Abstract

With the rise of multi-layered urban development, elevated walkways have emerged as a key driver in expanding office functions into semi-public spaces accessible to local communities by enhancing pedestrian connectivity within the city and fostering community interaction. However, recent skepticism regarding their effectiveness has led to a decline in new projects. To address this, design strategies that go beyond openness and accessibility—stimulating users’ sensory experiences—are increasingly important. This study examines Taikoo Place in Hong Kong, a recently completed development that effectively enhances the attractiveness of semi-public spaces through elevated walkway integration. Using spatial observation and qualitative analysis, the study analyzes Taikoo Place based on eleven key design features associated with spatial vibrancy, with a focus on spatial attractiveness. The development creates a large-scale semi-public realm that connects previously disconnected buildings via elevated walkways within a compact, high-density urban fabric, and it reinforces inclusivity as public space through a permeable podium that blends interior and exterior into a continuous space. It emphasizes a linear, looped layout to establish a strong sense of place, while offering variety through volumetric, dynamic changes. In particular, it links distinctive indoor and outdoor environments, enabling users to experience a spectrum of spatial conditions. Above all, these qualities collectively demonstrate how Taikoo Place achieves a high level of spatial attractiveness by capitalizing on urban conditions and institutional frameworks conducive to spatial vibrancy and the creation of semi-public spaces. The findings provide practical design insights for the creation of semi-public office spaces connected by elevated walkways and inform strategic planning for office redevelopment and multi-level pedestrian networks in dense urban areas. ©Copyright 2026 Architectural Institute of Korea.
