Hyunsik Yoon graduated from the University of the Arts London and UCL Bartlett School of Architecture. He gained practical experience at Bjarke Ingels Group, Benoy, and BCHO, working in London, New York, Hong Kong, and Seoul. His portfolio includes high-profile projects such as the Google Campus headquarters in the United States and the large-scale Lotte Hanoi Mall development. Beyond architecture, he has actively explored the fields of art and humanities, participating in public art competitions and co-exhibiting at the Seoul Biennale of Architecture and Urbanism.

Chanyong Lee graduated from Hongik University and developed his professional skills at BCHO, engaging in diverse projects for high-profile clients across commercial, residential, and premium office sectors. His expertise spans from conceptual design to detailed design and construction supervision, with a strong focus on reinterpreting the artistic value of architecture and space in innovative ways.

In 2021, Hyunsik Yoon and Chanyong Lee co-founded TOOOC (Woowawoo) with a vision that goes beyond simply constructing spaces, pursuing architecture with stories that connect people, nature, cities, and history. We seek balance and depth that quietly blend into life rather than superficial display, while embracing bold experimentation and interpretation. By honoring context yet opening new possibilities, we aim for a flexible approach that spans from intimate homes to symbolic landmarks.
