There's no hard and fast rule about where the kitchen should be located in a house. In fact, there are plenty of homes where the kitchen is smack in the middle of everything - and they work just fine!
The main thing to consider when deciding on the location of your kitchen is how it will flow with the rest of your home. If you have an open floor plan, then putting the kitchen in the middle might make sense so that it becomes the natural hub of activity. But if your home is more traditional and compartmentalized, then you might want to keep the kitchen off to one side so that it feels like a separate space.
Another thing to think about is how much light you want in your kitchen. If you put it in the middle of your house, then you might get lots of natural light from windows on all sides. But if privacy is a concern, or if you just don't want people looking into your kitchen while you're cooking, then tucking it away somewhere might be a better option.
Ultimately, there's no right or wrong answer when it comes to placing your kitchen in your house. It's all about what works best for you and your family!
