Aiming at the creation of an Ayyappa Temple at Bhosari, in the industrial city of Pimpri Chinchwad Pune, Shree Ayyappa Sevashram Charitable Foundation was established in January 1994. SASC Foundation stands not only for the religious function, but also have extensive welfare and cultural activities. Free periodical medical aids, free food to poor, basic spiritual education to children, are few. The objective of the Trust is not merely to create a temple, but is always to render a helping hand to the poor. Construction and establishment of a new temple for the worship of God is a divine scintillation of rare spiritual experience. As a result of great perseverance of Bhosari devotees, the existing place of Bhosari temple, on a 12000 sq.ft. plot on Pune Nasik Highway, was acquired in 1998.

Followed by the Ashtamangala Devaprasna by Dr. Mannar Krishna Pillai, on 18.06.1997, the construction of the temple was done by the renowned Temple Architect Shri Kanipayyoor Kuttan Namboothiri. The temple complex consists of three floors, of 5000 sq.ft. each – an Annadanam Hall, Community Hall, and chancels on the top floor.
