From its permaculture food gardens to neighborhood brick-making workshops, to robot-traced empty lot block party takeovers, the 2021 Chicago Architecture Biennial (CAB)— under the direction of artistic director David Brown—was very much at home far from the downtown space that hosted previous biennials. But this spring, the Biennial is making a triumphant return from some of Chicago’s most disinvested neighborhoods to the Beaux-Arts-style Chicago Cultural Center in the Loop. The Center’s newly opened CAB Studio will become a venue for exhibitions, programing, and youth and family activities that will give the biennial a year-round home for the first time.
