Insulation on the outside walls.
The line that's furthest to the left is the bathroom fan vent.
They will have to cut a hole through to the outside of the house to complete this.
On Thursday, these small holes will be connected and and a large hole dug out for the toilet composter. Putting a bathroom in a basement isn't easy.
Thankfully, I slept through all the noise. My fibromyalgia is acting up because of not getting enough sleep. I am more exhausted than usual, in a lot of pain, and feel like I have the flu. It'll be nice when this project is finished and our house is ours once again!
