The island has a countertop length and width of 4 feet by 5 feet (about). This gives us an overhang on the far two sides of about 12 inches allowing us to create a breakfast bar. We wanted to keep it small though as our whole kitchen and house is very "tight" but still wanted the open feeling of a center island. The island helps bring together the kitchen, old dining room, and the living room.
To start with, we wanted an island that had storage on both sides. We selected two cabinets that were 12 inches deep with lots of shelves to hold things like fancy glasses and specialty cooking items. We butted these up to two cabinets that were the standard 24 inches deep facing into the kitchen. We built the IKEA cabinets.
To cover the sides, IKEA sold us two smaller appliance panels. Now the trouble with this was that they did not actually cover the whole side! Too short. We decided to use them on the side with the electrical plug as it would make it easier to put in the hole for the box. To make up for the two short, we used a T-mold for a matching floor to fit between the two pieces and make them the right length. You can kinda see it in the picture below. It looks a tiny bit different depending on the light.
3 inch handles for the cabinet doors. Here is a picture from Lowes.
