Matt launches a brand-new Build Original Series®, Build Across America, far away from his home base in Austin, TX . Hop on a plane to Mitchell, SD—where spring feels like winter and the wind never stops—for the first stop on Matt’s journey to build better from sea to shining sea. He’s joined by builder Josh Stange and architect Steve Baczek to explore one of the most advanced residential wall assemblies in the country. Designed to perform in extreme cold and high winds, this home features a unique double-wall system with a centered air barrier, the U.S. debut of SIGA’s Myvest 700 WRB, and other cutting-edge materials like the ZIP System and InSoFast X-brackets.

The team discusses blower door testing, ambitious airtightness targets, air sealing details, basement insulation, and even a concrete safe room. Mechanical planning is front and center with Zehnder ERVs, spray foam strategies, and smart sheathing layouts. Whether you're a builder, designer, or homeowner, this episode offers real-world lessons in building airtight, resilient, and comfortable homes built to thrive in punishing climates.
