An element everyone would like to add to their Kitchen Design is an island or a peninsula for seating. Ridding the Kitchen of the old table and getting people up close and personal to what is going on is a growing trend.

Tip #2: The 3' Rule This one is way simpler. Keep at least 3 feet between the wall and your island or peninsula for a walkway
