This week, we talk with Thaddeus Lee, a Play Inventor at LEGO’s Creative Play Lab. Have you ever wondered how aesthetics emerge from culture? What does empathy-driven design look like? How do you balance bold ideas with business reality? Whether you're establishing your design values or wondering how to turn ideas into products, this episode is for you! Reimagining Design and Redefining Value “Design is optimistic—it’s the belief that you can do something just a little better.” Thaddeus’ journey from architecture studios at Yale and MIT to now leading innovation at LEGO’s Creative Play Lab reflects this philosophy. For him, design isn’t just about the final product, nor is it limited to making things look good. Instead, design is a form of creative problem solving, a way of thinking that can be applied to buildings, toys, businesses, and even careers. Throughout his journey, Thaddeus has used design to question established narratives, including the narrow definitions of success that often shape creative fields. “It doesn’t matter what kind of business you’re going for—nonprofit, B2B, or direct-to-consumer—there’s always some kind of value you’re trying to define with design.” In other words, design is not just about aesthetics. More so, it’s about articulating and delivering value. And yet, “value” itself is not a fixed concept. Thaddeus speaks to the importance of understanding both internal values (what you personally care about as a designer) and external values (what your audience, collaborators, or employer prioritizes). “Everybody’s going to have an opinion on whether your design is good. As long as you know what you value as a designer and you’re achieving those goals, that’s a good place to start.” This self-awareness not only grounds your practice, but also helps you choose opportunities that align with your beliefs and challenge you to grow. In some cases, you may need to adapt your ideas to fit the business or organizational context you’re working in. At the LEGO Group, for instance, the role of designers in the Creative Play Lab is to help prove that a new idea is playful, but also meaningful and viable. “The challenge,” Thaddeus says, “is to not just pitch the vision, but figure out how to get there—whether you have $20,000 or a million.” To reimagine design, then, is also to reimagine value not as a singular truth, but as a dynamic negotiation between what matters to you and what matters to the world. Aesthetics as By-Product We also discussed the value of aesthetics, and its importance in the design field. “Aesthetic is not an end in itself but a by-product of good design,” Thaddeus explains. His time at Yale emphasized formal aesthetics, while MIT’s culture focused on experimentation: “MIT’s aesthetic isn’t curated. It emerges from the culture. It’s incredibly brainy, incredibly experimental, and not really conscious about the aesthetic it produces.” This view liberates designers from obsessing over style. Instead, Thaddeus believes in focusing on solving meaningful problems. “Hopefully you’re thinking about the user, sustainability, computational tools, other ways of doing things.” Aesthetics, he says, will emerge naturally from the rigor of the process. Further, Thaddeus elaborates about defining the value of design. A Human Centered Approach For Thaddeus, design is fundamentally relational. It is not about asserting authority or imposing taste, but about empathy. Good design involves understanding others and offering them a glimpse into your perspective. “You’re not there to dictate what is good design. You’re there to invite people into your world, to let them see why it matters.” This approach guides his work at LEGO, where early-stage prototypes are tested directly with children. Watching how they engage, often with joy, unpredictability, and honesty, offers powerful insight. “There are these incredible moments where I get to put them in front of actual kids and see how they react,” he shares. “The value there is being able to bring joy to a playful moment.” Thaddeus also draws inspiration from Charles and Ray Eames, who treated design as a form of hospitality. Whether through picnics or short films, they believed designers should act as thoughtful hosts, welcoming others into an experience. For Thaddeus, empathy means creating space for others and staying open to the worlds they bring with them. An Actionable Tip We recognize that it’s difficult to translate stories into your own learnings, so beginning with this episode, we will end the accompanying notes an exercise you can try today!Take 10 minutes to write down three things you value most in your design work. These could be principles like clarity, playfulness, social impact, empathy, or experimentation. Then ask yourself: * Are these values showing up in the work you’re doing now? * Do the opportunities you’re pursuing align with them? * Where might you want to recalibrate? This kind of self-check-in is helpful at any stage of your career, especially when you're making a transition, questioning your path, or trying to find your next step.
