Salt Box—This New England Colonial style got its name because the sharply sloping gable roof that resembled the boxes used for storing salt. The step roofline often plunges from two and one-half stories in front to a single story in the rear. In Colonial times, the lower rear portion was often used as a partially enclosed shed, which was oriented north as a windbreak. These square or rectangular homestypically have a large central chimney and large, double-hung windows with shutters. Exterior walls are made of clapboard or shingles. In the South this style is known as a "cat's slide" and was a popular in the 1800s.
