I've gutted and remodeled 2 kitchens so far. After doing the first one, which I loved so much, I was nervous that the new one would never work as well. It turned out even better. My space was kind of small, no room for and island or anything like that. I wanted 2 ovens and gave up lower cabinet space to have them.
One is a 6 burner dual fuel Thermidor, it's only 36", but the oven is massive. It will take a full sheet pan.
The other oven is a built in 30". I also have a pot filler - don't use it as much as I could, but forget it's there. I do appreciate it come canning time when using huge pots. Another thing I did because of limited space is get a full size refrigerator...no freezer compartment. I have a pantry in the laundry/mud room, just a few steps from the kitchen, and I have 2 large freezers in there. I added bay windows both above the sink, and in the dinette area. The one above the sink is great for plants, etc. and the one in the dinette doubles as part of the seating allowing us to push the table back from center and use the opposite wall for a mini fridge and bar sink that helps keep people out of the small kitchen area when entertaining.
Also, no microwave in the kitchen. That too is back in the pantry as it only gets used rarely. Left more overhead counters in kitchen area.
Last but not least, all under the upper cabinets has plug mould running full length. Never at a loss to find a plug in my kitchen, plus you don't have the receptacles ruining the look of the tile backsplash.
If you use your kitchen as hard as we do and have a wood floor, which we do, you'd better get used to the distressed look. You are going to dent and scrape it eventually.
Worst thing I did was let my lighting guy put in halogen undercounter light. I didn't want them, I wanted flourescent, but said he couldn't find any. (he didn't really try and I was impatient) Halogen are hot. A pain in the summer when you are trying to do pastry work. Fortunately, the kitchen is pretty bright without them.
