The Kavanagh Building, an iconic skyscraper in Buenos Aires, Argentina, was designed in 1934 by architects Gregorio Sánchez, Ernesto Lagos, and Luis María de la Torre. A landmark of modernist architecture, it was inaugurated in 1936 as the tallest building in Latin America, surpassing Montevideo’s Palacio Salvo (1928). Additionally, it held the distinction of being the tallest reinforced concrete structure in the world at the time.

The Kavanagh Building Design Intent & Spatial Qualities
At first glance, the Kavanagh Building is composed of stacked, receding volumes, reminiscent of early Art Deco skyscrapers yet stripped of superfluous ornamentation. Its tiered silhouette, dictated by local zoning laws, results in a carefully sculpted massing strategy that mitigates its imposing scale while creating dynamic light and shadow play.
Unlike the classical tripartite organization of many early skyscrapers (base, shaft, crown), the Kavanagh disrupts conventions by employing a fluid yet rigorously composed verticality. The absence of a traditional ornamental crown, typical of Art Deco, signals a departure towards functionalist modernism, where form follows programmatic and structural logic.
The organization of the interior reflects this modernist ethos, with apartments designed to maximize natural light, ventilation, and efficiency. The building features only one entrance, reinforcing its exclusivity while maintaining an urban presence. Internally, circulation spaces are compact yet functional, with a centralized service core allowing flexible residential layouts.
Set against the backdrop of Plaza San Martín, the building establishes a dialogue with its surroundings. Its facade modulation and setbacks create a rhythm that prevents it from becoming an overpowering monolith despite its dominance in the skyline. The asymmetrical volumetric composition further reflects an urban sensitivity that modernist high-rises often neglect.
The Kavanagh’s engagement with the city is assertive and nuanced—a landmark that simultaneously integrates and disrupts. The placement of balconies and windows creates a calculated sense of permeability, allowing the private realm to subtly interact with the urban fabric.
Materiality, Structure & Construction Innovations
The Kavanagh Building pioneered the use of reinforced concrete, a material that enabled its height and structural ingenuity. At a time when steel-frame construction dominated high-rise design, the decision to use concrete was both pragmatic and forward-thinking, enabling slender structural supports and an efficient floor plan.
Concrete, as a material of modernity, offered a monolithic quality that aligned with the project’s functionalist aspirations. The structural system allowed for large spans and open-plan living, with minimal reliance on interior load-bearing walls—anticipating the flexible layouts that would become standard in modern high-rise design.
From an engineering perspective, the use of concrete in such a tall building was unprecedented. Advances in construction technology made it possible to create a vertically stacked structure without excessive weight, a critical challenge in early skyscraper design.
The building’s façade is defined by its rigorous simplicity. Unlike the highly decorative Art Deco skyscrapers of New York, the Kavanagh pares down embellishment to a refined interplay of mass, void, and materiality. Its surface is largely unadorned, relying instead on carefully proportioned windows and setbacks to create depth and articulation.
Despite this minimalist approach, subtle details—such as wrought iron balcony railings, stone cladding at the base, and custom metalwork on doors and windows—hint at a high level of craftsmanship, demonstrating that modernism need not reject refinement.
Urban & Cultural Significance
Few buildings in Buenos Aires have had the cultural and symbolic impact of the Kavanagh. It was, and remains, an unapologetic statement of modernity, challenging the classical European architectural traditions that had long shaped the city.
Plaza San Martín is a theatrical foreground to the building’s presence, emphasizing its sculptural silhouette. Its placement allows for uninterrupted views, making it a visual and experiential landmark.
This urban positioning underscores its exclusivity—the Kavanagh was not merely a residential building but an elite statement embodying the aspirations of modern Argentina.
Controversy & Social Implications
Despite its architectural triumphs, the Kavanagh’s legacy is not without controversy. Designed as an exclusive residential tower for Buenos Aires’ elite, its single-entry circulation and isolated living units reinforce a social hierarchy that modernist urbanism often critiqued.
This exclusivity raises broader questions about who modernism serves. Was the Kavanagh an experiment in functionalist efficiency, or was it simply a rebranding of luxury under the guise of modernism? This tension between innovation and exclusivity remains relevant in contemporary architectural discourse.
The Kavanagh Building paved the way for modernist residential high-rises across Latin America, influencing generations of architects. Its bold massing, restrained materiality, and structural innovations foreshadowed many of the principles that would define post-war modernism.
Today, as Buenos Aires continues to evolve, preserving the Kavanagh presents technical and philosophical challenges. How do we maintain a modernist landmark without compromising its original intent? What does the building teach us about the endurance of modernist principles in contemporary high-rise design?

About Sanchez, Lagos y de la Torre
Sánchez, Lagos y de la Torre was one of Argentina’s most influential architecture studios in the first half of the 20th century. It stood out within the rationalist and modernism trends of the time.
It was formed in the 1920s by the engineer Gregorio Sánchez and the architects Ernesto Lagos and Luis María de la Torre Campos. Although his first works conformed to the academic aesthetic that had been in full swing in Buenos Aires since the end of the 19th century, they quickly advanced towards new currents such as art deco, leading to the ornamental sobriety of rationalism.
