This study aims to investigate the perceptions and barriers around the use of earth architecture in mutual aid housing cooperatives in Uruguay and to assess how this option could be a viable implementation in such collectives. Several interviews were carried with different actors in Uruguay, namely architects specialized in earth architecture, academia, government, Uruguayan Federation of Mutual-Aid Housing Cooperatives (FUCVAM) and Technical Assistance Institutes (IATs). Moreover, in the context of mutual-aid housing cooperatives, equally important is the investigation among cooperativists on the perceptions, reasons and barriers for adopting this mode of construction on their own cooperatives. After assessing those factors, recommendations will be provided in the context of Uruguay and Uruguayan mutual-aid housing cooperatives.
