Some people have a different set of dishes for each party they give. Others buy paper plates. If you're cramped, decide if an extra cabinet or two will do the trick. Then measure cabinet spaces at all the models. Count the number of drawers.
Builders sometimes skimp on drawers to save money.
Look for adjustable shelves and Lazy Susans in corner cabinets. When you return from house hunting, compare the findings from each model kitchen with your current set-up. Don't overlook the pantry. Space grandma once needed to store canned fruit now is used to stock up on paper goods, pasta and gadgets. Add a microwave oven and sink, and no one will see the unexpected mess the children left when you blinked.
