A friend has a new home with no bathroom door in the master bedroom.
We were in the house a number of times while it was being built and after. DW was shocked!
I noted that while the sinks are fully in view from the bedroom, neither the shower, bathtub nor toilet was. In fact, with the tub, you have to enter the room then turn around to see it. Only the shower and tub have a view of each other. Oddly configured room, odd corners ... too much bother went into that design

.
The entire house is like that - too many odd corners, lost space, it's hard to clean. The owner came to seriously dislike some things. She's spent a fair amount of money making changes in a home that is only now about 10 years old. An attractive exterior but everyone comes in the backdoor, functional.
I'm inspired by simplicity. And, have to guard against giving up beauty to function. These interior designers who can turn old industrial area warehouses into lovely apartments dazzle me with their creativity. A bare naked room becomes beautiful ... and functional. Trivial little nothings aren't enough.
One thing that they are doing in some designs is providing the essentials of the home as a unit. The essentials of a modern home revolve around electrical, water, heating/cooling, cooking, bathing, privacy.
