The plot is centered on a (possibly fictional) documentary about a family whose house is impossibly larger on the inside than the outside. The format and structure of House of Leaves is unconventional, with unusual page layout and style, making it a prime example of ergodic literature.[1][2] It contains copious footnotes, many of which contain footnotes themselves, including references to fictional books, films or articles.[3] In contrast, some pages contain only a few words or lines of text, arranged in strange ways to mirror the events in the story, often creating both an agoraphobic and a claustrophobic effect. At points, the book must be rotated to be read. The novel is also distinctive for its multiple narrators, who interact with each other in elaborate and disorienting ways.
