The island is made up of sixteen houses, of which ten have become museums: four show the struggle for housing in the city and the other four, how people lived in the Bon Pastor neighborhood and the evolution of the interiors of the cheap houses between 1929 and 2017. The remaining two show general aspects of the themes represented.
The process of creating the space has been made possible by the complicity established between the neighbors, the District of Sant Andreu, and the MUHBA (ICUB). The Cheap Houses museum project was started in 2010, at the initiative of the Association of Neighbors and Neighbors of the Good Shepherd, which obtained the support of the District of Sant Andreu and the Municipal Institute of Housing and Rehabilitation of Barcelona.
