The Gastizar building, just like the Donosti (also in the Orinoco Avenue), collects much of the residential spirit that characterized «Las Mercedes» for decades. Its name refers to the old tower of a manor in Ustariz, a town of the Basque country. Even though its construction date matches that of the Donosti, this building denotes a clear evolution of the Basque architectural style. Gastizar joins the eclectic search that Miguel Salvador materialized in 1950 with the project for the clubhouse of the Basque Center of Caracas. Without losing the «large house» ap-pearance, the differences that are introduced in relation to the Donosti building are quite interesting. In the Gastizar, unlike the Donos­ti, a greater sense of expressiveness and dynamism in the main faced is appealed to, varying in the proportions of the fillings, modifying the use of materials as ornaments, highlighting its central body vertically and playing with the layout of the ceiling, without altering too much the holes within the absolute-ly symmetrical approach that governs its composition. The dimensions of the rectangular ground and the disposi-tion of the services in the distribution of the apartments are concentrated around a courtyard that allows for natural ventilation. The great state in which it is found makes the building one of the exceptional marks of the neo-Basque architecture of Caracas.
