Abstract
A paving element has a body with oppositely directed major faces interconnected by a peripheral side wall. One of said major faces is generally planar and has at least one set of a plurality of predefined areas formed thereon. Adjacent areas of the set have a surface finish to provide a contrasting visual effect relative to other areas of the set. The finish and disposition of the areas is configured to provide a representation of abutting orthogonally disposed surfaces so that when a plurality of such sets is arranged in seriatim, a visual impression of stepped surfaces at different levels is provided.
