The Block Research Group, headed by structural designer and professor Philippe Block, is dedicated to “pioneering novel design and engineering approaches for efficient structural forms and proposing economical construction methods.” Based at ETH Zurich, their research proposals and prototypes have been exhibited at Venice Architecture Biennale and other venues around the world. Their projects have explored a variety of structural assemblies, using traditional building materials like concrete and stone, but also looking at how waste, mycellium, and even fabrics can be used in architecture and engineering.

The latest project, Lotte Scheder-Bieschin's Unfold Form, is aimed at using concrete, the most common structural material today, more efficiently. The lightweight formwork made from plywood panels connected by textile hinges, capable of supporting 1,000 kg (2,200 lbs) of concrete, results in corrugated vaults that save up to 60% concrete and 90% reinforcement steel per typical concrete floors. Although the fabrication of the intricate formwork appears time-consuming, as seen in the photographs and short film below, the formwork is reusable, which is a plus, and it results in a beautiful finished product.
