Caracas Urban Plan and Buenos Aires Palacio Bosch Showcase Early 20th‑Century Latin American Architecture

In Caracas, the 1939 Plan Rotival marked a turning point in the city’s eastward expansion, laying the groundwork for the later Plano Regulador y de Zonificación of 1951 and the 1953 zoning ordinance. The plans aimed to replace the fragmented, automobile‑driven growth of the 1930s with an integrated network of arterial roads and regulated urban zones, reshaping the historic centre of Venezuela’s capital.

In Buenos Aires, the Palacio Bosch—designed in Paris by René Sergent and built for diplomat Ernesto Bosch in the early 1900s—stands as a refined example of French‑inspired elite housing. Positioned on Avenida del Libertador opposite Parque 3 de Febrero, the residence originally enjoyed expansive gardens and a ceremonial approach, reflecting the aristocratic urban vision of a rapidly modernising Argentina.

Both works illustrate how early‑20th‑century planning and architecture in Latin America combined European design principles with local aspirations, leaving a lasting heritage in the urban fabric of Caracas and Buenos Aires.
