The Blair House evolved in a manner much like Wetherburn's Tavern, illustrating how close domestic and hostelry forms were in the eighteenth-century Chesapeake. This house began early in the century with two rooms flanking a stair passage, much like the BrushEverard and Tucker houses. Around mid-century a superior entertaining room was added to the west (left), with independent outside access. Improvements in finish also transformed the house, from a building entirely covered with short, split clapboards to its present refined appearance, with shingles, planed weatherboards, and classically inspired moldings.
