Architecture of Chennakesava temple
Chennakesava temple is made of soapstone. The plan is fundamentally a simple Hoysala plan that has been built with amazing detail. The basic part of the temple is unusually large in size. The temple is a single shrine design. A large entrance hall connects the shrine to the hall. There are 60 bays of the mandapa. The tower on top of the vimana has dilapidated over time. The temple is built on a platform. There is one getaway of steps that leads to the platform and another set of steps that leads of the mandapa. The platform helps the devotee to do a pradakshina around the temple before entering it. The jagati is constructed in a staggered square design and the shrine is star shaped. Initially it was an open mandapa, however later it was transformed into a closed one that was done by erecting walls with pierced window screens. There are 28 such windows which have star-shaped perforations and bands of foliage, figures and mythological subjects. On one of the screens King Vishnuvardhana and his queen Shanatala Devi are depicted. Another screen depicts the king in a standing posture.

The shrine is at the back of the mandapa. Each side of the vimana has five vertical sections that comprise a large double storied niche in the centre and two heavy pillars on either side. These are rotated about their vertical axis in order to produce a star-shaped plan for the shrine. These bear many ornate sculptures that re of earlier style. Vimana's shape indicates that the tower above it would have been of the Bhumija style. The Bhumija towers are a type of nagara tower which are curvilinear in shape. This shape is uncommon in pure Dravidian architecture.
