Among the main components of a smart city, the modern public space plays a vital and core role in the transition towards a friendly lifestyle. However, urban planning and design guidelines in many countries’ practices have radically transformed without cultural preservation purpose. Therefore, it is necessary to design public space with local cultural wisdom demonstrated as renewable criteria considered a sustainable public space solution for smart cities. This may improve places, increasing prosperity and extending expectations of modernization in many cities. (...) This article contributes to cultural preservation dynamism in public spaces. It explores how modernist approaches to planning and design along with cultural features shaped the quality of urban space. This study uses the Banjar culture in Banjarbaru City, Indonesia as a replanned city in a rapidly developing economy, but one where largely unusable public spaces have failed to meet people’s everyday needs and aspirations. The study was performed based on extensive literature reviews, documentary analyses, morphological surveys, photographic and qualitative surveys. In general, the integration of Banjar culture into modern public space provides a better promotion understanding of identity and friendly environmental quality. (shrink)
