The present invention relates to a modular masonry step and deck assembly consisting of a plurality of like-shaped risers and a plurality of like-shaped treads that enable the assembly to have a variety of shapes, sizes and heights to provide a custom fit to a variety of buildings, mobile homes or trailers. The risers are dry stacked in a multi-tier, mufti-column, multi-row arrangement to form a base of the assembly. An inwardly expanding goove is formed in each corner of each riser. When aligned flush with adjacent risers and dry stacked one atop the other in a stacked bond arrangement, the groves form a continuous vertical channel. A semi- flexible locking key is formed inside the channel to secure the risers together, but accommodate movements caused by the freezing and thawing of the ground. Four differently shaped treads are used to form the walking surface of the step and deck assembly. Each tread shape is used to form a specific portion of the walking surface. A plurality of each like-shaped tread is used to form its specific portion of the walking surface to create a continuous lip around the perimeter of the steps and deck. Each of the four like-shaped treads has a specific design on its top surface to form an integral, continuous pattern on the steps and deck. The treads can be used to continue the design into a walkway.
