The choices don’t seem particularly shocking to me, so I don’t understand why they seem so obviously bad to you. For placement of bedrooms, I think the question is where else to put them. I guess they could have the office/4th bedroom next to the master instead but what the rooms for is obviously somewhat subject to change. For the bathing part of a bathroom being near bedrooms seems logical. There appears to be a small lavatory off the kitchen area but maybe it isn’t ideal not having a proper lavatory connected to the living space, especially if they actually do as much entertaining as they planned when designing it. I don’t know how to square your statement about architects seeing dumb money with the fact that many things you suggest they do would be more expensive and therefore increase the architects fees.
I don’t understand the comment about how fast your car charges at all. I suspect that electrical heating in the winter is the main thing that would push up power usage (especially with double-height rooms) but I’ve no idea really.
