This study examines how the egalitarian ideas that Ildefons Cerdà intended to realize through Barcelona's urban expansion plan were organically expressed and implemented through the grid system. The main conclusions drawn through the study are as follows. First, Cerdà proposed an urban expansion plan using an organic grid system to solve the overcrowded urban problem and improve the living environment of the working class. The grid system was created as a fundamental structure and language for its expansion for its organic change and sustainable development and growth beyond the application of the existing grid patterns for geometric or efficient urban design. Second, Cerdà's grid system acts as an system and network that enables functional distribution and equal access across the city. It secures equal lighting and ventilation through the arrangement of housing and road design in the city, and connects infrastructure facilities and blocks of various sizes and functions so that the entire city can operate like a single network. Third, through the hierarchy of roads and the organic characteristics of the grid system, the mobility of all citizens in the city was increased, and an environment in which public facilities and resources were evenly distributed was created. This was part of an organic plan rather than an efficient or aesthetic design by allowing various shapes to be transformed in consideration of the integration with the old city. Finally, the grid system presented in Cerdà's Barcelona Urban Expansion Plan can be evaluated as a system and network that organically connects and develops overall city functions, not just a geometric and efficient design. This study confirmed that Cerdà's egalitarian ideas were reflected in the basis of this organic grid as an important urban planning tool to secure urban sustainability.
