In the future, people will build houses on the moon. The best place for houses in a moon town will be underground. Underground houses will be safe, and the temperatures will not be very high during the daytime and not very low at night. Moon homes may be balloons with oxygen, and people will wear oxygen masks when they are away from home because the moon has no air around it. The house might have beds, tables, and chairs, so people will sleep, eat, and work in their homes. Moon-house building will be easy.
