An Indian owns the largest house in the world which is valued at more than a billion dollars! These houses or rather mansions are soaked in luxury with gold embellishments, marbles, crystals, helipads, acres of gardens, garages with the fanciest cars and rooms that run in 50s and 100s - stuff that dreams are made of. Some of the houses have hosted presidents and movie stars and also featured in movies and TV series. And then there are a couple of palaces hearing about them would leave you spellbound and speechless!
