The modern sustainability project is built on the promise that evolving technologies can reconcile urban and economic growth with ecological responsibility. By the metrics developed by the built environment professions and the policies adopted by governments, progress is tangible and accelerating: buildings consume less energy per square foot than they did a generation ago, vehicles emit fewer pollutants per mile, and urban infrastructure is more integrated and measurably cleaner in many cities. And yet total resource consumption continues to rise. Sustainability, as currently practiced across the built environment professions, has become a strategy for optimizing consumption rather than reducing it. Until the profession is willing to question the scale and structure of demand rather than the efficiency with which that demand is met, its most celebrated achievements will continue to fall short of the problem they claim to address.

Stretching along the Atlantic coast at the southern tip of Florida, Miami is often introduced through postcard views of beaches, palm trees, and glass towers facing the water. Yet, behind this familiar image lies a city shaped by migration, tourism, and real estate cycles, where architecture has repeatedly been used to project new identities and reinvent the urban landscape. From early resort hotels and the Art Deco façades of South Beach to experimental high-rises and cultural institutions on the bay, the built environment offers a way to read how Miami negotiates climate, economy, and everyday life.

Over the past century, the city has grown through successive layers of development that remain visible in its streets and skylines. The streamlined geometry and pastel colors of the historic Art Deco District coexist with the exuberant forms of Miami Modern (MiMo) motels and postwar infrastructure along Biscayne Boulevard. Downtown and Brickell have transformed from low-rise business districts into dense clusters of residential and office towers, many designed by international firms working alongside local practices. At the same time, neighborhoods such as Little Havana, Allapattah, and Wynwood reveal how diasporic communities, industrial heritage, and creative industries occupy and adapt existing fabrics, often in contrast with the image-driven waterfront.
