A pre-cast cementitious construction element (10a) comprises a body (12), at least one coupling member (14) protruding from an edge (16) of the body and at least one coupling member (18) provided at an opposed edge (20) of the body. The at least one coupling member protruding from an edge is adapted to couple with a coupling member at an opposed edge of an adjacent pre-cast construction element (10b) such that, when coupled, a spaced relationship exists between the pre-cast construction element (10) and the adjacent pre-cast construction element (10b). |
