The building, designed by noted Catalan Modernisme architect Antoni Gaudí, has been declared a Spanish Cultural Asset of National Interest.

[1] At the corners of the façade, there are brick pinnacles with a helical column culminating in the four-armed cross, typical of Gaudí's works, and with ceramic shields with various defining symbols of the Teresian order: the crowned Mount Carmel.

On the top floor, a succession of arches (alternating open and blind) form a large frieze that crowns the whole, which is superimposed on the roof railing which is combined with a kind of merlet.

Gaudí used the parabolic arch as an ideal construction element, capable of supporting high weights by means of thin profiles.

[1] Gaudí designed the building for the convent and school of the Teresians on a small budget, which together with the austerity of the religious order determined that the work was rather unpretentious; in this way, the simplicity of the internal structures is reflected on the outside, which is not decorated with any kind of polychromy.

Arguing that brick was not expensive, and that there was not much difference in the cost of placing the pieces one way or another, Gaudí created decorative elements where possible.
