The concept of 'emptiness' has evolved and transformed into various terms such as jungjeong, madang, atrium, corridor, and square-depending on individual interpretations and practices. In today's context, the architectural idea of 'emptiness' might seem like clichéd, dull, and repetitive. Nonetheless, we have deliberately termed it 'empty space,' as we believe the concept of 'emptiness' carries significant value and remains essential to our architectural philosophy. In an era dominated by functionalism, we are taking a somewhat explicit stance against the prevailing norms. We believe that the fundamental characteristics a building's space [空間] should embody are indeterminacy, uncertainty, openness, and variability. In our approach to space [空間], we do not focus solely on how it functions, operates, or what it should be filled with, which are typically planned and pre-determined narratives. Instead, we first step back from such phenomena and consider how to scatter them, introduce unpredictable situations, and contemplate what to leave empty. We also focus on how to organize and structure these gaps or Yeo-back [餘白] (literally "remaining white," a term used to refer to the aesthetic and conceptual value of emptiness). Based on this, we engage in various experiments and work to enrich human life and society.
