Semiotics in architecture of public spaces: contemporary city-centers; case of Bangalore, India

Abstract This paper investigates the public space architecture in urban centers of contemporary cities. Through time cities evolve with a certain traditional profile either spontaneous or planned; correspondingly, urban spaces emerge responding to the current developments, community aspirations, and architectural influences of the era. The study adopts a research methodology of triangulation involving review of theoretical derivatives, legislations for urban aesthetics, and conducting visual surveys of urbanscapes. Three fundamental theories are explored-‘Semiotics/Semiology’ by Saussure (1916) and Peirce (1902), ‘Duck and decorated shed’ by Robert Venturi (1972) and ‘Urban semiotics’ by Kevin Lynch (1960). The premise is investigated with the case of Bangalore (also, Bengaluru) in India; a city which has a rich historical profile while also being one of the progressive cities, resulting in transitions in its urbanscapes profile and existence of two distinct city cores, old and the new. This analysis is ensued by adopting comparative analysis of façades investigated in these two Central Business Districts, with a ‘Façade grid’ assessment methodology leading to interpretation of varying semiotics in both scenarios. The surveys conducted reveal an interesting semiology in the older and newer nodes reflecting intense objectives of commercial architecture and leads to formulation of a strategic proposal framework for façade architecture and management to reconnect to the use-experiential factors in urban centers.
