In 1768, the widow Grissell Hay advertised this carefully ordered, frame Georgian-plan house facing Market Square as offering “very commodious lodgings to be let for a dozen gentlemen.” Its size and regularity suggest a 1760s date, though both archaeological excavations and dendrochronology, or tree-ring dating, appear to support the long-held belief that it is an early eighteenth-century house. The porch is a Greek Revival addition, and the four rear outbuildings date from the late eighteenth and early nineteenth centuries. These are the most recognized ancillary buildings in Williamsburg, largely because of the picturesque use of deepcoved eaves above the ventilation louvers on the dairy.
