A lift wall comprising a ceiling module to which two wall cloths have been affixed and within which a lifter and power units are accommodated, the lift wall together with its ceiling module constituting one unitary unit mountable as such on the ceiling. The wall cloths are mutually connected by framelike connector elements, with the wall cloths spaced at a constant distance from each other. The connector elements are located over each other in registry and mutually spaced. The lower edge comprises an elongated lower edge element lying in a horizontal plane and running parallel with the wall to which wall cloths and lifting members are affixed. Two elongated lower bracing arms running parallel with a lower edge element and attached thereto with the aid of linkage arms pivoted in a vertical direction, at right angles to the wall plane and placed in registry with each other to be displaceable with reference to the lower edge element upward and in braced fashion to either side, the bracing arms being disposed between the wall cloths in such manner that the cloths are folded to the sides, braced by the bracing arms, when the lower edge element is lifted up with the aid of the lifting members.
