In 2016, Pritzker Prize winner Alejandro Aravena announced that his firm, ELEMENTAL, had released the rights to four of their social housing projects, and all documents would be uploaded to their website for public use. Aravena’s goal was to start a movement in which architects would work together to tackle the world’s challenges around housing shortages and affordability, especially with increased migration. The shared drawing sets and a description of the project’s principles provide architects with the necessary documentation for building a low-cost home, encouraging designers to do the same with their work, contractors to assist in building these homes, and governments to shift their thinking of how they can approach mass urbanization. Six years later, how has the concept of open-source architecture progressed, and how has it impacted the architectural profession ever since?
