Tim and I visited the house site on Saturday afternoon, and were pleased to see that they had finished putting down paper on the roof (although they had not finished putting on shingles). Most significantly, they had completed all of the electrical wiring in the house!
Shingles were about halfway completed on the back side of the house only.

They also had ducts in place…
Tim has the day off today, and called at lunch to say he did a drive-by and witnessed the workers finishing up the shingles. I’ll go by to take more pictures Wednesday or so…
