Definition
A superstructure is the part of a building or structure that is above the main supporting structure or foundation. Think of it as the visible part of a building above ground level. It could be the upper decks of a ship, the part of a bridge above the piers, or the stories of a building above its base. The superstructure is often lighter and more elaborate than the substructure. It serves various functions, including providing living space, supporting equipment, or creating an aesthetic design.
