Alison Knowles. The Big Book

The Big Book by Alison Knowles was just that: a book. Comprised of eight moveable pages--each four-feet wide by eight-feet tall--anchored to a metal spine, this walk-in construction was equipped with casters, which made it possible to leaf through individual pages. Each page had access to the next, opening up different spaces between them, where a reader could spend some time. The book contained a toilet, an artificial-grass sleeping tunnel, a gallery (with works by artist friends), a guest-book, a library, a stove, a telephone, a window to open, close or climb through, electric lights and other utensils in the spaces between the pages.
