You can only consult the salesperson. The lower floors in Shell House Search automatically pop up based on the total floor. If the house has a total height of six floors, the 1.2-story shell system will generally show that it is a low floor. If the house has a total height of 11 floors, the third floor and below are basically low floors. If the house has a total height of more than 20 floors, the fifth floor and below are low floors. Well, if it is a house with a total height of thirty or forty stories, the lower floors are basically the eighth floor.
