Answer
The Vanna Venturi House, designed by Robert Venturi for his mother, is a renowned example of postmodern architecture. Completed in 1964, it challenged the prevailing modernist aesthetic with its fragmented forms, symbolic elements, and playful juxtaposition of historical and vernacular references. The house's iconic "gable" is a trompe l'oeil, while the asymmetrical facade features elements such as a Palladian window and a garage door disguised as a barn door.
