Gunston Hall can be divided into three major sections: the formal rooms, the family rooms, and the upstairs bed chambers. The formal rooms are made up of the dining room and the great parlor. Each of these is decorated lavishly and must have made quite an impression on the Masons’ guests. The little parlor and main bed chamber served as busy family spaces. The hallways, or passages, are intermediary spaces. The service stairs provided an out-of-sight way for enslaved and indentured people to move from one level to another as they carried out their duties.
