Oga’i House


Incremental housing solution for Mbya Guarani communities in Caaguazu, Paraguay.

Product description Brand name and product description

The Oga’i House is a housing typology developed by CEDES/Habitat for and with the participation of the Mby’a Guarani indigenous communities living in the region of Caaguazu, Paraguay. The design of the Oga’i House follows the construction principles and cultural costumes of the traditional houses of the Mby’a Guarani community. The project also incorporates alternative building materials to replace or decrease the use of depleted resources such as wood.

Due to the remote location of these communities and difficult access to infrastructure, designers implemented passive design strategies and mechanisms such as low-tech interior airflow strategies, construction of new kitchen stoves to reduce the impact of smoke in the interior, hybrid roofing techniques combining standard and local materials to avoid Chagas disease spread, and external solar sanitary and shower system.

The Oga’i House initiative was co-designed between CEDES/Habitat and the Asociación Mborayhu Porã – Mbya Guarani, co-financed by the Ministry of Urbanism, Housing and Habitat of Paraguay through a social housing grant subsidy and benefited communities, assisted by the Architecture, Design, and Arts School at the National University of Asuncion, and executed by the construction company Altec S.A.
