This week, Colin started wiring for the new bathroom as well as rewiring what was the kitchen and the living room. Chris also ripped up the old floor so that the plumber (Shawn) can run the pipes. In the photo below, the joists under the plywood run perpendicular to the wall. There appears to have been a staircase at some point (fifty years ago or more). Very curious as to what the layout of this house has been over time.
No sign of any bats in the attic today.
