The idol of Sudarsanamoorthy features four arms, each carrying a different object: a conch shell, a chakra (discus), a gadha (mace) and a lotus bloom.

The foreground of the temple is spacious and paved with rough-hewn granite slabs. The Namaskaramandapam is also fittingly large and impressive. On the ceiling of this Mandapam are exquisitely carved figures of Ashtadikpalakas (guardians of the eight directions) with Lord Brahma in the middle.

A characteristic feature of Kerala temple architecture is that many Sreekovils contain more than one chamber. The large, circular Sreekovil contains three enclosures. Two circumambulatory paths go around the Garbhagriha. On one of them are some tall, granite pillars. A casual observer may not see the Dwarapalas (entrace guards) at first. They are installed within the veranda adjoining the Sreekovil.

The outer walls of the Sreekovil are profusely adorned with intricately sculpted woodwork. One of the very interesting sculptures is that of Devi breastfeeding Ganapathy. Depictions of this nature are very rare. Sculptures of Devi astride the Nandi with a bell in her hand, Ganapathy depicted in different rows and a frozen dance-and-music extravaganza are some of the visual treats here. On either side of a narrow doorway (which looks like a window), one can see miniature figures of an entourage of servant-gods.

The gold-plated flagmast on the eastern side of the Sudarsanamoorthy temple is taller than its counterpart for the Narasima temple.

For the rituals and pooja offerings, the well and the kitchen in the Sudarsanamoorthy premises are shared by the two temples.
