The Undeshwar Temple is supported by a tall vedibandha (basal mouldings), intricately carved and featuring multiple moldings. The jangha (wall) of the garbhagriha (sanctum sanctorum) has bhadra (central offset) on each of its three sides. The space between these bhadras is occupied by projected stambhas (buttresses). Carved with depictions of deities, these bhadras enhance the temple's aesthetic. The shikhara (superstructure) of the garbhagriha follows the Bhumija architectural style.
The jangha (wall) surrounding the garbhagriha (sanctum sanctorum) of the Undeshwar Temple is extensively adorned with sculptures. The bhadras (central offsets) display divine figures, while the stambhas (buttresses) are carved with representations of ashta dikapalas (deities representing eight cardinal directions), surasundaris and apsaras (celestial damsels), musicians and dancers.
The exterior of the southern garbhagriha (sanctum sanctorum) of the Mahakal Temple has a vedibandha (basal mouldings), jangha (wall) and shikhara (superstructure). The vedibandha mouldings are adorned and the jangha showcases bhadraratha (central vertical projection), intricately carved stambhas (buttresses) and jali (lattice) work. The shikhara of the temple is built in Shekhari style i.e., the central latina spires with rows of half spires added on either side.
The temple complex features a tranquil reservoir, known as the Mandakini kund (water tank), positioned behind the Mahakal Temple and in the left front of the Undeshwar Temple. Alongside the three temples within the complex, the Mandakini Kund is safeguarded as a protected monument under the jurisdiction of the Jaipur Circle of the Archaeological Survey of India (ASI). Serving as a sacred water body within the Bijolia temple compound, the Mandakini Kund is a site where devotees frequently engage in ceremonial bathing rituals.
Access to the temple is granted through the mukhamandapa (front porch) of the Undeshwar Temple, with steps bordered by depictions of deities. The mukhamandapa is a small hall with low walls along its sides. Atop these walls, four pillars stand at each corner, offering support for the flat roof above.
The mukhamandapa (front porch) serves as an entryway to the mandapa-pillared hall) of the Undeshwar Temple, which features lateral extensions. In the mandapa, tall pillars with square bases support an octagonal shaft that transitions into faceted and circular sections. The square bases of the pillars are adorned with carvings depicting various deities, including dikapalas (deities of cardinal directions), surasundaris (celestial damsels), female dancers, and musicians. There is a square shallow platform at the center on which a Nandi is placed.
A closer view of the jangha (wall) of the Undeshwar Temple exhibits carved stambhas (buttresses) positioned between the bhadras (central offsets). Each side features five buttresses, with the central one depicting the dikapalas (deities of cardinal directions), while the others portray female dancers, musicians, surasundaris (celestial damsels), and alasa kanya (a form of indolent female or maiden).
The depicted image is of the jangha (wall), and garbhagriha (sanctum sanctorum) of the Undeshwar Temple features a dancer and a cymbal player, both shown from the rear with their upper bodies twisted towards the viewer. One of their arms is raised while the other is lowered. The dancer is making classical dance gestures, while the cymbal player holds cymbals in both hands. They possess voluptuous figures, and their beauty is accentuated by their ornate jewelry.
Ishana is portrayed, on the kakshasana (seat back) of the Undeshwar Temple, with four arms, carrying a trishula (trident) and a sarpa (snake) in his upper hands. In his lower hands, he holds a kamandalu (water pot) and extends a varadaksha (giving blessing) gesture. Adorned with a jatamukuta (crown of matted hair) and jewelry, his vehicle, the bull, is depicted at the bottom right.
A notable characteristic of this temple is the intricate carving of makara toranas (ornamental gateways/arches crafted with mythical crocodile creatures flanking on both ends) crowning the central four pillars of the mandapa (pillared hall) of the Undeshwar Temple. These toranas significantly enhance the beauty of the mandapa.
