In addition to seating 4 (or more), islands today are used to house "luxury" appliances that do not fit in the cabinet structure like a second microwave, second oven, wine refrigerator or even another cooktop. Islands many times are fully wired for electricity and have plumbing for a second sink. The base of an island can be used as a wine rack. The possibilities are almost endless.
Why do this, since even stock plans cost you at least a couple of hundred dollars each? Because the right stock plans can save you tons of time and money if you have a talented architect. Most plans are at least partly modular these days, and often you can even order prefabricated sections pegged to a specific house plan.
The kitchen is the heart of the home and you want it to be a room that is welcoming and cozy for family and guests. But kitchens tend to be busy places and can get messy and cluttered up pretty quickly with all of the appliances and gadgets, not to mention décor items, which can diminish the nice atmospheric state you're going for. One good solution is to install a kitchen island. Not only are they convenient as a means of additional workspace, but many are equipped with their own cabinets and drawers to help you prevent that untidy appearance.
For those remodeling and looking for an "open" feel where perhaps the wall or half wall separating the kitchen and the dining room is taken down, a strategically placed island acts as a subtle room divider mentally separating the kitchen from the dining room but with a much more open feel.
