In terms of our LSAA Design Awards, a Medium sized Fabric Structure, or tensioned membrane structure, would have a surface area of between 250 and 1000 sqm.

Tensioned fabric or membrane structures of this size are often of one geometric form such as a conical structure with a central bale ring attached to a mast or tied down. The perimeter could be a series of edge cables, trusses or beams. If multiple units are used they the final structure may fall into the "large" category.

Other forms could be panels with internal diagonal arches, crossed arches, barrel vaults with intermediate valley cables.
