Complete renovation of a flat at Eixample neighborhood in Barcelona. We find a floor that still retained the original layout, with a lot of circulation in corridors, a single bathroom divided into areas with WC and bathroom area and very small rooms including the kitchen. During the renovation almost all the existing partitions were demolished to make a new distribution, gaining all the surface that was lost in the corridors and obtaining a three-room apartment, living room integrable to one of the rooms, two complete bathrooms and a kitchen-dining room continues to the living room and to an intermediate space, which connects all the rooms, with a flexible use of union between the different activities of the house.
