our story

3DuxDesign is a true family business. Growing up in the Klein household required a good bit of creative thinking and improvising. Every year, holiday gift-giving had one rule: Our mom would say, "The best gifts are made with our hearts, our hands, and any materials already in the house. They are not bought at a store." 

So while millions of holiday shoppers would flock to stores seeking the best Black Friday deals, we would rummage through the recycling bin for interesting  materials and then head into the basement for cardboard boxes to start constructing our gifts. It was truly amazing to watch odds and ends transformed into townhouses, parking garages, pinball machines, Kitty-Kingdoms and Hamster Havens. Yes, even the family pets were involved. We learned physics creating a pulley for an elevator. We learned about electric circuits making a pinball machine. We learned how to work together. And, we learned how to imagine, design and build something for the people that matter to us.

The 3Dux ethos is that the best gift we can give children is an active imagination and the freedom to create. Without pre-set rules and instructions (conspicuously absent from our modeling kits), children will learn to improvise, experiment, fail, reexamine, and succeed. These are the skill sets that will aid them through life challenges. With the 3DuxDesign Architectural Kits we encourage your children to experiment with form, function, creativity and deductive thinking. Our design challenges extend from k4 through middle school and are based on design thinking and engineering concepts with a focus on community, communication, empathy, and creating a sustainable world. 

We challenge kids to learn how good design can make a better future.

Architecture, Design Thinking, and the 3DuxUniversity

Architecture brings open-ended creativity and design thinking to traditional STEM learning. 

We are a team of designers, educators,  architects, engineers, artists and other thought leaders having some serious fun educating the next generation. Our project-based workshops inspire children to define problems, collaboratively explore solutions, create, and reevaluate. 3Dux classes incorporate a wide range of topics including sustainability,  urban planning, and social equity for a more holistic approach to STEM learning.
