The Urban Stack is a pedagogical framework for understanding the infrastructures of power that operate in relationship to practice. These elements shape the design and production of the built environment in a time of increasing uncertainty, project complexity, and risk. As a research unit, the Urban Stack lab explores the impact and opportunities presented by the emergence of scalable systems in the built environment, and is building and testing productive overlaps between the digital, social, and design processes that shape urban form and civic futures in 21st century urban places. The lab is developing technologies that embrace the complexity of social infrastructures and market dynamics to produce new modes of design practice. The persistent and growing challenge of housing supply and quality is a primary focus of current Urban Stack research.
