Looks awesome! Out of curiousity, how do you plan to manaage the cold garage under the living space? Will you heat the garage too or insulate the floor?

We're going to have the floor trusses (18" deep) blown full of insulation after the plumbing heat/cold-air-runs and electrical are finished. I need to drywall the ceiling of the garage and leave a 4-foot section of drywall out down the center of the ceiling. This is so the insulating company can blow it in both ways. They then net and fill the void before I finishing hanging the drywall.
