Things You'll Need
Instructions
Place one 4-by-6 unit plate on a flat service with the longer sides vertical.
Line up two 4-by-1 unit plates on the right and left side of the 4-by-6 plate leaving a one unit overhang at the top and bottom so that the resulting surface resembles a 6-by-6 square with the corners removed.
Place a 4-by-6 unit plate on top of the corner-less square with the longer sides horizontal. This piece will join the three plates below.
Lay a 4-by-1 unit plate parallel to the 4-by-6 unit plate on the top and bottom. This will complete the supportive base plate.
Repeat Steps 1 through 4 to complete three additional base plates. Set aside two plates.
Fill every available space on the plate with 1-by-1 bricks. Stack bricks 10 units high.
Fit one of the pre-constructed base plates on top of the cylindrical structure.
Repeat Steps 6 and 7 to build a second story and complete the 20-unit high cylinder.
