The original 1,842 m2 bank was designed in 1922 by Auguste-Alexandre Cadet and Edmond Brion. The carved stone of the facade is the work of stonemasons Ahmed Benthami (Moroccan, 1931-2011) and Si Mohammed Cherkaoui (Moroccan, Active 20th Century). In 1924 a second 3,582 m2 parcel behind the original was purchased, and the extension completed in 1930. The extension architect was Mourad Ben Embarek. The interior features intricately carved stucco and wood.
