Earth still is one of the most common building materials in the world, and is said that because of its low-tech approachit is a good option for self-construction and mutirão — Portuguese word for collective mobilization for mutualassistance in a free character. The problem addressed is the feasibility and social gains of the mutirão practice in cobbuildings. The case study is an earthen house that the author designed and self-built in the rural area of Pelotas-RS,southern Brazil, where more than 80 volunteers helped to build. The general objective is to study the possible gains ofthe mutirão practice, and the specific objectives are: a) to define the concept of natural construction and explain thebuilding technique applied in the house studied (cob); b) to analyse the relationship between mutirão and the complexityof the building technique; and c) evaluation of the observed social sustainability gains. The results showed thatthe mutirão sessions attracted many helpers due to the curiosity about learning an unconventional technique. Theyhave also contributed to a more playful work environment, despite hard work. It is concluded that natural building andmutirão complete each other, and can collaborate for practical gains of social sustainability.
