The book *Architecture Competition Annual 2026* (ACA) features our “Twins in the Park” project in Düsseldorf in the “Winner” section. With our concept for transforming an office building into two independent residential buildings—Twin I and Twin II—we were able to win the ideas competition.

“Transformation as an attitude: What remains is more than the sum of architectural measures. ‘Twins in the Park’ stands for an attitude: openness instead of separation, multifunctionality instead of monofunctionality, sustainability through transformation. By cutting away, breaking open, and reconnecting, the project creates not only new housing but also a symbolic and tangible act of renewal—a step toward a city that evolves by reinterpreting what already exists.”

The bilingual publication “Architecture Competition Annual 2026,” featuring texts in English and Korean, is published once a year and showcases projects that have successfully emerged from architectural competitions.
