This industrial complex operates as a facility for sorting, grading, and packing citrus fruits, primarily oranges, for the domestic market. Its main structure is defined by a roof of tensioned double-curved vaults.

Architecturally, the building stands out for its remarkable 45-meter clear span between columns, achieved through a reinforced concrete structure supported on drilled pile foundations.

The roof is the building’s most distinctive feature: a system of 17 tensioned double-curved vaults built in reinforced ceramic using hollow clay units. To improve thermal comfort under Uruguay’s northern sun, the roof was coated with a layer of white-painted mortar specifically designed to reflect solar radiation.

This 4,200 m² complex serves as the operational core of a thriving agro-industrial enterprise. Its construction not only enabled the processing and packing of citrus fruits, especially oranges, for direct export from the port of Montevideo, but also structured the overall layout of the site.

The project unified the company’s various activities both visually and functionally, from machinery maintenance to transport-fleet logistics.

The envelope is completed with hollow brick walls, while natural lighting is ingeniously achieved through transverse openings in each vault. These glazed skylights, framed with metal supports, fill the interior with overhead light, ensuring an efficient workspace aligned with Dieste’s philosophy of using materials in a rational yet expressive way.
