The Nissanka Latha Mandapaya, constructed by Nissanka Malla is a unique type of building.
It contains 8 granite pillars which were used to support a roof.
The pillars are carved out of granite in the form of lotus stems with opening lotus buds on the tops, and are positioned on a platform.

The Hatadage is another construction done by Nissanka Malla.
This building was constructed to keep the Relic of the tooth of the Buddha.
The Rankot Vihara, the fourth largest stupa in Sri Lanka, was also constructed by Nissanka Malla.

A major refurbishment was carried out at the Dambulla cave temple by Nissanka Malla.
A rock inscription records that he has spent 7 lakhs for this.
However, another of his own rock inscriptions contradict this statement and mentions the sum as 1 lakh.
The interior of the temple was gilded during the refurbishment.
This later earned the temple the name Ran Giri, meaning golden rock.
Nissanka Malla also had 50 Buddha statues in the temple gilded, and had this recorded in a rock inscription near the entrance of the temple.
A statue of Nissanka Malla was also made in one of the caves.
