In 1917 Laprade went to Rabat where he assisted with the General Residence and its gardens, the military and diplomatic cabinet, a park and sports ground, and the Marshal's residence. In this last he incorporated concepts from local architecture, ensuring harmony with the surrounding buildings.[3] Auguste Cadet and Edmond Brion undertook the madina construction project in Casablanca, which started in 1919 and continued for many years.[7] Laprade met many of his future private clients while in Morocco.[1] His sketches of local gardens and houses were later used to illustrate Jean Galotti's Les Jardins et les maisons arabes au Maroc (1926).[8]
