[7] At the beginning of the 20th century, the upward social mobility was quite more dynamic in Mar del Plata than in Buenos Aires itself, paving the road for a strong middle class, based on tourist services, the building industry and a prosperous commerce.
[13] Nonetheless, the first generation of architects and architectural engineers from Mar del Plata, led by young professionals like Auro Tiribelli, Alberto Córsico Piccolini, José V. Coll, Gabriel Barroso or Raúl Camusso played a key role in the consolidation of the style during the late 1930s an early 1940s.
[25] The neighborhoods of La Perla, Stella Maris, Playa Grande, Punta Mogotes and Alfar have today the main concentrations of Mar del Plata style houses.
[26] These seaside areas attracted many middle-class tourists, particularly La Perla, thus the chalet played the dual role of home in winter and house for rent in the summer season.
[28] The oldest residences built in Sierra de los Padres, a hilly area 12 miles west of the city, are also Mar del Plata style chalets.
[30][31] There is a municipal agency which provides tax benefits for the owners to secure the maintenance or restoration of the houses and a handbook with preservation guidelines, created by architect Lorena Marina Sánchez.
