800,000 Homes in God's Backyard? Building Code Battles, and the Future of Sustainable Cities Rises in Greece

The biggest housing innovations aren't coming from where you'd expect. This week, we explore the surprising ideas, policy debates, and breakthrough communities that could reshape the way we build—and live—for decades to come. 

Churches across the country own millions of acres of land, and a growing movement known as "Yes In God's Backyard," or YIGBY, aims to make it easier to transform this land into much-needed housing. It sounds simple enough, but as you'll hear in this week's episode, the idea raises complex questions about zoning, neighborhood character, property values, and the future role of faith-based organizations in solving one of America's biggest challenges.

Housing policy remains front and center as we also examine Congress' newly passed 21st Century ROAD to Housing Act and why some experts say it falls far short of addressing the structural issues driving affordability. Then we head to Maryland, where a heated battle over building energy codes highlights a larger debate playing out nationwide: Is affordable housing defined by lower construction costs today, or lower utility bills and better building performance over the life of a home? With states increasingly taking different approaches, where you live may have more influence than ever on the homes being built around you.

Then it's off to Greece, where one of the world's most ambitious sustainable developments continues to take shape. Built on the site of a former international airport, The Ellinikon is redefining what resilient, walkable communities can become. We also visit Florida's Babcock Ranch, where a new resilience accelerator aims to turn bold ideas into real-world solutions for stronger, safer communities.

The second half of this week's show shifts indoors, exploring a question that feels increasingly relevant: Could healthy indoor air become the next luxury amenity? As wildfire smoke, extreme heat, and outdoor pollution become more common, we look at why clean indoor air is emerging as one of the most valuable features a home can offer—and share practical steps homeowners can take to protect themselves during smoke events.

You'll also discover why heavy timber may deserve far more attention than it receives, not just for its beauty and sustainability, but for its surprising thermal performance and ability to improve indoor comfort. We wrap up with a smart cooling tip featuring Hunter's newest ENERGY STAR outdoor ceiling fan, plus some exciting news from the Green Builder Media team as VISION House Asheville earns national recognition in Forbes.

Whether you're a builder, architect, developer, policymaker, or simply someone who cares about the future of housing, this week's episode is packed with ideas that challenge conventional thinking and showcase what's possible when innovation meets the built environment.
