Las Casas de Enfrente were conceived as a fish market, that is, as a public building for commercial services, although today it is in private hands. The façade has a horizontal structure of three bodies: the first -formed by a gallery of seven arches on pillars-, follows the typical structure of the arcade, present in a large number of Spanish public squares.

The main floor shows its openings with balconies and shields at the ends, while the upper floor is transformed into a gallery with semicircular arches, larger than those of the City Hall.
