This antique 120-m2 apartment located on Avenida Principe de Asturias, in the emblematic Gracia neighbourhood of Barcelona, has undergone a comprehensive reform that lasted 4 months and that included changes in systems (electricity, gas, water, heating and air conditioning), masonry, interior and exterior carpentry and finishes (parquet, paint, etc). The project has been led by José Antonio Hernández (supervisor) and José Luis Felices (foreman) and designed by Isabel Aguadé Vila (interior designer) and Josep Segarra (construction management). With this reform the apartment gained space, luminosity and functionality.
