If the resource is a single building, or a building or buildings are major contributing resources, floor plans of the major levels of the building are required even if the property is not being considered for its architecture (Criterion 4). These need not be done to scale or by a professional architect; hand-drawn floor plans are acceptable.

• Floor plans assist in clarifying the verbal description of the property in Section 7 of the nomination; they also help determine the integrity of the property.

• Floor plans should clearly show any structural changes such as new or sealed door or window openings, and additions or removals such as porches, fireplaces, stairs, or interior partition walls.

This house was built by William Byrd (1674-1744), a planter, public official, and author especially noted for his posthumously published letters and diaries. The brick mansion (ca. 1730-1734) is built in the early Georgian style. It is notable for the quality of its construction and for its completeness of design.
