For the University of California, San Francisco, Rafael Viñoly Architects has designed a stem cell research facility that features terraced volumes with green roofs. The project is partly funded by taxpayers in California, where $271 million is earmarked for construction of stem cell labs throughout the state. It’s “one of the largest building programs ever dedicated to a new field of medical science,” says Robert Klein, chairman of California Institute for Regenerative Medicine.
