The timber hammerbeam roof features tie beam trusses with panelled tracery spandrels. The spandrels have yalis and decorated roundels. Bending members are also known as beams, girders, joists, spandrels, purlins, lintels, and girts. The engrailed spandrels and bases are inlaid with precious stones. The facade consists of five arches, each with lotus medallions in the spandrels. Their names are written on the spandrels of the arches with gilt letters. This was particularly the case for the lunettes, spandrels and lower parts of the pendentives. Between each floor are terracotta spandrels, which are recessed behind the piers. The spandrels over doorways in perpendicular work are generally richly decorated. Winged Victories are carved in relief in the spandrels. The spandrels on the upper floor have allegorical female figures with wings. The design is used in the "mihrab's" spandrels. The bridges all employed diamond-shaped bracing in the arch spandrels. The four tondi of the spandrels depict allegoric representations of the "Seasons". The upper stories of the building rest on a recessed base with royal blue spandrels.
