As with other Alaouite structures of the 18th-19th centuries, the decoration of the pavilion is relatively austere compared to earlier periods of Moroccan architecture. On the exterior, the corners and edges of the pavilion's walls are painted to look like brickwork, while geometric and epigraphic decoration are painted around the southern entrance doorway and around some of the windows. The door to the northern balcony overlooking the water is framed on the outside by a large, prominent, semi-circular blind arch highlighted with a keystone motif.
