Vicens, Dolors Giralt i Grífol, sold the house to Dr. Antonio Jover Puig for 45,000 pesetas. Antonio Jover (Barcelona, 1855-1930) was a renowned paediatrician, who had graduated from the University of Barcelona in 1876. He was living in Cuba and worked as a professor at the University of Havana, until the island gained independence and he returned to Spain. Thanks to the fortune he accrued in Ultramar, like other returning emigrants of the time, he was able to acquire Casa Vicens. He represented various Spanish commercial interests in Cuba and, even after its independence, returned to spend time on the island. He was also president of the Casino Español in Havana and the Cercle Català. He settled in Barcelona in 1924, was a councillor of the City Council of Barcelona from 1924 to 1930 and deputy mayor with Darius Rumeu i Freixa, Baron of Viver. In 1908, Dr. Jover sold the house to his brother, José Jover, maintaining usufruct of the property. When he died without issue in 1913, he left it to Ángela González Sánchez, Antonio Jover’s wife. In 1925, Dr. Jover planned an extension of the building with the aim of turning it into his principal residence. For this, he acquired 212.88 m² of land adjacent to the wall shared with the convent, on 18-20 Carrer de les Carolines. He also acquired the land located between the narrow street of Carreró Racó de Sant Gervasi and Avinguda de la Riera de Cassoles, and he was able to have the alleyway declared an unused public thoroughfare, with which he could expand the garden into that area. With this, the property had reached its maximum size of 1,738 m². He approached Gaudí to lead the project to extend the house, but he declined, as he was devoting himself fully to the Sagrada Família at the time. Instead, he recommended one of his protégés, Joan Baptista Serra, who designed the right half of the facade in the style of Gaudí. Joan Baptista Serra de Martínez (Barcelona, 1888-1962) studied at the Barcelona School of Architecture and graduated in 1914. That same year he met Gaudí at the church of Saints Justus and Pastor and they were brought together through their love of music. Eclectic in style, he was influenced by both Modernism and Noucentisme, Classicism and modern European architecture. One of his first works was Casa Cucuruy in Barcelona, which was followed
