If your kitchen island is not as large or functional as you would like, you save the cost of buying a new one by expanding the one you have. You can gain new counter space as well as fitting it with new storage cabinets or even an extra sink or stovetop.
Determine the Location of Expansion
When adding a new kitchen island expansion to your kitchen, you must first determine if you have enough room. Islands can take up more room than you expect. Measure the area around your kitchen island to determine the best location for it. For example, if you are adding a small seating area, the rear of the kitchen island would be a better alternative than the side.
Mark out the new expansion on the floor with masking tape and leave it there for a few days to see how it affects foot traffic. If there isn't adequate room to maneuver around it, your new island may turn out to be more hindrance than help.
Remove Floor Covering
To construct a more uniform expansion you will need to remove the current floor covering from the area you are going to use. If the floor is vinyl, you can simply cut it out with a utility knife to conform to the shape of the kitchen island. If your floor covering is tile, you will need to remove each tile separately, and remove all grout and mortar.
Build Frame for Expansion
You can do this either off-site or build it onto the kitchen island. Measure the 2x4 lumber to fit your desired length, height, and width. This is going to be determined by the amount of space you have in your kitchen. Remember to leave at least 2 inches for the countertop when measuring for your height. Build the frame with wood screws and seal each screw with caulking to keep them from rusting or loosening.
Once the frame is completed, you can add the countertop. For a basic eating area, a tile or Formica countertop will be the easiest to install. Simply cut a piece of ½-inch plywood to size and screw it to the frame. Apply the mortar, or adhesive, and lay the countertop down.
Attach Outer Covering
To finish off the kitchen island expansion you can wrap the island with pine tongue and groove planks. This will add a great country look to your island and is easily installed with finish nails.
Add the kickplate to the bottom of the kitchen island to protect it from being kicked by feet, or marked up from a mop or vacuum. Finish the flooring around the island and clean the countertop.
