In this episode of What the RFI?, host Matt Brennan sits down live at AIA Aspire 2025 in Asheville, NC, with architect Toby Witte of Wittehaus. Known for designing modern, energy-efficient homes across the Carolinas, Toby brings a deep passion for detail, sustainability, and storytelling in architecture.

The conversation traces Toby’s journey from Germany to the U.S., his design philosophy, and how details, from light and shadow to millwork and railings, shape not only buildings but also people’s lives. Together, Matt and Toby explore how trust, collaboration, and client engagement are essential to creating homes that are both deeply personal and environmentally responsible.

They explore topics ranging from the importance of craftsmanship on the job site to healthy home design and air quality to the growing potential of solar energy to make homes self-sufficient. Along the way, Toby shares stories of unique client-driven projects, including designing a home around a baby grand piano, a perfect example of how architecture can tell stories and reflect passions.

Whether you’re an architect, contractor, or homeowner dreaming of your next space, this episode highlights the power of details to transform the way we live.
