Buenos Aires Modernism: A Guide to the City's Early Architectural Gems

architecture-design · 2026-09-22

From the mid-1930s to the early 1940s, Buenos Aires experienced a flourishing of modernism characterized by significant urban development and a rich cultural scene, highlighted by a golden era for tango, film, and literature. Architects embraced innovative designs rather than traditional European styles, creating buildings that harmonized with nature and promoted communal living. Among the prominent projects were the Kavanagh building, designed by Luis Sanchez, Ernesto Lagos, and Luis María De La Torre, which stands as South America's tallest reinforced concrete structure, and Casa Bigatti-Forner by Alejo Martínez. Antonio Bonet's Ateliers para Artistas introduced the BKF butterfly chair, while Jorge Ferrari Hardoy and Juan Kurchan's Edificio O'Higgins 2319 provided adaptable apartments. Other key contributions include Eucaliptos by Hardoy and Kurchan, Casa en Calle La Pampa by Wladimiro Acosta, and Teatro Gran Rex by Alberto Prebisch.
