Before beginning, remove all the Entrance Station pieces from your storage box.
You should have 12 pieces.
Step 1
First, slide the two Inner Side Walls onto one of the Front/Rear Walls, on either side of the five windows. Always make sure the engraved details are facing out. The pieces might feel loose for now.
Parts needed: Front/Rear Wall, Inner Side Walls (x2)
Step 2
Next, slide the remaining Front/Rear Wall into both empty slots of the side wall pieces. Everything might still feel loose at this point.
Parts needed: Front/Rear Wall
Step 3
Holding everything together, side the two Outer Side Walls up into place.
Parts needed: Outer Side Walls (x2)
Step 4
Next, snap the two Middle Roof Sections into place over the middle of the building. Be sure to press firmly so they snap all the way in.
Parts needed: Middle Roof Sections (x2)
Step 5
Finally, snap the four Side Roof Sections into place. Be sure to orient them correctly as there is a left and right version. In order to get them aligned to snap in, you’ll have to force the edge of the front/rear walls out of the way before you can snap the roofs in place.
Parts needed: Side Roof Sections (x4)
