What does it mean to design for place in a desert city shaped by rapid growth, rising heat, and shifting expectations around how people live and move? In Part 2 of I Hear Design’s Mobility + Place mini-series, Robert Nieminen speaks with Hannah Hackathorn and Benjamin Ayers of Mancini’s Phoenix office about the realities of designing in and for the desert. In this conversation, we explore how architects and designers are responding to extreme heat with layered strategies for shade, landscape, airflow, and thermal comfort, while also rethinking water use, sustainability, and the role of regional identity in a fast-evolving metro area. Hackathorn and Ayers discuss why climate-responsive design must begin with fundamentals like building orientation, form, and site planning; how outdoor transitions can become more humane and usable; and why authentic design for place goes beyond desert aesthetics to reflect culture, community, and long-term livability. They also look at the promise of mixed-use development, adaptive reuse, and greater density as Phoenix continues to grow. In this episode, you'll discover: How designing for extreme heat goes beyond HVAC to include shade, building orientation, airflow, landscape, and transitional spaces between indoors and outdoors. Why thermal comfort in desert environments is as much about human experience and movement as it is about technical performance. How water awareness shapes architecture through landscape choices, low-water fixtures, and the idea that in the desert, water strategy is design strategy. Why authentic regional design should respond to climate, culture, community, and construction realities—not just rely on stereotypical desert aesthetics. What fast-growing cities like Phoenix can teach designers everywhere about resilience, density, mixed-use development, and creating more walkable, livable communities. How sustainability conversations with clients are shifting from certification and image toward long-term value, performance, and return on investment. Why adaptive reuse and district-scale thinking may play a bigger role in shaping the future of desert cities than standalone buildings alone.
