Gray Matter Place is a growable Commercial building that appeared for the first time in SimCity 3000. It also appeared in SimCity 3000: Unlimited (known as World Edition in some places), an updated version of the previous game. Despite being a 4x4 building, it is one of the shortest growable Commercial skyscrapers in both games (not including other building sets from Unlimited -European and East Asian sets), and the shortest among the other two 4x4 skyscrapers, being Quigley Insurance (the tallest) and Corporate Ground Zero Plaza.
