A closet, traditionally defined as an enclosed storage space within a building, serves practical purposes in architecture, from built-in wardrobes to utility rooms.

Richards depicted its spatial transformation, blurring boundaries between restriction and expansion. These varied portrayals underscore the closet’s dual role—as both a functional structure and a metaphor for concealed realities, personal sanctuary, or psychological strain.
