Thanks to Grrrowler/David for their comments...this is the "updated" family kitchen.
I really appreciate that a sink/dishwasher across from the double range/oven could be a conflict. As a result, I have placed a prep sink in close proximity to the double refrigerator and the double-range/oven, but now positioned at the end of the island (out of the way of kitchen traffic). Adjacent to the prep sink is a trash compactor and ice-maker. This leaves the bulk of the central island unobstructed for meal preparation and baking.
I have moved the dish sink to the 'other island' (the "eating island") and have added two dishwashers adjacent to the sink.
I have also decided to add a built-in-microwave oven to the left of the wet bar, as well as an espresso machine. I have decided to keep the wet-bar as is (with some modification from the previous sketch), and have added space for wine bottle storage. On the central island I have also placed ample space for plate storage, but the breakfast room will be surrounded by cabinets for china.
There will be a catering kitchen, on the lower level, with access to the butler's pantry, which connects the family area (kitchen, family room, breakfast room) to the main (formal) dining room. There will be a staircase leading to the catering kitchen, as well as a dumbwaiter which will allow easy passage of food to the formal dining room.
Please check back soon for updates! Thank you for all of your architectural expertise and comments. It is extremely useful! Please continue to provide feedback.
Once I have completed the ceiling detail for the family kitchen, I will begin to provide renderings of the family kitchen.
