My sister-in-law’s parents have three separate kitchens. Milchiks and Fleishiks are in separate rooms, and there is a separate section with its own sink for Pareve. It’s interesting because they are Mesorati/dati-lite.
Her father is very proud of it and made a point of showing it to me when I was there for a simcha. Maybe he wanted to make sure I would eat by them.
