This image of the same space as a few posts ago, Shows the Northern exterior of the first building campaign. The plaster that remains is from the lean-to addition. How this wall reads is that the lean-to addition was only used on the main floor because of the lack of plaster surface above first floor. The rafters for the lean-to started approximately two feet above plate and landing on the other rafter. An early roof still exist on the main portion of the house.
