This study empirically explores 3d isovists to explore an alternative approach to a 90-meter height cap in Seoul’s historic center. The proposed approach integrates the concept of view shadow cast by existing towers to minimize visual impact and preserve iconic and historic views. The simulation findings indicate that a significant portion, approximately 31 sites or 58.5% of the total, can accommodate taller towers than 90 meters without compromising the integrity of the historic skyline. The study demonstrates the ability to increase the floor area by 74% and up to 137% from existing conditions to revitalize Seoul's historic center.
