Nice!
I used to build high end homes in a previous life. My older brother and I, along with two other tradesmen, worked pretty much exclusively for a handful of GCs out west, and typically built the homes from the foundation up. The GC might hire out the electrical at times depending how involved the framing and detail work was.
What was nice about that was, we got to hang the (20 year drywall man) sheetrock, tile and trim/cabinetry etc. over our own framing. The GCs figured out rather quickly how much they were saving on punch lists and lack of delay and associated fees. The fact that all of us were reared in the piecework realm, we got things done with little waste in time/materials and could afford to do things perfectly.
