Maybe I should ask a different question: In this plan I am attempting to show the brick ledge extending below the lowest floor level. As the front of the house is elevated for steps up to porch area and the rear porch is16" lower as it steps out of the sunken living room. I have been playing around with the stem wall trying to make this happen so that in my elevation views the brick exterior will extend below the floor level in order to cover the areas not covered by the terrain. I hope I have made sense here. I think maybe there is a better way to do this than what I have done.
