Four burners in a row along the counter so that I would not have to reach over one hot pot to check another (I am altitudinally challenged).

One of those marvelous countertop indoor grilling surfaces, with the requisite venting of course.

A pot-filler tap (or simply a spray nozzle on a pull-out hose) next to the cooktop to so that heavy pots needn't be carried across the room.

Enough, intelligently designed pantry space (no deep, cavernous cabinets need apply)

Enough, intelligently designed food storage space (no deep, cavernous cabinets here either)

Enough light

No white anything (too much glare)

I also joke to my husband about building our new kitchen floor on hydraulic lifters so I can reach the upper cabinets and so both of us can have the work surfaces at comfortable heights when we need them...

...which reminds me, if you are designing your own kitchen, remember that building all the countertops and workspaces to exactly the same height is just like buying one-size-fits-all tights: it's convenient for the manufactor, but not for you. I like to roll out pie crust and knead bread, for example, on a surface that's six inches lower than the one I'd use to carve meat or chop vegetables.

A huge sink, maybe even two sinks, but NOT a double sink. I hate not being able to get my larger pots into the sink, or not being able to lay a bouquet of roses in the sink while I trim the stems underwater, assuming I ever get roses again...
