Oooooh, what fun! We took our 1901 fixer-upper down to the studs and started rehabbing it ten years ago (work still continues to this day), so I had the fun of designing my dream kitchen.
Things I got right:
For the floor I used the same rugged linoleum tiles they used in my daughter's high-school cafeteria, in a splotchy speckled pattern, dark and light on battleship grey. You could slaughter a cow in my kitchen and the floor would look none the worse for it.
Gas stovetop, two electric ovens, one topfit for broiling, the other convection for baking and roasting.
No dishwasher. I collect pottery, so have to wash most of my dishes by hand anyway.
No garbage dispose-all. It took a while for the composting folks in the City of Seattle to catch up with my concept, but Seattle now composts all food materials including animal bones and fat and soiled paper products (like pizza boxes). Having no garbage-eating appliance in my kitchen made me very forceful as an advocate for city composting.
I kept my old cutting table, an inexpensive 3'x5' wood table that I have been cutting on for 25 years. The first year, 25 years ago, it looked pretty grotty, but by now it's beautifully distressed and a memory bank for all our kitchens past. I warmly recommend a cutting table rather than a cutting board -- room to spread out. We also eat some meals there.
A big peninsula with open shelves up to counter height on both sides and then pass-through shelves above the counter. I keep all our ordinary everyday dishes on the pass-through part, so I can get help setting the table without having somebody elbowing me on my side of the peninsula.
On the other side of the peninsula, there's a separate area for my husband's cooking tasks, which include whizzing up veggie smoothies in the morning, making coffee, and making his lunch on work days. We can both work in the kitchen without getting in each other's way. He has his own small sink there, although he still does impinge on my big double sink on my side of the peninsula, I don't know why.
I painted each of the four walls a slightly different color, dark yellow mustardy and turmeric colors, because I knew I was going to spend more time in the kitchen than in any other room in the house and I wanted my view to stay lively. The painters told me I was crazy, and maybe somebody else might not like it, but I love it.
A forgiving surface for countertops, two of them wood, the third formica. I had a hard countertop surface, tile, in a house I lived in many years ago, and I'm just not careful enough to use a hard surface like that well. I broke dozens of glasses and plates and abused all my knives inadvertently. Never again. I wonder that people like granite countertops -- they must be much more careful than I am.
I just a couple of months ago got one of those thick gel mats to stand on while I'm doing the dishes, and I wonder what took me so long, my feet and legs love it.
Things I got wrong:
I didn't analyze the traffic patterns carefully enough, and there's one particular pathway, from the open part of the kitchen, past the cutting table, to my husband's side of the peninsula that's 2-3 inches too small when somebody's sitting at the cutting table. If I had thought it out better, the peninsula could be just a smidgen shorter and we wouldn't experience that particular bottleneck and bang into each other. Figuring out your working patterns and traffic paths is by far the most important part of the design.
Um, I'm kind of embarrassed to mention this, but I didn't test out my stove fully while it was under warranty, and I got some Cadillac features that haven't proved worthwhile. The wok burner is powerful, but because it's only a ring with no central flame it doesn't do a good job of heating the wok evenly. My nice little carbon steel wok I got in China has a usage ring where the flames hit the pan. And having two ovens is fabulous, I love it, but I can't have both on full blast or the stove blows a gasket, one or both ovens turn off, and I have to wrestle the stove away from the wall so I can hit the Reset button.
Things I'm still working on:
For many years we had a guest room, principally for our mothers, but both of them are past their visiting years now, so I'm converting the guest room to a pantry. It was quite a small guest room, but it's huge for a pantry. Oh joy!
