In this ICYMI (In Case You Missed It) article-read episode of I Hear Design, we explore “microbiome architecture,” a next-step evolution of biophilic design that intentionally integrates plants and their microbiomes into commercial and institutional interiors. Based on the article by Rose Morrison published on the interiors+sources website, you’ll hear how plant systems can be designed to support indoor air quality, occupant well-being, and sustainability goals, as well as a practical framework for integrating living walls, soil-based planting media, low-tox materials, multisensory accessibility, and HVAC collaboration.

We also unpack real-world hurdles such as scientific uncertainty, maintenance demands, and upfront cost, and discuss how design teams can minimize risks of adoption through early cross-disciplinary partnerships, pilot installations, and performance tracking. The episode includes a case study spotlight on Phipps Conservatory’s Center for Sustainable Landscapes and closes with a roadmap for firms ready to move from “plants as décor” to living systems as measurable building infrastructure.
