A very interesting question!
I would want a simpler smaller house. Kitchen (30%), Living/study room (30%), bedroom(15%), bathroom(5%). Mostly open common area (15%), utility room(5%). Single story. Plenty of bookshelves. Only enough closet/storage space to store the essentials (forcing me to get rid of stuff). Mostly glass walls facing a private backyard/garden. Skylights to bring in more natural light. Possibly movable/repartitionable interior walls so that I can reconfigure the space for variety or if there are guests. Situated near a nature park to go for walks.
A giant clock/calendar/display in every room to remind me what I am supposed to be doing (via color). Should show critical notifications as well. Lights that go on when dark but off at sleep time. Display on the main door that shows if I have everything I need to go out + reminders (given important things are tracked). Organized storage space with digital labels as to what goes where. “smart” house in the sense it reminds me of things based on room + time/date. Allow partial access to some of this to a coach (so that weekly/monthly/yearly reviews happen).
May be I can implement some of this in my present place!
