By the 1890s the property was purchased by Tirso de Olazábal y Lardizábal, Count of Arbelaiz, and Graziela Zileri del Verme degli Obbizi, Duchess of Cadaval.
Each Villa had a staircase and an independent entrance; the first two (both belonging) to the Olazábal family, had a communication to the main floor by a gallery.
