The main (1820) portion of the house is a two-story stucco-faced brick structure on a stone foundation. The corners of the three-bay house are thickened by pilasters, with a similar frieze-like thickening extending horizontally above the second floor windows. The front, or south elevation has a small portico with a flat roof and four Ionic columns. The front door has sidelights and an overlight, echoed by the second floor window immediately above the portico. The east and west ends have stepped gables with central chimneys and the "shadow" of a porch. A small 2½ story structure to the north of the main house connects to the main house with a two-story link. This structure has a gabled roof with dormers and is also stuccoed. Its windows are late 18th century in detail.
History
Lewis William Washington (November 30, 1812 – October 1, 1871) was a great-grandnephew of President George Washington. He is most remembered today for his involuntary participation in John Brown's raid on Harpers Ferry, Virginia, in 1859. He was taken as hostage and some of his slaves were briefly freed. (See Black participation in John Brown's Raid.) As he outranked the other hostages he was their unofficial spokesperson, and he testified in Brown's subsequent trial, and before the Senate committee investigating the raid.
Lewis William inherited several relics of George Washington, including a sword allegedly given by Frederick the Great to Washington and a pair of pistols given by Lafayette. John Cook, who served as John Brown's advance party at Harpers Ferry, befriended Washington and noted the relics, as well as the slave population at Beall-Air. Brown was fascinated with the Washington relics. During Brown's raid on Harpers Ferry a detachment from his force led by Cook seized the sword and pistols along with Washington at Beall-Air, taking along three of Washington's slaves. The hostages were taken to Harpers Ferry by way of the Allstadt House and Ordinary, where more hostages were taken. All survived their captivity, and Washington identified Brown to the Marine rescue party. During the assault on John Brown's Fort, a saber thrust by Marine Lieutenant Green at Brown was allegedly deflected by the belt buckle securing the Washington sword.
