OZ is looking for a technical designer with an eye for detail and a heart for building
Are you someone who gets energy from working out smart, sustainable solutions? Do you have an affinity with complex projects and do you want to work on projects that really mean something to the city and its inhabitants? Then we would like to meet you.
Architecture Internship
OZ is seeking Architecture Interns to join our design team, starting April 2026. In this role, you will work on a variety of projects while receiving guidance and mentorship from experienced architects. This position is ideal for motivated and talented architecture students who are eager to gain practical experience in a dynamic and competitive environment.
A New Chapter for OZ
We are excited to introduce our two new partners: Stefan de Koning and Andreas Karavanas. Both teamed up to strengthen our ambition to create sustainable, people-oriented architecture. Stefan and Andreas bring extensive international experience across public and private sectors.
The team of OZ-partners now consists of Chris Zwiers, John Bosch, Oresti Sarafopoulos, Stefan de Koning, Andreas Karavanas, and managing director Marlies Zwols. Together, we unite a range of expertise and cultural insights with a bold spirit and a collaborative approach – ready to shape the next chapter of OZ.
Stefan de Koning
Stefan joins us after two decades as partner at MVRDV, bringing a deeply rooted design vision and proven leadership. His work embraces urban density, accessibility, diversity and playfulness – values that align with our mission. Stefan will lead the development of new design strategies and of multidisciplinary teams, building on our strong position.
“I am aware that architecture can contribute to a livable future. So we have to design inclusive and adaptive in this dynamic and complex world.”
Andreas Karavanas
Andreas brings design excellence and a research-driven approach to OZ following a decade at OMA. His work explores the intersection of architecture and urban conditions, shaping the increasing complexity of architectural typologies. Andreas will develop strategies grounded in research and responsive to urban realities, reinforcing the studio’s commitment to innovative design thinking.
“To me, architecture that is both rooted and future-proof, starts with deep understanding of context, culture and the everyday.”

In the City lies the path to a sustainable future. Looking beyond buildings an inclusive perspective is needed. By intensifying urban nature and social interaction we create thriving places for people.
OZ AND THE CITY
This bookazine presents five perspectives on the city while also highlighting the references, working methods and architectural choices of OZ.
It is a response to the increasing dominance of economic motives in the built environment. Architecture is increasingly becoming a marketing tool and images – especially digital media – are only used to seduce. With this bookazine we want to place our designs in an architectural discourse: we are making an attempt to interpret the development of architecture again from the perspective of spatial experience.
OZ operates in the city from a down-to-earth attitude. Not politico-economic but culturally driven we search for a social relevance that embraces the complexity of life and enriches the environment.
