The kitchen should not be completely enclosed in the house. At least one side of the kitchen should face the open space (such as balcony, patio, backyard, etc.) ), and should not be closed or placed in the middle of the room. This situation is very common in self-built houses afterwards. The kitchen, which was originally behind the house, became the middle of the house after being built in the back, which not only hindered hygiene, but also affected family fortune.
