That's a really nice model but I said I was downsizing not upsizing.
There are about 250 people in the town and 600 (or so) in the municipality. So the building and zoning department is really small. Only one person works in the municipality office and I have been hunting with both her husband and their son. If they have a building inspector I probably have had a drink with him at one time or another. It's all about liability. As long as the plans have a engineers stamp on them I'm good to go. As long as your paying cash you don't really have anyone looking over your shoulder.
This is what I'm sort of looking to build:
The changes I want to make are increase the footprint to 28' (or 30') X 38', swap the bedroom across from the bathroom with the bathroom and move the kitchen across to the same side. This puts the wet wall all on the same wall. Delete the side entrance. Increase the master bedroom and the bathroom sizes.
