The circulation of the Colegio Nacional de Arquitectos building is through a double-loaded corridor.
It was one of the first curtain walls to be used in Cuba.
 The building consists of a semi-basement and two floors that houses offices, a library, recreation rooms, an auditorium, and a large spiral staircase that forms a large space on three levels which is illuminated by natural light from three panels of glass blocks.
It has several outdoor porches.
On the outside, coral stone and green Cuban marble are used.
The main part of the building (auditorium) is covered by a gable roof, the rest of the building has a flat roof.
