I’m your host, Anastasia Casey, and today, we’re sitting down again with one of the most respected names in the industry—Heidi Caillier. An AD100 designer, Heidi has built a career on reinventing tradition, crafting interiors that feel intimate, layered, and deeply personal. Known for her confident use of pattern, color, and nostalgic elements, she designs spaces that stand the test of time, valuing heirlooms, antiques, and handcrafted details over fleeting trends. But beyond her signature aesthetic, Heidi has also simplified and standardized the business side of interior design—something we’re diving deep into today. I first learned of Heidi’s straight forward approach last October at Design Camp, and the details utterly blew my mind. Heidi’s model of whole home design presentations and flat rate product markup feels refreshingly easy to manage, and all around magical. We’ll explore why she made that decision, how it streamlines client communication, and why presenting an entire home concept at once—instead of breaking it into phases—has transformed her design process. From the systems behind her full-scale presentations to how this approach strengthens client buy-in and decision-making, Heidi is sharing the strategies that make her projects not only beautiful but also incredibly efficient. If you’ve ever struggled with pricing transparency or felt overwhelmed by phased presentations, this episode is packed with insights you won’t want to miss. Don’t forget to tune in to Season 2 Episode 1 to hear our first conversation about Heidi’s signature style after this episode. But for now, let’s get started.
