Shuttering for mass production of concrete room units comprises an inner shuttering member, and vertical outer shuttering panels each of which is mounted on a rolling and sliding track mounted on a separate support. The outer panels can be moved towards the inner shuttering into a shuttering position, and away from the inner shuttering into a removal position in which they provide between their inner surfaces and the inner shuttering a working chamber in which a person can walk. The rolling and sliding track can be pivoted into a position inclined towards or away from the inner shuttering so that the outer panel moves automatically into the shuttering or removal position respectively.
