I had been inspired by a trip to the Science Museum (in the mathematic section) where they had turned mathematics into art. 

The fabric could be pulled in tension by ropes, attached at opposite angles to form a twisted column. It could be the ropes on their own or maybe as the sole integral structure and wrapped in the fabric as a skin, with the ropes to protrude out. This would allow light to filter through the pavilion as well as to segregate the space. These could incorporate the weighted sand idea, with sand filled balloons.  

Image from the Sci museum also to explain further.
