27) Cut out each Tower. Make note that one of the upper tabs in each of the towers has a slot in it. This will fit into a matching slot for the roof piece. Also make note of the blank patch at the bottom of each tower, this will later be glued to the plaza.
28) Note the light grey corners. These are separate faces, each twin tower should have 8 sides: four main faces and four corners. These should be angled 45 degrees relative to the main faces.
29) Fold all tabs on Tower 1. Then all vertical faces. Glue the vertical tab Straighten the tower as much as possible.
30) Making sure the blank spot on the side of the tower is pointed toward the plaza, glue Tower 1 to its place on the base. Make sure to glue the small white patch to the plaza, this greatly increases stability.
31) Taking Tower 1's roof (The one without the blue observation deck), use a small knife to put a small indentation in the white circle in the middle of the roof. This will allow for easier attachment of the antenna. It's okay if you dig a small hole in the roof, as long as it isn't huge.
32), slide it into the slotted tab in Tower 1. Glue in place.
33) Repeat steps 29-32 for Tower 2.
