203: Interdisciplinary by Design: How FIFTEEN Builds with Purpose

How can architecture firms move beyond the traditional consultant model to foster truly deep, interdisciplinary collaboration? This week, we welcome Ximena Valle, founder of the Philadelphia-based architecture firm FIFTEEN, and one of her longtime collaborators, Mikael Avery. Ximena founded FIFTEEN to address the gaps she observed in the profession, from talent leaving the industry to a disconnect between designers and end-users. Inspired by her experience on a multi-disciplinary archaeological dig where geologists, mythologists, and chemists worked together to solve a complex problem, she built her firm around a "Collaborator Network."This intentional shift in language, from "consultant" to "collaborator", reflects a profound difference in process. Mikael Avery, whose background spans architecture, landscape architecture, and occupational therapy, is a prime example of the unique expertise FIFTEEN brings to the table. Collaborators are not just brought in for a "nugget of information"; they are integrated into the team from the earliest visioning sessions, contributing to a holistic process where the solution emerges from the group dynamic.Ximena and Mikael share how this model has transformed projects, turning a public space design into a community incubator for startups and workforce development, and evolving a healthcare facility presentation into a fully experiential workshop co-designed with the client. They also discuss the practical challenges of this approach, from creating new financial models to educating clients on the value of a truly integrated team. “The more voices we can get in the room that will misinterpret what we say, if you will, the more opportunities we have to have these ideas bubble up. That is the most exciting part about design… when it doesn’t come from one person, but it comes from the conversation around something. And then all of a sudden, wait, that’s actually the answer right there. It didn’t come from me. It didn’t come from you. It came from the process.” - Mikael AveryThis episode concludes with a reminder that meaningful innovation in architecture doesn’t come from sticking to traditional roles, it comes from rethinking the process entirely. Ximena and Mikael leave us with a clear call to action: open the door, invite in new voices, and trust the collaborative process. Whether you’re leading a firm or just starting out, the future of design lies in embracing complexity together.Guests:Ximena Valle is the founder of Fifteen, a Philadelphia-based architecture firm that is redefining collaboration in practice.
