This chapter discusses the multidisciplinary project Autoconstrucción by Mexican artist Abraham Cruzvillegas, which relates the story of his childhood through the self-build construction of his family home on the volcanic lands of the Pedregales de Coyoacan outside Mexico City. The first in a series of realizations for Autoconstrucción began far from the precarious spaces of Mexico City, when Abraham Cruzvillegas took up a 6-month residency at Cove Park and the Centre for Contemporary Arts in Glasgow in 2008. During that time, the artist created his customary sculptures of found-objects, produced a book documenting his experiences growing up on squatted lands of the Ajusco, and wrote the lyrics for 18 songs that were then offered to a diverse range of local Glaswegian bands. An in-depth analysis of this particular aspect of the project is explored, which extends into a broader discussion about the wider contribution of social art practice in the critical discourses around urban informality and user-generated urbanisms. It also explores how the personal experiences of self-build, self-organized communities have formed the methodology of Cruzvillegas’s social practice, artistic sensibility, aesthetics, poetics and politics that raise critical challenges to current debates around precariousness in art.
