Several solutions of theaters built with unfolding or collapsible structures; conceived both as changeable or permanent constructions. They do not require a foundation. An appropriate structure levels and sustains a stand. Rain water flows freely underneath when the construction is temporary. These are enclosures sufficiently conditioned for outside temperatures of from — 2 °C to 37 °C. They are planned in general for use as theaters and for the projection of films using special systems.
