Good design is proper ALLOCATION OF SPACE.

If you are in a standard quarter acre lot, with setbacks, and height restrictions… you will eventually buck up against a size issue. Limits… and suddenly, you are pulling in walls and halls, in a subtractive nature, not additive… you are making a bedroom smaller, to give proper walking room to your closet, you are subtracting room from bedroom for the adjacent bathroom.  This is a constant ..down to the inch compromise.

Instead of a massive living room or bedroom, carve off space for a pet room, cat room, laundry room, nursery quiet room.

Have a large enough closet, with 4 feet of space to walk, have large enough rooms, with good flow. It is a constant re allocation of space…. again, this does NOT cost more, it is just thoughtful, correct.

Finally, make sure your doors open in the right directions… My worst conflict is my dryer door conflicting laundry room door, so I have to do a constant dossy do, EACH time I take my clothes out…. AND make sure the laundry room door is at least 36 inches wide, to carry your laundry basket out, without twisting sideways thru the door.
