Large building located in La Bonanova neighbourhood. It takes up the end of a narrow block of houses, which means that it has three façades: a large one that faces Ronda General Mitre and two narrower ones on Balmes and Miño Streets. It consists of a ground floor, six floors, an attic and an upper attic set back from the plan of the façade. There is a great contrast between the two corners of the house; the one on Balmes Street has a large, rounded shape reminiscent of a ship, while the one on Miño Street is finished off with an edge, which makes the chamfer between Balmes Street and Ronda del General Mitre take on great prominence and become the main view of the building.

On the ground floor, the openings follow a regular rhythm, and the facing is covered with dark grey stone, except for the lower part of the windows of the Ronda General Mitre, where the stone is light in colour. The transition from the ground floor to the first floor is marked by a brickwork balcony that runs along the three façades. The wall of the six upper floors forms a grid marked by the horizontal axes of the openings and the vertical ones formed by the changes in wall hangings, between exposed work and concrete. In the corners, the wall advances with respect to the plane of the façade and these advances are finished with a rounded balcony, which creates a game of full and empty spaces that gives great plasticity to the façades. The openings are rectangular and stand out in the round chamfer where there are three windows, per floor, separated by a thin smooth column that give the impression of being a large sash window.

The attic takes up less space than the lower floors which means that there are garden terraces. The wall on this level is all concrete, breaking the vertical axes of brick, and opening rectangular windows and two portholes in the façade of the Ronda General Mitre. At the corner with Balmes Street, the façade recedes a few metres and the wall also has a rounded shape but with a sharper angle. This whole level is crowned by a plain molding and the closing wall of the roof. The attic is not visible from the street.

Building commissioned by Lluís Jara Urbano, who was chief engineer of the Barcelona City Council. During the 1940s he was responsible for planning the route of the subway, and in the 1950s for the urban sewer system.
