Instructions
Cut Styrofoam blocks into the shape of bricks. The bricks can be any size, just as long as they are evenly proportioned.
Pile one Styrofoam block on top of another to form a column. Tape each block to the one below. Continue adding blocks until you have reached the desired height for your gazebo.
Make three more columns of Styrofoam blocks. The four columns should together form a square or a circle. Each of the columns should be evenly spaced.
Place a large sheet of Styrofoam, or a Styrofoam board, over the tops of all four columns. Smaller sheets or boards can be taped together.
Secure the roof to the tops of the columns either with tape or by placing a weight on top of the roof at a point directly on top of each column. Using a weight instead of tape will make your roof removable. That way you can take your Styrofoam gazebo apart and re-assemble it.
