The Nannie Harmon Howard House is one of Floyd's most impressive residences, a grand Georgian Revival mansion built for the widow of Judge Waller Howard according to plans adapted and drawn by Lather Hylton. The home was outfitted in grand style with a sweeping center staircase featuring elegant stained glass at the half-story landing, where the stair splits and winds in two directions to the upper level. It has six fireplaces, two made of local Floyd County soapstone. Its roofing has individual tin fish scale shingles, and its large wrap-around porch is graced by a prominent portico and gabled pediment supported by cypress wood Corinthian columns in two clusters of three. Bringing the columns to Floyd was a monumental feat, first by train from Chicago and then from the Christiansburg Depot by twelve yoke of oxen. The house remains a private residence.
