ZGF, in association with SOM, provided master planning, programming, and design for the new Mortimer B. Zuckerman Research Center in Manhattan. The two-phased project replaces outdated laboratories with new facilities that enhance Memorial Sloan Kettering’s campus and creates a distinct image for research. The completed first phase is a 558,000 SF, 23-story laboratory tower that includes wet laboratories and core research and teaching programs, as well as a new rectory for an adjacent church. Programmatic functions are organized into three clear architectural components: a laboratory bar with linear equipment room and support, a public circulation spine, and an office / interaction cluster. A glass-enclosed communicating stair, with adjacent conference and lounge spaces at each level, creates a focal point for interaction for the entire building. The first phase has achieved LEED Silver®. Phase two is a 187,436 SF connecting seven-story addition that will incorporate computational biology and graduate school programs, as well as a 350-seat conference center.
