With the building now more enclosed, we were able to begin interior work, specifically in the areas of plumbing, electrical, and mechanical. Marcus and JD from Innovative Plumbing came back to help us extend the plumbing in our foundation up into the walls and out of the roof for venting. We also had Rey from K-Bar Electric come and get our electrical started, taking us on as temporary apprentices to teach us the world of electrical. Jörg tackled installing the ERV which looks like a cool spaceship hanging from the ceiling. The help of these professionals has been fantastic, teaching us so much and advancing our progress leaps and bounds.
