The purpose of this article¹ is to analyze the link between architectural aspects of Lina Bo Bardi’s (LBB) main work, focusing on the creation of the great living space, and heractivity as a researcher of Brazilian popular culture and, especially, of handicraft. Given its meaningfulness and complexity, to deepen in the understanding of the author’s intentions and the means employed by her to achieve them, it will be necessary to focus on buildings in their formal, functional and symbolic aspects. Further works, records or manifestations from LBB, as well as from other architects, will be called upon as references to define similarities or differences in relation to the positions observed in SESC Pompeia.
