I can understand what you mean and I suppose it's quite normal for you to be confused when come across such kind of content.
First of all, I'd like to re-state your words in a more native way, as below:
Then, I will try to answer your question:
Firstly you should know that in China, when the goverment wants a family to leave their house so that the government can build something on that ground, the government would refund to them according to certain policies. Generally, that family will be guarantted a large amount of money and several new houses. The exact amount will depend on how many people in that family and how big the original house is. In this condition, the house that man owns has 3 floors, which can be considered as big, so this time, the government would refund him nicely, with 3 new houses, just as the text suggests.
