A wall spacer is provided at a distance from the inner surface of at least one formwork member (62). This is less than the total width between an opposite formwork member (50) to form an inner mould wall cavity for rammed earth. Also formed are one or two outer mould cavities for a moist, powdered cement render. The render is rammed as an outer layer or layers of facing or veneer jacket simultaneously with earth rammed in the inner or central cavity.
