Expertise

Architects, engineers, researchers and inventors

ZJA is an architectural studio with an inventor's mentality. We design from the perspective of making. The structural and spatial creation, problem-solving, and design all go hand in hand for us. In the quest for the best combination of technology and aesthetics, sustainability and innovative technologies, such as parametric design, are integral parts of our design process.

Computational design

One of our founders used to joke that he was the first architect to own a computer, although that claim may be debatable. As early adopters who have continued to evolve, we confidently consider ourselves specialists in computational design.
