Jinnah House in Mumbai was the Mumbai residence of founder of Pakistan - Mohammad Ali Jinnah. The house stands on a 2.5 acre property in Malabar Hills area on Bhausaheb Hirey Marg (Mount Pleasant Road) right in front of the official residence of Chief Minister of Maharashtra.
Jinnah had purchased this house in 1917 and had it rebuilt by architect Claude Batley with Italian marble and walnut wood in 1936 at the cost Rs. 200,000. This was the place where at the age of 41 Jinnah fell in love with young Parsi girl Ruttenbai and married her after she turned 18.
This house was the place where discussion regarding partition of India were help. Exactly an year before India gained independence, Jinnah and Nehru met at this house to hold talks that altered the course of Indian history.
Here's a photograph of Jinnah announcing formation of Pakistan from his residence.
Jinnah was extremely attached to this house and had requested Nehru to allot the house to any foreign consulate. British deputy high commissioner occupied this house from 1948 to 1982. Part of this house is now occupied by Indian Council for Cultural Relations.
Jinnah's descendants in India, the Wadia family (Bombay Dyeing) have staked a claim on this property. It is currently worth about US $15 million.
