If you have some extra room in your kitchen, an island gives you an extra countertop, more storage space, a convenient seating area and the perfect place to socialize and entertain friends. You could even install a cooktop or range hood to increase your productivity when you’re cooking for the whole family. However, adding a kitchen island requires some careful planning. A blocky, oversized island could make your kitchen hard to navigate, while a small island without any features presents a missed opportunity.
