The Gothic Revival was based on medieval English forms and fashionable in England before it appeared in America. The earliest of our Victorian domestic forms, identifying features of the style include steeply pitched roofs, usually with steep cross gables commonly decorated with ornate vergeboards; wall surfaces and windows that extend uninterrupted into the gables; one-story porches, and; Gothic-inspired window heads. Carpenter Gothic, a variation on the style, is applied to more vernacular types where Gothic elements are applied by craftsman.
