Partnership
- Steffen Lehmann and Igor Peraza both met when they worked together from 1990 to 1993 in Tokyo, at the studio of Pritzker-Prize winner Arata Isozaki, and since then have been practicing and teaching globally for the last 30 years.
- In over 100 projects - through our built works - and in over 20 published books, we share insights into how architecture and urban design can make people healthier and happier. It is a thinking and approach to design that we apply to all projects.
- Our work is research-informed and the mission is to create the world’s most sustainable urban design and architecture.
- To best make use of our immense international experience, we follow four principles to creating a successful and resilient architecture culture: collaboration and teamwork, leadership in sustainable design, integration of research, and diversification of project types and places.
