Building Plans Need Better Grammar with John Straube

John Straube has spent a career breaking buildings on purpose and investigating the ones that failed by mistake. Test huts exist so that when the experiment goes wrong, nobody gets hurt. The forensic work is the other half. As John puts it, the experiments he could never ethically run himself get run for him, by architects and builders, on real projects. In this conversation on Build It Forward, recorded in the Building Science Corporation Test Hut at Summer Camp 2026, Nick Falkoff sits down with John, a building scientist and engineer who teaches at the University of Waterloo and consults through RDH. John argues that most builders and designers never see enough failures to calibrate their own sense of risk, which is why they can walk along the edge of a canyon in the dark without knowing it. The conversation covers how he teaches people to read a detail, why a wall schedule should list what each layer does and not just what it is, the difference between an aesthetic mock-up and a performance mock-up, and why he thinks a code compliant building is the worst building you can legally build. It closes on what makes a great building scientist, which turns out to have less to do with physics than with actually cutting wood and pouring concrete yourself.
