Binishells are

air pressure. The original technology was invented in the 1960s by Dante Bini
, who built 1,600 of them in 23 countries.

The original Binishell method needs expensive and sophisticated equipment but it remains as one of the fastest and cost-effective ways to construct dome-shaped, monolithic, and reinforced shell structures.[1]

Development

The original Binishells are circular in plan and are reinforced via a system of springs and

rebars. They can often be constructed in less than one hour.[2] The technology was derived from air structure, which is erected just as a balloon is erected. Bini further drew insights from the pneumatic air-supported tennis dome. In 1965, the first Binishell was built. It had a 12-meter diameter, 6-meter height, and was lifted using Bini's patented pneumatic formwork.[3]

Uses for the Binishells range from

discothèques. An example of a Binishell was opened in 1978 as a sports hall for the Malvern Girls College. This Binishell had a size of 36 meters in diameter.[4]

Later, Bini designed a smaller version of the Binishell, known as a Minishell, as a low-cost, 8-meter by 8-meter shell structure. In 1971, several Binishells were constructed in Australia, for a governmental initiative that required rapid building system for multi-purpose centers.[5] Bini also completed the construction of a tourist village in Cairns, Australia, using Minishells in 1980.[4]

More recently the system is being re-launched by Dante Bini's son Nicoló Bini, AIA. Improvements to the original system include greater architectural flexibility, compliance to international

heating/cooling technologies. It is touted as a sustainable building technology since it is said to have one-third the environmental impact over its lifespan. The prototype for this new technology, called System A was completed in Malibu for actor Robert Downey Jr. [6] [7]

The latest Binishells technology no longer requires air pressure, but relies on tensile forces to give shape to a parabolic hyperboloid shaped building envelope. The resulting building has all the safety and environmental benefits of the improved Binishells, but has added advantages. These additional advantages include a rectangular floor plan, multi-floor capabilities, built-in openings and natural venting. The two story prototype for this technology was built on Vancouver Island, BC Canada.[8]
