Designers Ron Culver and Joseph Sarafian have developed a method of casting concrete in Lycra stretched by robotic arms, which they believe could be used to create radical new architectural forms.

Carried out at the University of California, the Fabric Forms project involves pouring a concrete fibreglass mixture into Y-shaped Lycra sleeves stretched into position by six-axis robots.

«This casting method has implications at various scales in the construction site of the future,» Sarafian told Dezeen. «We s
