ABSTRACT
ABSTRACT: Since the second half of the19th century, as a solution for the needs of the wealthy bourgeois society for a clean, attractive and comfortable town, Spanish cities were forced to grow outside the city walls, thus creating extensions. Industrialization in turn caused a massive influx of immigrants from rural areas who demanded affordable housing. However, speculation had excessively driven up land prices of the extensions. In Seville, however, the city grew mostly inward, there were new alignments, interior plots were built and the urban grid was filled. Nevertheless, this phenomenon was not observed before the second decade of the 20th century when the population undertook a major quantum leap. The population increase was due to the soaring of rural immigration to the city, as well as to the preparation for the Latin American Exhibition of 1929, which required additional labor.
