So inspiring! The kitchen layout is very similar to the kitchen of the house we will be moving into. I love the finishing touch from the top of the cupboards to the ceiling. I have a feeling that our ceilings are lower than what I see in your design. If so, would you recommend omitting the finishing crown moulding and just have cupboard to ceiling?

Those ceilings are 102" and I have used 2 pieces of trim: a flat board + a crown molding. No matter the ceiling height, I would not recommend cabinets touching the ceiling for the following reasons: it would be difficult to open the doors (they'd scrape the ceiling) and ceilings are typically not 100% level so you need the flexibility of the molding to handle the leveling issue. So install a shorter wall cabinet and leave at least 3" above the cabinet for some kind of trim. It could be one layer of flat stock -- doesn't have to be a cove or crown molding. Your cabinet company should have a few options for you.
