Islands and peninsulas are generally added to kitchen layouts to provide better organization of the space or to make the work space more functional. Islands are frequently added to other basic layout shapes to provide additional work space or storage (or both). They can also serve to keep guests and children out of the work area during food preparation. Peninsulas will almost always add counter space and storage space to a standard layout. One advantage of peninsulas is that they organize the space and offer storage that is accessible from both inside and outside the work area. With a large amount of traffic to the kitchen for drinks and snacks, they offer the perfect place for a small refrigerator. This saves energy (by not opening the main refrigerator as often) and keeps children and guests out of the work area. Islands and peninsulas can also be used to provide informal dining areas.
