The Lapa Bus Terminal (2002) by Brazilian architecture firm Nucleo de Arquitetura. The building is one of 18 projects by six Brazilian firms profiled in “Coletivo: Contemporary Architecture from Sao Paulo,” on view through April 25 in the Sam Fox School of Design & Visual Arts’ Steinberg Hall Gallery. “The title of the exhibition evokes dual meanings,” said Zeuler Lima, Ph.D., assistant professor of architecture, who organized the show and will present a gallery talk at 12:30 p.m. Wednesday, April 16. “First, it refers to the educational background/patrimony shared by the designers,” who studied at the University of Sao Paulo’s School of Architecture and Urbanism, where they were influenced by the work of architect Vilanova Artigas, Lima said. “Second, the work produced by each firm emphasizes collaborative work over individual authorship.” For more information, call 935-6200.
