It's NOT a $ 2 billion house....guys remember, its a $2 billion house...
once it is open we can expect some mass mails from friends / relatives about the picture scoops of the interiors as it usually happens with all the high profile buildings around the world.Unless he builds walls as tall as his building he will be seen from outside very easily.
thats what you get when u build a tall dabba for yourself. while on third floor or fourth floor , all they will see is a wall in front of them.
though he has all the rights of keeping the secrecy i hope release pics of interiors at some point of time.
