added lean-to

integral lean-to

In a colonial timber-framed house in America, a lean-to that was part of the original house construction, not a later addition or separate structure. This construction permitted the use of continuous rafters between the roof ridge and the eaves of the lean-to, thus providing a long, sloping roof of uniform pitch.
