Built on the flat floodplain of the South Fork of the Shenandoah River, this two-story stone house was named for its whitewashed stucco covering. Local tradition identifies this as a dwelling and meetinghouse built by Swiss Mennonite (later Baptist) minister Martin Kauffman II about 1760. It now has a two-room Rhenish American plan with an internal chimney that originally served as a cooking fireplace in the Küche and a stove in the Stube. A third room to the west may have been removed in the remodeling that followed local convention in converting the old rooms into more refined spaces with neoclassical woodwork, plastered walls and ceiling, and fireplaces used for heating rather than cooking.
