Why is studio apartment small

Well To me, studio apartment are design to suit the needs of a single person. They cannot raise a family there because it's just too small.Plus if they would have childrens. It would be kind of awkward for them to be in the same room.

Other than that your privacy is exposed to your friends and famiIlies who came to visit you. It would be so embarrassing . If they would found something that you wouldn't want them to find. Hehehe...
