Earlier this month, I stepped into a room at the Design Offices on Brienner Strasse in Munich and found something unexpected: tables covered in Lego bricks, buckets labeled “Play is the new serious”, and a group of professionals—my colleagues from Dalux and others—ready to think with their hands.

It was a Lego Serious Play workshop. And yes, it was serious. But not in the way we often define that word in professional settings.

This wasn’t about fun for the sake of it. It was about unlocking perspectives, surfacing unspoken assumptions, and solving complex problems from new angles.

If you’ve never heard of Lego Serious Play, here’s the TL;DR: Lego Serious Play is a structured methodology that uses Lego bricks as a medium for reflection, communication, and shared understanding. Participants are asked to build models in response to strategic questions. Then, through storytelling, each person explains what their model represents.

The bricks become metaphors. The models become dialogue.

In one of our exercises (shown below), we were asked to combine individual models into a larger, collective one. The goal? Reflect how our individual perspectives connect into a shared vision.

You could feel the shift in the room. People slowed down. Listened more. Took their time to understand not just what someone had built—but why.

And the result? A beautifully chaotic, deeply symbolic structure built by a room full of people who had started the session as strangers.

This is a shift in mindset – from Tasks to Mastery. Simon Sinek often draws a powerful distinction between those who focus on simply completing tasks and those who are driven by mastering their craft. This workshop embodied that idea.

We weren’t checking boxes. We were exploring the why behind the what.

It reminded me how easy it is—especially in high-pressure industries like AECO—to fall into a rhythm of delivery without depth. Serious Play offered the opposite: a moment to slow down, reflect, and re-center on what truly matters.

Here’s what stood out:

• Everyone contributes. Hierarchies flatten when every voice is heard.
• Problem solving becomes shared—not assigned.
• Stories, not just specs, guide understanding.
• Mastery starts with curiosity—not urgency.

This workshop wasn’t about escaping work. It was about approaching it more meaningfully.

If you read this far you are asking now most likely yourself, How the AECO industry can learn from Serious Play thinking?

While Lego bricks might not appear on a construction site anytime soon, the mindset we practiced in that room is exactly what AECO needs more of.

What if kickoff meetings began with co-created 3D BIM odels rather than presentations?
What if stakeholder workshops emphasized shared understanding before scope definition?
What if project closeouts included reflection on process and people—not just delivery metrics?

In a field where digital tools and project complexity are growing, alignment has never been more critical. And alignment isn’t built by accident—it’s designed, nurtured, and, yes, sometimes played into existence.

The Shift AECO Needs: From Old Way to New Way

The workshop reminded me that clarity and creativity aren’t mutually exclusive. We can be strategic and curious. Focused and playful. Serious and human.

In AECO, that mindset might just be the foundation we need to build better—together.

Have you ever taken a similar approach in problem solving or team building? How did it shape your impact?
