Then a case study of Sydney Opera House is analyzed, in sketches form. Finally an analogy is developed, that is, as shell growth is a time consuming and layered, process so is the cultural center. Since here cultural center, near Karachi Sea is been developed, hence shell was a very relevant analogy.
