There are some really intriguing things happening in your floor plans. What are you trying to optimize? "Optimizing the design" is a very broad statement. Side note, the bathrooms on the center floor are going to feel incredibly small and should be just a shared bathroom or hall access bath. Good luck with your project!

Um, seems like lots places to sit and not much closet space?

Is this in the U.S.?

Optimizing a gallery kitchen- 30" deep counter and I'd go to a single sink and induction cooktop like a Miele or Bosch Benchmark or 800. If a slide-in range a Bosch Benchmark/800. Frig and freezer columns.

Lynn, looks like lots of closet space to me, especially in the master. All the space is usable as it is reach in rather than losing space in a WIC.
