In 1784, the original tract of 1,150 acres was granted to George Walton, one of the three Georgia signers of the Declaration of Independence. The land was sold to Thomas Wingfield in 1786, and Peacewood Farm was constructed in 1790.

Peacewood Farm is a compelling example of a residence assembled and expanded across different periods. The original 1790 structure was built in the Plantation Plain style typical of the era—a two-over-two design featuring a front porch and a shed roof extending over two rear rooms. In 1833, the house was enlarged and rebuilt in the Greek Revival style, highlighted by a columned portico.

Several historic outbuildings have survived and been restored, including a smokehouse, kitchen, well house, squab house, and dairy barn. Together, these structures contribute to Peacewood Farm’s enduring significance within Washington’s architectural and agricultural history.
