This research deals with urban housing in Brazil, notably in the period that goes from the second half of the 19th century to the middle of the 20th century, having as its north the transformations resulting from the search for modernity, health and comfort and their relationship with the architectural styles adopted. For that, it analyzes the residences built in the central region of the city of Teresina, founded to become the capital of the State of Piauí, which, together with social and economic factors, technical limitations and local climatic conditions, originated an architecture of very peculiar characteristics. It seeks, therefore, to understand and characterize the transformations that took place, as well as their diffusion in the city, focusing on the agents involved in this process and on the appropriation of the Teresina society of the different residential typologies. It is based mainly on documentation consulted in local and private archives - such as almanacs, newspapers, reports, legislation and images from the time -, surveys, interviews, as well as bibliography of local historians, with emphasis on Teresinha Queiroz, Monsenhor Chaves and Odilon Nunes. In order to support the analyses, it also seeks theoretical support in consolidated authors such as Carlos A. C. Lemos and Nestor Goulart Reis Filho. It contributes, in this way, to broaden the knowledge of the production of urban housing in Teresina-PI, so little present in the historiography of Brazilian architecture.
