The three parts of the Federal Reserve System are the Reserve Banks, the Federal Open Market Committee (FOMC), and the: ABoard of Governors BUnited States Mint CDepartment of the Treasury DSecretary of State.
The standard overhang of an island countertop -- on the side designed to sit at and tuck stools underneath -- is 12 inches. If you plan to extend the counter farther, you need to add supports such as legs, or wood corbels or metal L-brackets that extend half the overhangâs distance.
I'd allow 24 inches per, so people can enjoy breakfast without banging elbows. A popular arrangement is to have seating on one side and both ends, if space allows. The overhang should be minimum 12 inches, 15 is better. Plan to allow 36 - 42 inches between the island and the nearby kitchen countertop. You want people to be able to safely pass (while carrying very hot items).
