Why it's listed
This farmhouse sits on a 92-acre farm along Route 20, the Western Turnpike, in the western part of Duanesburg. Believed to date from about 1786, it was remodelled in the 1830s into a one and one-half story, five-bay frame house with a gable roof and brick end chimneys. Its Greek Revival details include a wide frieze, broad corner pilasters, and a recessed entrance with sidelights, transom and a heavy entablature. The frieze is pierced by eyebrow windows with ornate iron grillwork, a feature found on only a few buildings in the town. The plan shows a three-bay house with a side entrance expanded into a full five-bay width, a pattern documented elsewhere in the area only at one other house. Six nineteenth-century frame outbuildings, including two large barns, a machine shop, a carriage house and sheds, survive and reflect the continuous agricultural use of the land. Aluminum siding was added, but the house keeps substantial integrity.
Significance in brief: The nomination presents it as a representative vernacular Greek Revival farmhouse, notable for its eyebrow windows with intact iron grillwork, a feature found on only a few Duanesburg buildings. It is also an example of a finished "two-thirds house" expanded to five bays. The surviving nineteenth-century outbuildings and the historic farm setting add to its significance.
