From the residence, the south wall of the qasba, later partly obliterated by the new bastioned trace, ran west and then, just behind the new south-west half-bastion's orillion, tracked slightly north.
Inclusive of the garden, the residence filled the space between today's Bab Haha and Bab el-'Assa gates, while its south wing extended into the throat of the Portuguese south-east bastion, between the orillions. Much later on, part of this building lot was allocated to the stables facing, across the Sahat al-Kasba, the Dar al-Makhzen's Treasury annex (Bait alMal) (configuration documented in 1904-10).
The draught either "proposes" or depicts the encapsulation of this baluarte within a simple "angle bastion" shell with miniature orillions. The lack of elevation drawings makes it difficult to visualize the structure.
