Here's the funny thing about kitchens. I've seen a lot of fantastic kitchens in homes of people who cook, and they're always classic. What I find funny are the suburbanites who take out mortages to make their kitchens look nice, when all they prepare is some out of the box mac n' cheese and maybe open a can of tuna. This whole kitchen craze has always been funny to me.
I've gotten to see a lot of older manors in England, France and Italy, and quite a lot of important homes in NYC and Greenwhich, CT. Funny enough, a lot of them, before this kitchen craze, had very very basic kitchens. In fact, in many of the really serious homes where the people don't cook themselves, you're likely to see mostly butcher block and a large industrial fridge and an old range, along with some very basic terracotta or other utilitarian tile.
I'll never be worried about a white cabinet, carrera marble, stainless appliance kitchen. That will never go out of style, ever. It works, it's beautiful, and it will always sell.
