How many brick is it to build the outside of house?

It depends on the size and design of the house. An average-sized single-family home could require between 1,500 and 2,500 bricks. However, this number could vary significantly depending on the type of brick, the size of the home, the type of bond, and the amount of detail in the design. For a more accurate estimate, it is best to consult with a builder or architect.
