I know what you mean with the errands - family seem to save up time consuming BS for when we visit. My wife is the eldest and the father has now passed away, so she is 'head of the family'.
Don't know if was said up thread, but for me a nice outdoor space is more important than the inside of the house. Especially in the evenings. Inside is more a place to sleep, and take refuge from the hottest part of the day.
But anyway that's me - look forward to seeing your next design.
