Well, dirt-bottom - Matt and Dylan and I worked hard today to get the majority of the plywood floors up from the basement, so we can assess what's going on with the foundation before we frame out the new rooms. Matt and Dylan took turns sawing up small pieces of flooring and jacking them up / banging them loose with a sledgehammer, and I hauled loads up to the landing and into a wheelbarrow and carted them out and tossed the pieces into the dumpster. I didn't last as long as these guys did, but as it is my arms are aching and I have a feeling I'll sleep like a baby again tonight.
Video highlights below, as well as on the main Videos page. We need to get Miles out in the next day or two for his opinion, and then set up the meeting with a structural engineer. We'll either pour concrete or dig out the dirt and reframe, or some combination of the two.
THANK YOU to Dylan, Craig, and Greg, without whom we'd be half as far along as we are. You guys rock!
