The original lime plaster of the dome had suffered significant damage. The 20th century cement covering the dome was removed revealing deep holes, possibly left during past repairs to support the scaffolding and later superficially filled without adequate protection against water ingress into the dome’s masonry.

During the conservation of the mausoleum, these were filled with stone masonry in lime mortar.Over two dozen skilled craftspeople worked simultaneously to re-plaster the dome in order to minimize the joints in the successive layers of lime plaster.

Archival photographs dating back to 1860s provided crucial evidence for the restoration of the parapet. They showed a solitary parapet stone surviving on the western edge of the upper plinth. Taking cue from the archival evidence and replicating the historical design found on similar monuments at the necropolis, a total of 144 granite blocks, each weighing a staggering 2000 kilograms were hand carved and reinstated.

On inspection, it was found that the principal tomb chamber originally had openings on all four sides, with the ones on the north and the south closed at a later date. The external facade of the doorways was marked with ornate bands on all sides. Except for the east side, these bands were tampered and covered with modern layers in cement. The bands on the south and the north side are now restored. However, the openings were not reopened. 

Inside the cenotaph chamber, scaffolding equivalent to a five-storey building was erected to access the domed ceiling. Here, layers of modern paint and cement were removed from the central floral medallion, and it was repaired using traditional lime mortar and natural colors. Arch moldings, bands, arch crowns were also restored with lime mortar.

The tomb's unique feature – an accessible crypt chamber – was also found in need of repairs.  Documentation revealed the monument was enlarged with a peripheral bay at a later date than the original construction. It was also discovered that earth levels in the crypt were insensitively altered. Trial trenches were made to find the original levels of the crypt. This also revealed a hidden trove of coloured glazed tiles. This discovery, along with historical records, confirmed the use of such tiles on the monument's facade. Sadly, these tiles are now lost, but the knowledge gleaned from the crypt allows us to have a better understanding of this tomb’s original appearance. Intrusive brick screens at the elevation of the crypt from the 1980s were replaced with simple recessed metal for light and ventilation. 20th century cement concrete was also removed from the roof, thereby reducing the weight on the monument Hand-chiselled granite steps and a ramp for universal access were installed. To ensure rainwater disposal, 45 metal water-spouts were installed at the upper plinth level.  To ensure rainwater disposal, 45 metal water-spouts were installed, and the plinth was paved with stone to limit water ingress.
