Casablanca and its constructions, its age-old history, small-scale African New York, … filled with surprises and hidden facets, savage and frail. Casablanca the Beauty, at times turning beastly.

From this nomadic observation are born exchanges, forms, sketches like so many geo-expressive maps that intertwine interstitial zones, no man’s lands and saturated landscapes.
