The Ranch House originated in the 1930's designs of Southern California architect Cliff May, who sought to reinvent the west's vernacular housing traditions by combining the form and massing of the traditional ranch house with a modernist's concern for informality, expressed in materials and plan, and indoor-outdoor integration. While the style includes several variants, a basic set ofcharacter-defining features applies to most examples. In form and massing, the style evokes a sprawling ranch that developed over time, with a central block extended by wings of varying roof heights. Generally L-shaped or U-shaped in plan, the Ranch House typically has aone-story profile with strong horizontal emphasis expressed through a low pitched or flat roof with wide overhanging eaves. Asymmetrical in design, the Ranch House is often sheathed in and accented with rustic materials such as board-and-batten siding, high brick foundations, art stone, and wood shake roofs. Indoor-outdoor integration is achieved through the use of recessed or extended porches, set low to the ground, and the generous use of large picture, ribbon, or corner windows. Window detailing can include wood frames, decorative shutters, and diamond-patterned muntins. Ornamentation includes rusticated elements, such as carved porch supports and exposed rafters, uneven rakes and flared eaves, and faux dove cotes and bird houses. The Colonial Revival Variant of the Ranch House incorporates classic-revival details such as an elaborated entrance, with the main entry flanked by columns and/or pilasters and sidelights, six-over-six double-hung wood sash windows, and a more symmetrical composition than the other stylistic variations of the Ranch House. SUMMARY/CONCLUSION: As a contributor to the North Broadway Park district, which has been determined eligible for listing in the National Register of Historic Places, the Rohrbacher House has been listed in the California Register of Historical Resources.
