The greatest number of extant Gable-Fronts (or Temple-Fronts) in the district were built between the 1890s and 1910s, although a few older examples date to the 1880s. A number of variations exist, such as the Gable Front & Wing and the Gable-Front & T Wing, the latter a local variant that builders from the Roaring Spring Planing Mill seemed to have favored in the 1900s. Most houses are balloon-frame construction, however, the Four-Square, built here in the greatest numbers between the 1900s and 1930s, is equally divided between wood and brick. Queen Annes range from the 1880s to 1910s, and are often really Four-Squares in form beneath a slightly more complicated roofline and decorated wall surface (ornamental slate or wood shingles) usually concentrated in the gables. The I- House, which ranges primarily between the 1850s and 1900s, is also equally divided between wood and brick. The center-door "Georgian" type (double-pile, side-gable roof, symmetrical massing) was built here between the 1850s and 1940s, with most examples ranging from four to five bays in width. After the Civil War, local builders often gave this type a large centered front gable, creating a Gothic Revival look, especially since most of these examples held full front porches with Gothic Revival trim. The Bungalow type, while not as common as the preceding four, was prevalent between the 1920s and 1930s.
