Relationships between important families who were part of the bourgeoisie in Barcelona during the late 19^th century played a significant role in the establishment of modern architectural styles and practices. Complex interrelationships existed during this time between significant figures of various disciplines and influential families. Architects who were at the forefront of modern architecture in Barcelona at this time include Martorell, Gaudi, and Montaner, each of whom had ties to Antonio Lopez’ project for his grand mansion and pantheon. Eusebi Guell is related to the Lopez family through marriage, and the architects maintain close ties and work relationships with them. The architectural works which were designed and built for these families were no doubt influenced by these complex interrelationships, especially since politics and social influence were directly correlated with the bourgeoisie lifestyle. This paper explores the connections which existed between the Spanish bourgeoisie in an attempt to prove that the personal influences of close contact and interaction between client and architect affected designs in a manner which helped shape the Spanish modern style which would emerge in Barcelona in the 20^th century.

Various academic journals and books have been written about Gaudi’s career, which include communications between Guell. Primary resources written by historians exist on the topics of the bourgeoisie in Barcelona.

This paper will consult direct accounts of the important figures discussed as well as research which studies their relationships and the architecture which pertains to them. Specific sources include articles published in academic journals, interviews, and bibliographical accounts.
