The pent roof covering the storey below and the apsidal ridged roof above, with a gable front,
has a row of three Stupis on top.
All the five Stupis are of metal and they together form a pancha kalasa scheme,
that according to ancient Buddhist texts should be the character of a divya vimana.
They are essentially oblong on plan, transversely linear, with the entrance running through at the middle, and, with a single simple or storeyed superstructure,
terminated by a sala sikhara with a row of Stupis.
The oblong and
ellipsoidal body structures with a wagon- top, vault- like or inverted boat- like roof, or sikhara with a row of Stupis on top along the ridge,
are known as sala vimana, or koshtha, or sabha forms.
The top storey over the innermost wall is covered over by a conical or four- sided kuta roof with a single finial in the case of circular, octagonal, and square structures, or by a ridged sala or sabha
type on gable walls, with a row of Stupis in the case of the oblong and apsidal structures.
