ABSTRACT:
An "off the shelf" modular staircase system is described that allows for a flexible fit of the staircase into custom plan areas and/or areas in which the ceiling-to-floor height varies. The modules form a complete staircase and not a mere skeleton of a staircase. Furthermore, the modular staircase system, because it allows for the mass production and conventional transportation of the various stair modules, results in the reduced cost of a staircase and reduced construction time. Individual stair modules may be formed as a unitary structure out of a moldable material.
