You are probably familiar with straw bale buildings, but what about straw wattles? Also known as straw worms, bio-logs, or straw noodles, these straw-filled tubes are cylinders of compressed, weed-free straw that is encased in jute, nylon or other biodegradable materials. Typically laid down as a form of erosion control, New York City and Mexico-based "design farm" Bittertang has instead created a living ampitheatre made of these tubular, straw-filled wattles.
Installed as a temporary performance space for Ragdale, a non-profit artists’ community located in Lake Forest, Illinois, the Buru Buru ampitheatre is constructed using a radial framework of trusses which the straw wattles are layered upon and attached to.
Intended to gradually transform into a verdant hillside shelter that blends into its surroundings, Buru Buru stands out as an unconventional example of straw building techniques. You can see more images over at Designboom and Bittertang.
