From Team X and Metabolism in the 60s to High-Tech, Europe and Japan seemed to have dominated the discourse of open works. Today we turn our eyes to Lina Bo Bardi, a most underrated architect in South America and the pioneer of Brazilian modern architecture who advocated open-ended works. MASP could be viewed as a writer’s text from the perspective of Roland Barthes, so we would reread open works and open-ended spaces from MASP to contemporary architecture, from the dimensions of Lina’s typical past works, Sao Paulo’s urban context, the culture of Paulista Avenue, ontology of MASP, comparison between open works and open-ended proposals etc.
