Given its long historical evolution and the various refurbishments the building has undergone, its façades present markedly different solutions. The wing facing the sea, entirely rebuilt by Adolf Florensa i Ferrer in the 1920s, displays a monumental façade in a classical language with neo-Baroque reminiscences, rather distant from Catalan constructive tradition.
This façade is organised horizontally into three registers and vertically into five bays, arranged along an axial symmetry centred on the main entrance. The lower register consists of a grand portico of semicircular arches, with pilasters and spandrels formed of rusticated ashlar masonry. These arches contain the rectangular windows of the ground floor and the balconies of the first floor, finished with segmental moulded arches and enclosed by cast-iron railings with gilded brass finials.
This base also includes two secondary lintelled entrances and, on the axis of symmetry, the main portal, formed by a tall semicircular arch. Each of these doorways features finely crafted hardwood doors with gilded bronze fittings in the form of spearheads, as well as shields bearing the arms of Spain.
The main entrance, projecting slightly from the plane of the façade, acts as a base for two pairs of Tuscan columns that flank the large central balcony in the second horizontal register. This balcony consists of a wide-span arch supported by Corinthian pilasters, with sculpted triumphal motifs in the spandrels.
The second register contains the two central floors, articulated through an imposing continuous colonnade of monumental Tuscan pilasters supporting a Doric entablature decorated with triglyphs and metopes. The piano nobile is expressed at this level through balconies with stone balustrades, framed by mouldings and crowned with alternating triangular and semicircular pediments.
The upper floor opens to the exterior through balconies with stone slabs, framed by moulded surrounds and flat relieving arches in relief, resting on a stone slab with cast-iron railings finished with gilded brass spheres.
Above the entablature rises the third and final register, corresponding to the attic. This level is rhythmically articulated by pairs of rusticated pilasters framing the windows, whose jambs are moulded and lintels decorated with shell motifs. Above the attic cornice rests the balustrade enclosing the roof terrace.
The attic most clearly expresses the composition of symmetrical vertical volumes. At its centre, the main entrance is crowned by a large coat of arms of Spain, flanked by semi-columns and Corinthian pilasters supporting a triangular pediment topped with pinnacles. On either side of this heraldic composition, two male figures represent Hercules and Scipio.
At both ends of the façade, the attic contains two cubic towers, each face articulated by Corinthian pilasters and triangular pediments topped with pinnacles. These towers open to the exterior through a large window and an oculus beneath a semicircular arch, whose spandrels are sculpted with triumphal motifs.
