A space frame (10) has upper chord lower grids (12, 14) of intersecting chords (16, 18). The chords (16, 18) are interconnected by bracing modules (30), the bracing modules (30) being spaced apart from one another in each grid direction. The bracing modules (30) are formed from four bracing members (32), the bracing members (32) being arranged in mutually inclined pairs, the bracing members (32) of each pair extending between upper and lower chords (16, 18) extending in the same grid direction. Each pair of bracing members (32) crosses the other pair of bracing members (32), the point of crossing (34) coinciding or being positioned between each member of the other pair of bracing members (32) and either the upper or lower chord (16, 18) associated with the other pair of bracing members (32).
