One chimney served two smaller rooms in the Ewing House. That and historical records that one of the east rooms was initially unfinished indicate that one room might have been a fabric workshop for Ewing, who was a merchant. When the house was restored by Colonial Williamsburg in 1940, a 20th-century porch was removed from the north facade, while the original framing was kept. Some of the interior woodwork, including the stairs, several doors and the flooring, survives from the 18th century.
