The unnatural acoustic space of Das Haus : A 'three-dimensional' radio play adaptation of Mark Z. Danielewski's House of Leaves.

This article examines the challenges and possibilities of adapting Mark Z. Danielewski's novel *House of Leaves* (2000), focusing on the German radio play adaptation *Das Haus* (2010). The novel's story centers on a house with physically impossible dimensions and is notable for its experimental print form that resists straightforward film adaptation, emphasizing sound as a key modality to evoke its uncanny spatiality. *Das Haus* innovatively presents the narrative across three simultaneous radio channels, inviting listeners to switch between them to navigate the story's layered perspectives, thereby using the dynamic, boundary-less nature of acoustic space to represent the novel's "unnatural" spatial environment. The radio play exploits sound's indexical qualities to manifest the story's disorienting and paradoxical spaces, creating a productive tension between narrative and acoustic space that aligns with the novel's themes of spatial ambiguity and sensory perception.
