Laprade worked under Prost in the town planning division, and was given the tasks of redesigning the great central park in Casablanca, and then planning a new indigenous town.[3] Laprade first made many drawings of local architectural motifs in an effort to understand the interaction of stylistic elements with social functions. His goal was to develop an elegant urban architecture based on modern technology that would be appropriate to the stylistic tastes and way of life of the Moroccan people.[4] His new Madina in Casablanca was separate from the French quarters and very different in design. Laprade followed Moroccan traditions in the division between interior courtyards and the street.[5] His new quarter, in neo-Moorish style using modern materials, technology and sanitary principles, included pedestrian walkways, courtyard houses, markets, communal ovens, mosques, schools and public baths.[6]
