Mind Your Head : If you are hanging anything from the ceiling, make sure that there is sufficient clearance so that people do not bang their heads on a skillet or frying pan! Clearance is all-important with kitchen islands, because there is not a lot worse than having a kitchen that is severely restricted in space just to accommodate an island. The island should complement your kitchen, not dominate it.
One of the biggest pluses about kitchen islands is that most of them contain extra storage space for all of the paraphernalia that is so necessary in a kitchen today. A kitchen island cabinet can be just the solution to the problem of "Where am I going to put that?"
Include a ventilation hood overhead to eliminate smoke, steam and cooking odors if your kitchen island is going to have a cooktop. The range hood should extend beyond the cooking area by 3 inches or more on the sides for proper ventilation. Using the correct fan size will ensure that removal happens as intended. Have a fan capacity of about 50 cubic feet per minute (cfm) for each square foot of cooktop area.
Allow adequate countertop space on both sides (left and right) of the kitchen island if a sink or cooktop will be used. Include at least 15 inches of countertop space on each side, and if your kitchen is large enough, allow even more space. You can never have too much countertop space in a kitchen. Also, rounded countertop corners help protect everyone from bad bruises -- this is true about all kitchen countertop corners.
