A garrison is style of house, typically two stories with the second-story overhanging in the front. The traditional ornamentation is four carved drops (pineapple or acorn shape) below the overhang. Garrisons usually have an exterior chimney at the end. Older versions have casement windows with small panes of glass, while later versions have double-hung windows. The second-story windows often are smaller than those on the first floor. Dormers often break through the cornice line.
