As the chief cook and bottle washer for our family, I'm going to feel free to jump in here.
With Sorcha, LOTS of counter space, including a good sized space at a level where I can sit and do food prep (slicing, peeling, dicing, etc.). Currently, I have to move everything to the kitchen table, making sure to put down newspaper or the like to catch the spills and debris. I also agree on the four vs. six burner stove although I'd like one of the small portable burners for countertop use when needed. Also lots of fridge space.
We replaced our kitchen countertops last year and, in the process replaced our stainless double sink with one molded into the countertop. While we were at it, I chose a double sink with one large deep sink (16" wide, 13" deep) and one shallow small one (7" wide. 6" deep). This arrangement has worked well for me. For our new sink's faucet, we chose one with a high arching spout so I can maneuver a large pot under the faucet for filling. The last few inches of the faucet also act as a built-in sprinkler which pulls out of the main faucet and provides the ability to aim the water flow - by pushing a slider button on the side I can have either a solid or sprinkler flow.
We're thinking when we return home for the summer we'll install the metal pullout trays for our pots & pans cupboard so I don't have to stand on my head to get something from the back of the bottom shelf.
When I was younger, I had much bigger dreams for my ideal kitchen, but, at the age of almost 68 (in two weeks), I know who's going to have to clean all those lovely appurtenances, so my dreams have become more realistic.
