WASHINGTON — The Kennedy Center announced Tuesday that it plans to build a $100 million expansion to the nation’s busiest performing arts venue. Designed by American architect Steven Holl, the privately funded project would help connect the multitheater complex with Washington’s waterfront and includes public green spaces, a video projection wall for simulcast productions, and a floating outdoor stage on the Potomac River.

The new plan, which pays tribute in its architectural detail to President John F. Kennedy, includes three pavilions to house classrooms, rehearsal facilities, and multipurpose rooms for the center’s educational programs. The expansion, south of the 42-year-old complex, aims to solve some of the most pressing space constraints for a facility that hosts some 2,000 performances each year.
