A house is a building for people to live in. It is usually built for a family (parents and their children) to live in.
Most modern houses have special areas or rooms for a person, or a family group to do the things that they need to live comfortably. A modern house has a place to cook food, a place to eat, places to sleep and a place to wash. These things are usually done in separate rooms, which are called the kitchen, the sitting room, the bedrooms, the bathroom, and the toilet (or lavatory)
