Front right-hand corner: I haven't been down lately so all I have to go for now is the pictures the builder sends. Looks like he's feeding PVC into the corner. Not sure if that's for electric or plumbing or both. Also, you can see where they're using boards to form the concrete. Looks like a lot of work!
