No after pics, wonder what was chosen or if decisions are still being made. I personally loved the off white tile, but you could go with a travertine or marble flooring, throughout for a clean, cohesive look. Another option is FLOR, carpet squares. They are not only very modern, but great with pets, you can clean or replace one square at a time and re-arrange them into different patterns as well, depending upon what you get. Looks like the home is painted white/light so going dark on the floors would work. Reclaimed hardwoods would look nice, and old like the home, as well. Many MCMs had hardwood or Terrazzo flooring.
