Terraza Palace, Rationalist apartment building in Mar del Plata, Argentina.

Terraza Palace is a rationalist apartment building in Mar del Plata with eight floors and integrated balconies and windows arranged perpendicular to its main facade. It contains forty housing units with natural lighting through staggered balconies and double-height courtyards that improve air circulation throughout.

Antonio Bonet Castellana, a rationalist architect of the Austral Group, designed the Terraza Palace in 1957 for paper industrialist Norberto Blumencwejg; construction by Dante Bernasconi finished a year later, and the first stage was inaugurated on 2 January 1960, with work continuing in phases. It rose alone among the chalets of Playa Grande, part of the late-1950s rebuilding of Mar del Plata as a mass seaside resort.

The building shows mid-20th century living culture through its functional design and shared spaces built into the structure. This layout reflects how residents lived and used their homes during that era.

The seaside location with ocean views makes this a notable landmark visible from various points across the city. Keep in mind that this is a private residential building and can only be viewed from outside.

The two BFK lounge chairs in the lobby were designed in 1939 by Antonio Bonet Castellana with Jorge Ferrari-Hardoy and Juan Kurchan, during the Casa de Estudios para Artistas project in Buenos Aires. Neighbours spread a rumour that the building belonged to the Olivetti typewriter company. A plaque at the entrance recalls the 1999 municipal awards for heritage preservation and original modern architecture.
