This square structure with each of its four sides being identical, was in a poor state of preservation with much of the western façade in a state of collapse and the southern facade reconstructed by the ASI in 2002-4 to an inappropriate design thus requiring to be demolished prior to an accurate reconstruction. The northern façade was the best preserved. During conservation works the inappropriate reconstruction carried out in previous conservation attempts by the ASI was carefully dismantled followed by reconstructing the half-domed profile on each of the five bays on the southern façade and two bays of the eastern facade.

The kangura patterns on the parapet were reconstructed by replicating from the existing patterns and finished in red polychromy and turquoise tiles. The inappropriate past repairs carried out on the terrace like undulating multiple layers of cement concrete were manually removed and replaced with lime concrete comprising lime mortar and brick aggregate. The rainwater spouts were missing, leading to rainwater percolating into the masonry and causing deterioration of the wall plaster. Red sandstone water spouts have now been hand chiselled and four have been fixed on each of the four façade. After a careful documentation of the existing remains of original incised plaster work, restoration work of the decayed decorative patterns was undertaken. Completion of the restoring the decorative plasterwork included decorative lime plastering along with lime punning. The restoration of the incised plasterworks was carried by the master-craftsmen.
