A double-curved concrete shelled pavilion was made with 3D-knitted formwork. It was developed by Zaha Hadid Architects and ETH Zurich.

The pavilion named KnitCandela is on display in Mexico. They built using KnitCrete. This is a new 3D-knitted textile technology for creating curving concrete structures. There is no need for expensive and time-consuming moulds.

The knitted fabric weighs just 25 kilograms and the cable net 30 kilograms. The concrete shell weighs 5 tonnes. There is 100 times more concrete than fabric and cable.
