Cubierta Voronoi was the first ETFE roofing system designed and installed in the history of Mexico. The ETFE tensile structure is the meeting point of the new shopping mall located in a neighborhood of San Pedro Garza Garcia, Monterrey.

The structure consists of a tree-like steel masts which support a “honeycomb” covering steel structure. The panels of the honey were cladding with ETFE air-inflated cushions featuring transparent ETFE film on the bottom and white ETFE on the top. The surface descripted by the roof was divided into panels by the algorithm developed by Mr. Voronoi, and thus named a Voronoi structure.

The big achievement of this design was to build the freeform roof only with 5 different cushion designs. As a result, the production process was accelerated, and construction and planning costs were decreased. Also, the assembly process was standardized, and all 100 cushions were installed in only 12 days.
