Interesting idea for kitchen and dining room. Island with a bench seat attached for the table. Might have to do something similar in my new place to save room for chairs. Under the bench seat could be storage for rarely used items.
Sliding barn doors to hide laundry area; slide out of the way to be completely unobtrusive when you need to work within the space I don't much care for the barn look but the slide door is cool even a pocket door would be a good idea
