In Japan, the Comprehensive Design System was established in 1970 to secure public open spaces in response to urban development and population concentration. Since the 1990s, there has been a surge in the construction of high-rise residential buildings applying the Comprehensive Design System. This study aims public open spaces in high-rise residential buildings under the Comprehensive Design System, focusing on sightline openings and composition in comparison to other building uses. By extracting the elements and patterns of composition, this research provides a reference for creating standards for public open spaces, aiming to improve their quality. This study intends to contribute to the development of public open spaces under the Comprehensive Design System.
