In today's episode of the Build Show, Matt visits Whit Smith, Principal Engineer at Smith Structural Engineers, to tour his personal family home under construction on a ranch outside Austin, Texas. Whit walks us through his innovative approach to “monopoly framing” and how a fully integrated air and water barrier—extending continuously from the foundation to the roof—creates a durable, energy-efficient envelope. From CMU parapet walls designed for longevity, to carefully detailed rain screen assemblies, liquid flashing strategies, and advanced roof insulation concepts, Whit blends engineering precision with practical building science. Along the way, Matt and Whit dive into real-world lessons on air sealing, insulation continuity, and moisture management that every builder can learn from. This episode is packed with insights on designing and building homes to stand the test of time. Huge thanks to our episode sponsor, Huber.
