This chapter delves into a design workflow that embraces the concept of “Harmony in Co-Creation.” Exploring the profound implications of and relationships between quasi-autonomous design and non-autonomous design provides insight into the future of architectural practice. By employing a multidisciplinary approach, the chapter introduces two workflows. The first workflow integrates artificial intelligence (AI) algorithms in the form of search engines and diffusion models to elucidate and enhance students’ understanding of site dynamics and design potential. Meanwhile, the second workflow employs a digital collage methodology, using manually discovered and collected data and a hand-crafted approach to ideation, representation, development, and iteration. The chapter explores projects undertaken in densely populated metropolitan contexts to test these two approaches. Concluding with reflections on the innovative methodologies embedded in the workflow and their potential impact on architectural education, this chapter emphasises the fusion of digital technologies and the representation of physical experiences in shaping innovative architectural solutions. “Harmony in Co-Creation” encourages readers to contemplate the profound implications of quasi-autonomous and non-autonomous design strategies as a natural continuation of foundational methodologies and past technological introductions rather than as an existential threat to the profession.
