Named for the Sugar Loaf Mountain, a conical hill dominating the property, Sugar Loaf Farm is an impressive early-19th-century farm complex. The Augusta County property was acquired by the Summers family in the 1770s. By 1830 David Summers had built the existing primary buildings—the farmhouse, the miller’s house, and the gristmill, all substantial brick structures. Together they demonstrate a high level of craftsmanship and incorporate details, such as molded brick cornices and corbeled chimneys, characteristic of the early vernacular architecture of the region. The original part of the house on Sugar Loaf Farm has a hall-parlor plan with a ca. 1870 I-house addition. The mill, the county’s only surviving brick mill, originally incorporated the principles of Oliver Evans, an 18th-century mill designer. Various other farm buildings and the sites of earlier vanished structures add to the interest of this well-tended estate.
