The shape is like a gem, a diamond, by using 20m projection for the upper gallery. The visual impact is unique and stunning, as if someone is holding aloft a gem in the sky with an outstretched hand. It has been conceived in such a way so that its towering height is visible from a long distance. BBCC has an art gallery at level 0 and exhibition spaces in level 0 and 1 and 4 where the main auditorium is located. The entrance at level two welcomes with a black-on-black granite pattern into a scenario of tungsten bulbed ceiling (modernity) and Bangla handicrafts (culture) on the walls and all around. A conch shell installation welcomes the visitor to the grand descending staircase.
