The way mankind intervenes at junction of land and sky

Wayne Attoe regarded the way mankind intervenes at the junction of land and sky as one of the meaningful measures of civilization. Following the establishment of cities, the concept of a skyline emerged, denoting the horizon defined by structures constructed by humans. This not only reflects architectural and construction techniques, resource utilization approaches, but also extends to attitudes towards nature, visually capturing urban development and evolution. However, each of these interventions also resides within a topological duality relationship.
Cities like Seoul, which have developed within natural topography, possess a history of urban planning involving height restrictions on buildings to conserve the natural landscapes of mountains. These mountain-bound cities each form unique skylines through a juxtaposition of ridgelines and tall structures, amidst the interplay between urban development and height regulations.So, does the existing height regulation genuinely facilitate an ‘ideal’ skyline? Furthermore, what forms of skylines that protects mountain views while meeting appropriate development capacity or specific goals?
In actuality, there has been insufficient simulation to satisfactorily address the questions posed. This endeavor introduces optimization as a proposition to establish the foundation for such discussions. It is not an endeavor to carve out a highly rationalized single urban model or to locate deadlocks in discourse. It is an attempt to explore the potentialities of diverse urban forms and enable adaptable compromises. Hence, it suggests examining the trajectories drawn by the multitude of forms generated within the optimization process, rather than extracting optimal model. Through complementing qualitative assessments or accommodating viewpoints, or by engaging in processes like aligning with alternative plans, this methodology can unearth better points of deviation.
