Building area: For buildings, the building area refers to the horizontal projection area of the land occupied or used by the building, which is generally calculated according to the building area. It is usually used to plan the building density of a plot, and the calculation formula is: building density = occupied area/land area. For flat land, it can refer to the square meter area of blank land, that is, the total area of land. Mu is the unit of land area in China, which is equal to 60 square meters, or about 666.67 square meters.
