BIG, MVRDV, Snohetta and aMDL have unveiled images of their proposals for the redesign of San Pellegrino flagship factory and bottling plant located at the source of the mineral water in San Pellegrino Terme, Italy.The competition brief asked architects to renovate and expand the historic home of San Pellegrino, the world’s leading sparkling mineral water company, with a “truly innovative and technologically-advanced design” aimed at integrating into the natural aesthetic of the surrounding terrain, while responding to the iconic identity of the S. Pellegrino brand.Located in the Brembana valley between the Brembo river and at the foot of the Italian alps, our proposal embraces and enhances the existing architecture while forming an elegant framework.
