Room boxes are deeper than window boxes and usually show one or more complete rooms, including entire one-room shops or houses, potting sheds, and garages. Window boxes differ from room boxes in that they usually display only one view of a vignette, and are usually no deeper than three or four inches. It is especially good for school displays where costs must be minimal or for placement inside baby houses, dollhouse bookcases, or glass-fronted bookcases, where a collection of simple room boxes can be used to finish a dollhouse room by room. Like standard room boxes made from Davey board, breakaway boxes can have standard dollhouse windows and doors fitted to their interiors.
