A modular structural system includes a hub in the general shape of a polygon, such as a hexagon or octagon, which may be somewhat rounded or may have a regular shape. The system includes a plurality of other structural members, such as hub spokes, for interfacing adjacent the hub, and leg spokes, for interfacing with the hub or with the hub spokes. The system also includes cross braces for providing additional support between the hub spokes and leg spokes. The hub, the hub spokes, leg spokes, and cross braces are joined by bores in the individual pieces and a plurality of dowels or rods placed into the bores. From these modular pieces, and currently available structural members, many useful and recreational structures may be assembled and then disassembled, such as frames, garden structures, furniture, shelving, and the like.
