ETH zurich’s block research group completes complex, doubly curved concrete roof
the roof forms part of NEST, a building that provides space for testing new construction technologies in practice.

after successfully building a prototype in 2017, researchers from the block research group (BRG) at ETH zurich have now completed a complex, doubly curved concrete roof in switzerland. the roof has been designed for NEST (next evolution in sustainable building technologies), a modular research and innovation building that seeks to accelerate innovation in the construction sector. conceived by gramazio kohler architects, NEST provides space for testing new building technologies in practice.

NEST is owned by research institutes empa and eawag and is located on empa’s campus in dübendorf, 30 minutes outside of zurich. designed for the building’s HiLo unit, the roof has been completed by researchers from the block research group at ETH zurich in collaboration with partners from the construction industry. the expressive shell structure demonstrates how high (Hi) performance can be achieved with low (Lo) embodied emissions by combining efficient concrete structures with novel fabrication and construction methods.

built on a cable-net and fabric flexible formwork, the project was realized through an integrated design-engineering-fabrication-construction process made possible by the open-source computational framework COMPAS. after years of research and development, the concrete roof is now complete and open to the elements. work on the construction site is continuing with interior work to begin in the coming months. the HiLo unit will be completed in 2021.
