The Malestrazza Building functions as both a physical space and psychological prison. Its architecture becomes a weapon, trapping characters in cement-filled spaces and confined passages. The building mirrors the characters' internal emotional cages, Malestrazza's obsession with control, Mary's protective secrecy, and Jimmy's twisted sense of obedience all manifest through the structure's design.

Walled In explores three interconnected themes: Confinement, where physical entrapment in walls and shafts mirrors psychological imprisonment; Obsession, driving characters like Malestrazza's ritualistic murders and Mary's protective control; and Revenge, as Mary's quest to avenge her husband and daughter Julie leads to cycles of violence that perpetuate rather than resolve trauma.

Malestrazza is the architect of the building that bears his name. He views construction as a ritual of human sacrifice, designing the vast central shaft as his 'masterpiece' where he entombs victims. His charm masks a cold, calculating need for control over life and death. He ultimately becomes trapped in his own architectural tomb.
