Gregor Schneider's *Totes Haus ur Rheydt* is an unsettling and obsessive architectural intervention in which the artist spent years painstakingly constructing new walls, rooms, and passageways within his family home in Rheydt, Germany, effectively building one house inside another. The result is a labyrinthine, claustrophobic space where sealed chambers, bricked-up windows, and hidden corridors evoke a profound sense of psychological dread and spatial disorientation. The work blurs the boundaries between domestic familiarity and existential unease, transforming the mundane structure of a home into a haunting meditation on isolation, obsession, and the uncanny.
