Enhancing low-income capacities for accessing affordable housing is challenge a multi-dimensional requiring different approaches. Low-income families not only lack access to financing for purchasing building materials and hiring masons – they also lack the technical skills to build safe and sustainable houses. PIAC aims to tackle these challenges, as well as the challenge of creating cohesive and self-confident communities by integrating four components under one umbrella through PIAC. The majority of people living in extreme poverty in Mexico lack access to financing for safe, high-quality housing. As a consequence, most low-income families rely on self-construction, where homeowners manage every aspect of building, extending, or refurbishing their homes. Without technical and financial assistance, these families often pay high prices for low-quality construction materials, reinforcing the cycle of poverty. With the success of its Patrimonio Hoy programme, which allows low-income families to access services and building materials through a well-planned savings and credit scheme, CEMEX has integrated other affordable housing initiatives into its holistic PIAC programme. PIAC is designed to enhance low income families’ self-building capacities by offering the training, funding and technical assistance needed to construct their own homes. PIAC´s business model is based on a public-private partnership involving local governments, nonprofit organizations and universities. In this business model, families actively participate in strengthening their capacities and improving their living situations.
