Two-Thirds I House
Two-thirds of an I house or one-half of an I house, depending upon the importance assigned the hallways, this 2- or 2 1/2-story structure is one room deep with a hallway and a single room on each floor. Like I houses (see above), these structures were commonly enlarged with rear L or T extensions. The form was introduced in the eighteenth century, remaining popular throughout the nineteenth. For two-thirds I house, see Glassie 1968a, 67; for one-halfl house, see Montell and Morse 1976, 40. (Jakle, 1989)
