Here’s the lower level before demo started.
Posts under ‘2. Demo + Structure’
Our church house was constructed with a rubble-stone foundation. That means basically that the builder dug a deep hole in the ground and then started constructing thick stone walls to form the perimeter of the structure. The walls are about 24 inches thick at the base. They seem to extend 2-4′ below the level of the lower-level floor, which is between 10′ and 6′ below grade depending on where one is on the slope of the site.
As the walls extend upward they become thinner. At the top of the building they are about 12-14″ thick. When the walls emerge from the grade, the outer face is nicely dressed and pointed, whereas the inside face remains pretty rough.
