For decades, the Arizona Dream was etched into the sun-drenched suburban sprawl—a seemingly infinite grid of single-family homes marching toward the McDowell Mountains. But today, a new silhouette is emerging. The once-dominant horizontal narrative is being rewritten by a crane-dotted horizon along the Camelback Corridor and the high-density hubs of the Southeast Valley.
This is the birth of the “Vertical Valley.” According to the Maricopa Association of Governments Socioeconomic Projections, the Phoenix Metropolitan Statistical Area is bracing for a staggering surge, with population figures expected to climb from approximately 5.1 million in 2023 to 7.5 by 2060. As the physical and regulatory limits of the desert floor tighten, “infill” is no longer a buzzword—it is a necessity. At the center of this transformation is a housing typology that is both highly sought after and frequently misunderstood: the “stacked condo.”
