Going to be stick built as the say here. I'm calling it a man house, it'll fit quite a few "caves " inside. Finding a builder out here is tough as they all seem to be busy.
At least it's progressing, got the area for a pad cleared and a driveway rough graded to it. Our lot is full of trees and it took them two days get back where the building will be.

Going to put cold water in and a propane on demand boiler. I'm replacing the one in the house this year and use the old one for the garage.

Was going to put a full bathroom in but we would have to pump all waste uphill about 15 feet to the septic tank. Only about 75 feet behind the house so not too far to go.
