Cape Cod House Plans: Cape Cod homes cropped up on the eastern seaboard between 1710 and 1850. Abundant timber resources encouraged the expansion of these traditional, one-room English cottages and marked them forever as the quintessential New England style. Cape Cod house plans are simple and symmetrical, usually one-and-a-half story house plans, and often incorporate dormer windows for an even warmer touch. Cape cod house plans also tend to have dominant rooflines that extend down to the first floor ceiling level.
