Just as we learned Columbia University had lost its battle to expand into West Harlem, another prominent US school, Harvard University, announced Thursday it is mothballing construction of its $1 billion Science Center, designed by Behnisch Architekten. The building is the centerpiece and first in a series of projects of a sweeping campus expansion plan in nearby Allston where the University owns 350 acres. The campus masterplan, created by Cooper Robertson & Partners, Frank Gehry and the Olin Partnership, calls for four to five million sq ft of new facilities including academic spaces, student housing, museum and performance spaces.
