When space and budget allow, then a large kitchen island can be an ideal addition to any kitchen area. Whether you're looking for extra seating, storage or room for food preparation, a large kitchen island can be useful in helping bring all three elements to one convenient space.
Once you have determined how you will be using your large kitchen island, you can begin to choose the design elements that are important to the function of your kitchen. If you are looking to add more room for dining, then be sure to choose a kitchen island that allows for stools and adequate leg room.
A large kitchen island can also accommodate an additional sink or cooktop. These features can be especially helpful to people who prepare the majority of their meals at home. If cooking is a priority for your large kitchen island, then you might also want to consider a wooden surface for chopping or stainless steel countertop for easy cleanup.
And remember the fine china and wine glasses you own, but only get used once a year? Glass front cabinets with overhead lighting can be the perfect spot to store these items in lieu of a traditional china cabinet.
Be sure to look at examples of large kitchen islands in order to have a better idea of what you want from your addition. It might also be helpful to consult friends who have a design that is similar to what you are seeking.
