In one aspect, there is provided a lost column formwork shell portion comprising an elongate body comprising a generally u-shaped cross-section shape comprising a pair of lengthwise extending edges, an inner side and an outer side, and at least one spacer element depending from the inner side of the shell portion and projecting inwardly. In a further aspect, there is provided a lost column formwork shell assembly comprising a pair of shell portions joined along their lengthwise extending edges. In a further aspect, there is provided a lost column fonnwork assembly a shell assembly, bracing and reinforcement.
