Abstract
An assembly for creating a three dimensional exterior structure incorporates a plurality of bodies inter-assembled via engaging tongue and groove profiles to create at least one of a multi-tier stepped or extending walkway surface. Each of the bodies further exhibits a hollowed interior to facilitate in-filling of a compactible material in order to weight said bodies during assembly. Either or both of thermal generating elements or effect lighting can be incorporated into one or more of the bodies. The bodies can also include tiered or stackable step blocks, each exhibiting an interior ledge for supporting a thermally conducting insert shelf or pad, additional rectangular assembled blocks providing tongue and groove engagement and supporting the underside of the step blocks.
