O-N is an architecture studio committed to an optimistic view of the world, created by a wide angle of design solutions. Based in New York since 2019, we work across the US designing objects, buildings, cities, and environments. Testing, learning, and play are critical to our process. We value immersion in complex problems, often relating to our perceived understandings of space, shape, and context. We are interested in solutions which evoke both the familiar and the strange.

Irene Chung

Irene (she/her) is an interdisciplinary thinker. She co-founded O-N where she focuses on designing thoughtful, caring spaces that support people’s aspirations. On every project, Irene brings her ideology that care and mindfulness for our clients’ goals are key to meaningful design.

Irene’s background in strategy and operations at Data & Society Research Institute (D&S)—an independent, nonprofit research institute that believes that technology policy must be grounded in empirical evidence, account for tech’s real-world impacts, and serve the public—has trained her to challenge assumptions of design solutions and surface underlying shared values that drive intention for impactful design. With that, she is committed to designing spaces that are true to clients’ values, while operating with a sense of playfulness to make rigorous design accessible to a broader community. 

Irene graduated from Fordham University with a B.A. in Anthropology and Psychology.
