@Sturgis,
I use my kitchen daily too Sturgis. I wasn't meaning that anyone should get rid of them altogether. More that they could be put back into it's proper priority as far as it's importance.
Homes going to an open floor plan (which I despise) didn't have anything to do with kitchens becoming more or less important.
I believe it was truly a thing we were "told" we wanted by builders who were wanting to cut costs by leaving out a wall or 2.
Just as people are told what fashions they are supposed to want from year to year, by providing only what the fashion industry wants us to buy.
I worked some temp jobs as a new home hostess for awhile, on weekends. There was one house I went to often. The builder of the community would come in and out, as various marketing materials were kept there, among other things he needed. We were talking one day, and he asked me my opinion on the homes he was building, in general. I told him a few of the features I liked, but also said I really didn't like that all the new homes being built were the open floor plan, and I thought the kitchen should be a separate room. I said if I bought that house the first thing I'd do was put up a wall , even a half wall, at a particular area, to separate out the kitchen from the living room. He pointed out to me a weight bearing column and said that's where the wall would go. It was then I realized, and blurted out, that this open plan was because it saved them quite a bit in building expense, didn't it? He looked taken aback for a second, then kinda chagrined way saying something like "Well, yeah, you could say that."
Unless you have OCD, that model home perfect kitchen that can be seen from all over the house is at some point, or often, going to have dishes in the sink, open cereal boxes and other stuff all over the counter, not to mention cooking odors, and grease from cooking spreading more easily all over the house, rather than being much more contained in a smaller area. People spend a lot of money to make the room(s) next to the kitchen look all designer and sophisticated, then ruin the effect by making themselves and everyone that comes in the house stare at what is essentially a work area, messes, and refrigerator art.
Full kitchens with all the bells and whistles became popular not because people where asking for them. It was because the kitchen is a real money maker for builders. It's the room with all the appliances, expensive countertops, with the added attraction of it all sitting right out in the open.
No other room in your typical home has as much money tied up in it, by a long shot.
That expensive room with no walls is like the fantasy of a wedding. Neither were common until relatively recently. People have been sold this idea that they will constantly be in the kitchen, cooking paella and quaffing wine while wearing a designer caftan, while laughing and bonding and **** with their guests. Like they couldn't not be in their company for the time it took to get the meal out, and like everyone is going to enjoy watching the cook, and standing around. Ditto with the fantasy these kitchens someone equals family. It's all marketing.
Not saying a kitchen....actually I suppose kitchen area is more what I'm meaning, should be dark, dank and secluded. Not saying for some the room gives them great joy.
It's just not, in general a very cost effective room, when one looks at the amount of time working in it. For many people, having a kitchen area seems much more practical overall.
Personally, I use my microwave for heating leftovers up. That's about it.
I do cook breakfast, because I'm not about to leave the house before coffee and all that.
I'll cook dinners, but augmented with things that have already been prepared, even if that's just bagged salad.
On my stove, there is one burner I use 90% of the time. Sometimes I use a 2nd one at the same time.
As far as costs, when I look at the price of the things I buy to prepare at home, it just isn't significantly different per meal than if I had just bought it prepared or quasi prepared (I think I buy more quasi prepared stuff).
The other day, Wally wanted soup. He loves this soup I get from the hot soup bar at this local market. It's I think 7.99 a quart. I said "how about if I make it instead? He said fine.
I added it up after I made it, and between the broth, veg, noodle and meat, the quart of soup I made cost right around 6.99. Not to mention my time, the cooking gas, and clean up.
I know a lot of people eat badly, and they eat out a lot.
Geographically it might not be practical to go out to buy meals.
All kinds of other stuff too.
When you think about it though, I think a lot of people would do just as well with the basics tucked away in a corner. Maybe part of the reason we're so fat is we're got these big kitchens staring us in the face.
