What does it really take to build homes that are beautiful, efficient, resilient, and responsible?

In this special 100th episode of Home Green Homes, Izumi Tanaka welcomes Steve Glenn, founder and CEO of Plant Prefab, for an in-depth conversation that weaves together architecture, sustainability, entrepreneurship, and climate action.

Steve traces his path from an early love of architecture to founding LivingHomes and later Plant Prefab—companies created to challenge the waste, inefficiency, and environmental impact of conventional construction. He explains what truly sets Plant Prefab apart: customized architectural design, a purpose-built factory capable of both panelized and modular construction, and a mission-driven commitment as a certified B Corp and public benefit corporation.

The conversation also dives into Plant Prefab’s work supporting communities rebuilding after devastating Southern California wildfires, and why prefab construction can offer faster, more predictable, and often more cost-effective rebuilding solutions.

Along the way, Steve addresses common misconceptions about prefab homes, shares what homeowners should prioritize when designing for climate resilience, and reflects on leadership, scaling a values-driven company, and what he hopes the future of housing can become.

This episode is especially relevant for homeowners, home dwellers, architects, builders, developers, and anyone curious about how housing can be part of the climate solution.

Key Takeaways / Listener Highlights

• Prefab ≠ mobile homes: Plant Prefab homes are legally and structurally equivalent to site-built homes and cannot be excluded from zoning, financing, or insurance.
• Energy matters most: Over a home’s lifetime, operational energy use has a bigger climate impact than materials—efficiency and solar should be top priorities.
• Time is money: Faster, parallel construction can significantly reduce carrying costs, rent, and uncertainty—especially important in rebuild scenarios.
• Design and sustainability go together: High-quality architecture and environmental responsibility are not mutually exclusive.
• Rebuilding after disaster is an opportunity: Prefab can help communities recover faster while building more resilient, future-ready homes.
• Mission-driven businesses face real challenges: Scaling sustainably takes persistence, patience, and long-term vision—but the impact compounds over time.
