Each face of the house is clearly symmetrical, bespeaking the sense of balance which was so important to the 18th century. The end walls are in Flemish bond; the walls of the basement are of stone, the individual stones being like huge pebbles, rounded by centuries of washing on some beach. Such stones in colonial homes are often called “ballast stones” because sometimes they were shipped over as ballast in vessels from England and other shores. However, there is some doubt that this was so in the case of the present house, because it is unlikely that a ship in ballast could have sailed into the shallow Pasquotank River. The floor plan and the famous interiors of this house will be discussed later in this booklet. To be noted along with brick houses are a few stone houses in the Piedmont, remaining from late colonial and early republican times. Figure 36, the Michael Braun house, near Salisbury, built between 1758 and 1766, is an impressive example. Its orange-hued walls are two feet thick. Some years ago the house was in poor condition, remove this phrase, but was repaired by the Brown (Braun) family. It has now been purchased by the Rowan Museum, Salisbury, and is being restored by that organization. [Illustration: FIGURE 36. MICHAEL BROWN HOUSE, NEAR SALISBURY.] Like so many of our early houses, the Braun house is unusual in several ways. Immediately striking is the non-symmetrical division of the stone façade, not at all like the Old Brick House and other 18th-century houses. The wooden structure at the right is the kitchen. In the kitchen is a great fireplace along the stone wall of the house, with the chimney containing ingenious flues to heat adjacent rooms in the house. The kitchen is a restoration. ROOF IDEAS—GABLE, GAMBREL, AND HIPPED In discussing the structure of colonial homes we add a note on the several kinds of roofs which were used. After a builder had raised the masonry or wood walls of his house, the roof was a major design and construction problem. The type of roof selected represented what the builder thought was good-looking and appropriate for his special needs. Our diagram, figure 37, shows a _gable_ roof on the left, contrasted with a _gambrel_ roof on the right, each type having a dormer window to light the attic space thus making it more pleasant and usable. The gable roof is simpler in construction, and was the type most generally used in the colonies; but our diagram suggests how it cramps free movement within the attic. The gambrel roof, although calling for more involved construction, affords more head room. Apart from the space consideration, the gambrel roof is rather cheerful and attractive when seen from the outside, a factor that may have been responsible for the 18th-century fad for them.
