Boston’s Institute of Contemporary Arts is on track and on time for next September’s opening of its much-anticipated new home on the city’s waterfront. “The new ICA, designed by the New York firm Diller Scofidio + Renfro, will be marked by a distinctive glass cantilever that stretches out toward Boston’s harbor. Inside, it will feature a 325-seat theater and two-story educational center. The 65,000-square-foot museum will triple the ICA’s current exhibition space… ICA leaders hope the museum will transform an institution that’s been considered no match for its counterparts in other major cities.”
