A half-round, or demilune, console, as shown here, creates an interesting end to a built-in island and provides additional storage as well. Drury Design
Repurposed Buffets A rather plentiful item at antique stores is the vintage buffet. The 1960s versions are usually rather dowdy looking in their original wood finish, but give it a coat of paint and voilà — a whole new look. If you are going to paint it, you don’t need to find a pristine piece, either, meaning the price will be lower. Because furniture is rarely finished on the back, consider how you can finish this to fit both the piece and your kitchen, and whether you’ll need a carpenter’s help. ROM architecture studio
If you happen to own an interesting piece like this, not only will it make a statement, it will also provide good storage. In this kitchen, a cabinetmaker added storage onto the back, making it even more useful. Having a countertop made to follow the lines of the piece gives it an especially nice, custom look. Prices for buffets are all over the place. You might be able to find a small one for under $100, but the bigger, more ornate pieces can go for $700 and up.
