First, you have to go through a 4 year college course at a construction institute with arts. I recommend The Art Institutes. After you get your masters degree, collect your Brick Licensed.
*You have to set up a meeting with the CIA about the exact location and dimensions of the brick you are making. After that, make sure you can get medical assistance to make sure nothing goes wrong.
You also need a Brick Placer, you can get one at your local Super Secret SWAT base across the street from Ephialtes. Make sure there are no Santa Mechs. Go inside and show them your Brick Licensed. You will then have to purchase a Brick Placer for the price of 6000 Robux.
Go back to the exact location you were allowed to legally place a brick.
*You then can place your brick
TO create another brick, repeat steps marked with *
Each brick can only be made once a day
Happy brick making
