Alejandro Bustillo (18 March 1889 – 3 November 1982) was an Argentine painter and architect who designed numerous buildings including iconic landmarks in Buenos Aires, Mar del Plata, and Bariloche.
From 1924 until 1937 he consolidated his career with a large number of works including commercial buildings, private houses and rental property.
The building, made almost entirely of wood, was destroyed by fire soon after its completion in 1939 and a year later Bustillo built a new hotel out of reinforced concrete and stone.
Bustillo also designed numerous landmark works in Mar del Plata during the 1940s, including the Grand Provincial Hotel, the Casino, the seaside esplanade joining each, and City Hall.
Among Bustillo's best known later works was the National Flag Memorial in Rosario, designed in 1944 with fellow architect Ángel Guido and completed in 1957.
