Casa Pericas is located on the block in the Eixample district bounded by Rambla de Catalunya, Carrer Còrsega and Avinguda Diagonal. Located at the junction of the latter two thoroughfares, it is a residential building with three façades articulated by means of two cylindrical tribunes.
The building consists of a structure on the ground floor, mezzanine, main floor and five upper floors, all covered by a flat, walkable rooftop. Its openings are arranged in five horizontal sections separated by imposts.
The lower section comprises the ground floor and the mezzanine with ashlar stone fittings. The ground floor has a doorway on the right-hand corner of the façade facing the diagonal street, with a framed round-arched doorway closed by an ornate iron door. This entrance leads to a vestibule area and a central light courtyard where the residents' staircase is located. The rest of the openings, corresponding to the commercial area (in this case a bank), are framed by classicist columns.
The second section contains the main floor, where the stone balustrades of the balconies and their sculpted framing stand out.
The third section contains the next four floors, with a wall covered with sgraffito work reminiscent of ashlar stone. There are some panels, also sgraffitoed, with figurative decoration and bucolic themes. The openings have windows and balconies with wrought-iron closures and sgraffito ornamentation on their bases and frames.
The final section comprises a continuous gallery with small windows with semicircular arches crowned by a sgraffito border, all crowned by a powerful eave that overhangs the façade line and the flat roof enclosed by a balustrade.
The two vertical tribunes at the corners give continuity to the façade, avoiding sharp angles. These are reminiscent of German expressionism and are topped by a wavy gable.
