Mobility + Place (Part 2): Design for the Desert with Ben Ayers and Hannah Hackathorn

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.

Key Moments in This Episode

01:41 – Meet the Guests
Benjamin Ayers and Hannah Hackathorn introduce their roles at Mancini and discuss how architecture and interiors come together in the firm’s Phoenix office leadership.

03:33 – Phoenix’s Growth Pressures
The conversation begins with the realities shaping design in Phoenix, including rapid population growth, infrastructure strain, construction costs, and climate pressures.

06:18 – What “Mobility + Place” Means in the Desert
Ayers and Hackathorn explain how desert mobility is tied to comfort, transitions, and the challenge of moving through a car-centric city in extreme heat.

09:30 – Thermal Comfort as a Design Strategy
The guests break down thermal comfort in practice, emphasizing shade, building orientation, airflow, and layered passive strategies before mechanical systems ever come into play.

13:35 – Landscape, Microclimates, and the Urban Heat Problem
Ayers explores how landscape can soften Phoenix’s hardscape, create cooler microclimates, and help counteract the thermal mass of asphalt and concrete.

15:33 – Why Water Strategy Is Design Strategy
Water conservation becomes a central theme as the discussion turns to low-water landscapes, efficient fixtures, condensate reuse, and why water awareness must be built into design from the start.

20:13 – Selling Sustainability Through Value, Not Optics
Hackathorn and Ayers discuss how client conversations have evolved, with more focus on long-term ROI, operational performance, and true value rather than plaques or greenwashing.

29:08 – Moving Beyond Superficial Desert Aesthetics
The episode examines regional character in Phoenix and argues for a deeper definition of place—one shaped by climate, culture, economics, local conditions, and community needs.

34:19 – Mixed-Use, Density, and Community Opportunity
Hackathorn and Ayers highlight mixed-use development, walkability, and district-scale thinking as major opportunities for making Phoenix more livable and less car-dependent.

35:44 – The Promise of Adaptive Reuse
Both guests share their enthusiasm for adaptive reuse and discuss why existing buildings, with all their quirks and constraints, can lead to more creative and sustainable design outcomes.

40:46 – What Thriving Hot-Climate Cities Will Do Differently
Looking ahead, the conversation shifts to the next decade: net-positive infrastructure, smarter land use, district-scale resilience, and more intelligent material and building strategies.

44:49 – Desert Lessons for the Rest of the Country
In the closing discussion, Ayers and Hackathorn reflect on what architects and building owners outside the Southwest can learn now from designing in Arizona, especially as climate extremes become a national concern.

47:27 – Designing for the Extreme Future
The episode ends with a broader takeaway: Phoenix may be an extreme case today, but its design challenges offer an early preview of the resilience thinking other regions will soon need.
