In our daily life, we know that many buildings are building more and more floors when they are being built. This is mainly due to the fact that the price of land is higher and higher when the country sells its land. Because if there is no way for the land to be able to sell such a high price, this piece of land will certainly not create the benefits it should have. Then the developers in the land purchase, on the basis of the existing land, we hope to create greater value. The higher the floor is built, the more value it can bring to itself, so the higher the building is now. And since the building of the floor is higher, it will be found to be a very good use for the land.
