World's largest home

Mukesh Ambani is the 5th richest man in world. He is head of Reliance,  petrochemical industries, and just build a 27-story home in Mumbai. From my grandma's balcony one can view his home.  At night it is lit up with different colored lights. Since it's only a few blocks from my grandma's flat we decided to check it out one evening. Upon arriving at his home guards were stationed within the 18 foot gates. The first 6 floors is a garage, there are 3 hellipads, a swimming pool and a theater. There were other people who were also curious at the grandeur of his home and we were all trying to take photos, but the guards would not allow it.
