When is an Island not an island? When it’s a peninsula. If you want an island but just don’t have the space or the shape of a room does not lend its self to an island, because for example, it's long and narrow. A peninsular is probably the answer. Like an Island, it creates important extra space, a place to congregate with family and friends and a focal point.
By attaching the peninsular to a perpendicular wall rather than a row of units and putting no units on one side or above, it appears to float like an Island and creates a very open feel while defining the separate zones in your kitchen living space without the need for a wall. A peninsular also allows the available light to flood the whole space. Access can be from three sides rather than four or more created with an island. However, a modern peninsular is so much more than just a breakfast bar.
