Constructed for Lloyd Logan, a prominent Winchester tobacco merchant, the house was used as headquarters for Union generals Philip Sheridan and Robert Milroy during the Civil War. The imposing Greek Revival brick building on a raised basement has a shallow-pitched hipped roof, frieze attic windows, and six-over-six sash windows topped by wooden lintels with bull's-eye corner blocks. The two-story five-bay portico with full-height Corinthian columns and a full entablature was added c. 1915. From 1874 to 1909 the building housed the Episcopal Female Institute.
