I thought I would have an easier time finding threads that discuss this.
A house is a single building that people live in.
A home is where you live, where you fee you belong, where you feel secure.
You can stay in a house while you're visiting somewhere, but it's not your "home." On the other hand, you can have wonderful friends and when you visit their house, you DO feel like you're home. You have an emotional connection to your home, which can be a house, a flat, or even a small room in someone elses' house.
