The two room plan houses in figures 25 and 26 were expanded as the space requirements of the occupants increased. The first example has a rear appendage. Vertical board and batten siding was used on the addition, but an inconsistency in window sash selection occurred. In figure 26 the appendage was built as a shed addition on the side. This large two room house is two rooms in depth. This additional depth allows the roof to be higher, a definite advantage for the reduction of summer heat. [Illustration: _Fig. 25. Two room house with board and batten siding (Bldg. 118)._] [Illustration: _Fig. 26. Circa 1910 two room house on the O.Z.O. Plantation (Bldg. 129)._] The shotgun type house plan, figure 27, was used abundantly on the river plantations. The typical plan was one room wide and two or more rooms deep. There were front and rear gables. Variety occurred at the front gallery as evidenced in the pair of shotguns illustrated. The gallery might be the full width of the core allowing space for chairs and thus creating an extra “room” for relief from the summer heat of the interior rooms. This gallery also provided a place for social interaction between the occupants and passersby. In contrast with this situation, the porch on the right was of the width necessary only to protect the door from the elements and to provide shelter for those entering. As shown, shotgun houses were often in close proximity to each other. This feature may have had its background in the fact that the shotgun plan had been used in urban situations in New Orleans where property was extremely valuable. However, when the plan was transported to a rural situation, the close proximity characteristic remained. [Illustration: _Fig. 27. A pair of 1920’s shotgun houses (Bldg. 125)._] THE 20TH CENTURY FARM BUNGALOW HOUSE As the 20th century advanced so did the plans and techniques of constructing the folk house. The bungalow plan was introduced into North Louisiana circa 1915. This plan type was two rooms wide and two or more rooms deep with front and rear gables. The bungalow plan would continue to be a popular house type in the region until the advent of the ranch type plan after World War II. The dwelling pictured in figure 28 was typical of the bungalow of the 1920’s. As previously mentioned in reference to the shotgun house, the type of bungalow front gallery varied. The contrast may be observed in figures 28 and 29—the nearly full width gallery with hipped roof and the half porch with gable roof. An almost universal feature of the bungalow house was the use of exposed rafter ends. [Illustration: _Fig. 28. A 1933 bungalow plan with hipped gallery (Bldg. 123)._] [Illustration: _Fig. 29.
