The ILERNA Barcelona project involves the change of use and legalisation of a residential building for educational use, as well as carrying out works for its connection with the building located at Calle Lepant 410 and the implementation of activities in part of the complex, while maintaining the established use in the rest of the building. Situated at Calle Llorens i Barba 4 and Calle Lepant 410-414, in the Horta-Guinardó district, Barcelona, this project is promoted by IDILIA FOODS S.L. With an awarded budget of 2.1 million euros and a completion period of 4 months, architects Francisco Rodríguez Pavón de la Borbolla and María del Carmen Serrano Peinado are responsible for the design and site management of the project. This intervention transforms the residential building into a modern and functional educational space, efficiently connecting it with the adjacent building on Calle Lepant, while respecting and maintaining the original use in other parts of the complex.
