The 'American Idol' judge is delighted with all the renovations and improvements that have been carried out on his 12,000 sq ft mansion - dubbed 'Chateau Cowell'.
Simon told his 'Britain's Got Talent' co-judge Piers Morgan: "Nice, isn't it? I'm so happy. It's the first time I've felt properly happy since I came to Los Angeles."
The home, located in the exclusive Beverly Hills area of the city, has its own private cinema with black leather seats, and a poolside sound system which cost £20,000.
The pool itself is adorned with blazing "turrets of fire" which light up at the sides and palm trees.
Simon - who turns 50 next month - has also recruited several servants to look after the property and serve guests.
