Now in its fourth year, Boston Design Week once again showcases the area’s design community through special parties, programs, tours, demonstrations, open studios and more beginning March 29. The scope expands this year as not one, but five, kickoff events take place throughout Boston and its suburbs, and museums outside the Hub, including Salem’s Peabody Essex Museum and Brockton’s Fuller Craft Museum get in on the action. It all culminates in the 10th annual AD20/21: Art & Design of the 20th & 21st Centuries—which also encompasses the 18th annual Boston Print Fair—at the Boston Center for the Arts’ Cyclorama April 6–9. AD20/21 gets off to a great start with a gala preview on April 6 from 5:30–8:30 p.m. featuring fine food, wine and music, along with a reception honoring decorative arts curator Jonathan Leo Fairbanks, the 2017 recipient of the AD20/21 Lifetime Achievement Award, all to benefit Design Museum Boston.
