MEMORY
Achával 584 is a residential complex located in Parque Chacabuco, a neighborhood historically shaped by mid-20th-century collective housing developments that addressed the needs of the working class. In recent years, the increase in population density in Buenos Aires and the implementation of the new Urban Planning Code have reactivated the area as a strategic site for new residential projects.
The building is set on an atypical plot that wraps around an existing corner structure and encompasses three parcels per side. This condition raises a central question: how to introduce a building of considerable scale within a traditionally low-rise neighborhood characterized by houses with inner patios and tree-lined streets, without negatively impacting its urban character.
The architectural response is based on a series of design strategies that mitigate the perception of height through strong horizontal articulation. Continuous window systems, sunshades, and exposed concrete beams run along the perimeter of the building, counterbalancing its verticality and establishing a clear relationship with the surrounding context.
The exposed beams play a dual role. At an urban scale, they allow the new volume to establish a morphological dialogue with the existing corner building, integrating it into a continuous system. At a domestic scale, they organize the exterior modules of the dwellings, incorporating planters in front of private spaces and seating areas facing more public zones, all resolved through a single concrete element.
The sunshade system introduces flexibility to the façade, allowing different degrees of openness—fully closed, partially open, or fully open—responding to privacy and environmental needs, particularly on the lower levels. This results in a dynamic façade that changes over time and use.
Finally, the project emphasizes the incorporation of greenery as a response to the neighborhood’s strong landscape identity and its proximity to Parque Chacabuco, one of the largest green spaces in the city. Vegetation is integrated into private expansions, internal courtyards, and the rooftop, conceived as a contemporary interpretation of the “fifth façade” that combines public and private outdoor spaces.
