All 25 Epic Project Designs

According to Epic Project FAQ there are 25 Epic building designs,

I have 24 different designs (images attached)

Mountain - 3 designs

Gambling - 3 designs

Beach - 3 designs

Entertainment - 3 designs

Education - 4 designs

Landmark - 4 designs

Transportation - 4 designs

Each design have 3 color variations

You can actually see the different designs before you start doing the epic project.

Anyone know what the 25th design look like?

It must come from one of these specializations (mountain,gambling,beach,entertainment)

Or maybe simcity made an error,and there actually only 24 designs, i already have 24 designs with 3 color variations each, not once i encountered the 25th design.
