The complex has its own garden, planned so the temples have what they need for daily worship. It grows Tulsi, Athi, Ithi, Arayal, Peraal, Ashokam, Champakam, Parijatham and Elanji, so the flowers and leaves for the poojas come from the temple grounds. This follows the old Kerala custom of a sacred grove (Tapovana) beside the temple.
The Devaki Krishna temple has the tallest tower in the complex, at 16 metres. The Maha Ganapati temple tower is next, at 14 metres. Every temple has a cellar below it and a path around it for Pradakshina (walking around the shrine). The idols are carved from black granite (Krishna Shila), and the floors are marble.
At the entrances stand the Dwara Palakas, the doorkeepers described in the scriptures: Gopakumara, Pushti, Thrishti, Nandi, Shringi and Jaya-Vijaya. There is also a separate shrine for the Navagrahas, the nine planets.
GSB families have looked after the Vedas, Upanishads, Puranas and the practice of Karmashuddhi for generations, and that care for tradition is part of how the complex was built.
