Social housing: amphibious dwellings in the Amazon

Bianca Cuvello, Romano Veloso

Project implementation: Brazil
Project development: Brazil

Bianca Cuvello, an architect and urban planner with a degree from the Federal University of Amazonas and a native of Manaus, understands that the urban development of the Amazonas capital is intrinsically conditioned by the natural environment, especially the extensive river basin that characterizes the region. However, rapid urbanization has intensified the phenomenon of peripheralization, creating complex challenges related to social inclusion and access to decent housing. Spatial segregation, in this context, pushes low-income populations to areas where infrastructure is precarious and insufficient.

Given this scenario, amphibious housing emerges as an alternative capable of mitigating these problems, promoting a more balanced integration between residents and floodplain and wetland areas. Amphibious architecture, designed to be built over water, seeks to combine sustainability and technological innovation with construction solutions adapted to the surrounding environment, combining two fundamental structural typologies: stilt housing and floating housing.

This strategy reaffirms the limits and potential imposed by the Amazon's natural constraints, while enabling the occupation of historically neglected and sparsely populated urban spaces. Furthermore, the proposal engages with the city's social and housing issues through design guidelines aligned with the 5 Points for Amazonian Architecture (Cereto, 2024). Therefore, the objective is to reflect on housing solutions that not only respond to Manaus's environmental specificities but also promote the social integration of marginalized populations into the established urban fabric.

Thus, the amphibious housing typology aims to ensure functionality and efficiency, incorporating appropriate equipment and construction systems consistent with local economic constraints, especially in a context marked by scarcity of resources.

We thank everyone who participated and visited the 14th São Paulo International Architecture Biennial, from September 18 to October 19, 2025

NOTE OF CONDOLENCE

With deep sorrow, the Brazilian Institute of Architects – São Paulo Department (IABsp) mourns the passing of architect and landscape architect Kongjian Yu, a global leader in ecological urbanism, and the members of his team who accompanied him, tragically killed during the filming of a documentary. The institute is honored to have had him as a participant in the 14th São Paulo International Architecture Biennial, where his transformative vision strengthened the dialogue between global challenges and local realities. IABsp emphasizes that Yu's contribution, which transcends borders, will remain an inspiration for generations and expresses its condolences to China, to the families of all the deceased, to his friends, and to all those impacted by his genius and dedication.
