With just the press of a button, NCCR Digital Fabrication researchers at ETH Zurich knit a textile that serves as the primary shaping element for curved concrete shells. Now they have used the new technology to create a five-tonne concrete structure for an exhibition in Mexico City.

The heart of the four metre tall curved concrete shell is knitted. The structure’s formwork is a textile supported by a steel cable-net. The prototype KnitCandela marks the first application that this technology is being used on an architectural scale. The structure is an homage to Spanish-Mexican architect Felix Candela (1910–1997) and a collaboration with Zaha Hadid Architects Computation and Design Group (ZHCODE), and Architecture Extrapolated (R-Ex).
