A courtyard house is like a big house with an open space in the middle called a courtyard. It's like a big garden, but it's inside the house!
The courtyard is very important because it helps to keep the house cool in hot weather. When the sun shines down, it gets very hot and the courtyard helps to keep the house cool by providing shade and a breeze.
The rooms in the house are arranged around the courtyard, so you can walk around the courtyard and go into different rooms without needing to go outside.
Courtyard houses are often found in hot countries like Mexico, Spain, and Morocco because they help to keep people cool in the hot weather.
