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.
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.

APPLICATION OF PROJECT:
The project was to design and install a unique waterproof shade structure to a Year 11/12 study area at an elite private Grammar School in Sydney.
The area under cover is 760sqm. The space to be shaded was clearly defined and located between the austere 19th century red brick buildings on a second floor flat tiled roof
Beyond a school’s playing fields, exposed concrete surfaces often represented the extent of outdoor space in many schools built a century ago. Knox Grammar was no different. Today the definition of outdoor space is much more exciting and open to design possibilities. For schools with resources, outdoor spaces can be unique, comfortable, multifunctional and aesthetic.
This project was designed to deliver a modern purposeful student space in an old fashioned but elite private school environment. The shape of the courtyard was not regular. It had an outward projecting building through the centre of the courtyard. The structure had to straddle both sides of the courtyard and protect two sets of doorways. A “U” shaped double intersecting snake cantilever was born.
