The Stella Maris Church stands out for its modern forms in contrast to the classicist architecture that surrounds it. This simplicity is reflected in the ceramic brick without exterior cladding, the metal supporting structure and the profiles of the same material for the carpentry. The building is completely regular and so are the spaces that make it up. The church, which is accessed at one end, under the double choir, has a somewhat elevated altar at the opposite end, leaving a semi-basement chapel underneath it. 

On the main and only volume of the church, with a trussed structure supported by the perimeter supports that are located on the facade and lateral party walls, hang the three levels that make up the convent; the immediate level above the church houses a large and free cloister, and above it the dependencies of the community, to culminate with the cells under the slopes of the roof skirts.
