Travis discusses how to reduce elevation changes in residential construction to support aging in place. Instead of traditional top-bearing floor systems, he demonstrates how dropping the floor inside the foundation creates level access. This design minimizes stairs at entry points, aiding mobility and long-term accessibility. However, Travis emphasizes that such modifications come with added costs—more concrete, specialized anchors, engineered lumber, and a high number of hangers and fasteners. He encourages thoughtful design for future generations, while cautioning that creating a step-free layout ironically requires many extra construction steps. His final takeaway: fewer obstacles mean more planning and investment up front.
