The building complex also includes the large Asfi mosque, the Bhul-bhulaiya (the labyrinth), and Bowli, a steep well with running water.

[1] The architecture of the complex reflects the maturation of ornamented Mughal design, namely the Badshahi Mosque; it is one of the last major projects not incorporating any European elements or the use of iron.

The main imambara consists of a large vaulted central chamber containing the tomb of Asaf-ud-Daula.

There are eight surrounding chambers built to different roof heights, permitting the space above these to be reconstructed as a three-dimensional labyrinth with passages interconnecting with each other through 489 identical doorways.

The winner was a Delhi architect Kifayatullah,[1] who also lies buried in the main hall of the Imambara.
