The billionaire entrepreneur, recently ranked the world's 212th richest man, gave the Oprah Winfrey Show unprecedented access to Necker, his 74-acre Caribbean island.
He gave presenter Nate Berkus a tour of his home, which he has recently finished building, his cliff top guest house and his extravagant toys.

Asked about the purchase of the British Virgin Islands property, for a mere $200,000 in the late 1970s, he referred to his pursuit of wife Joan.
He said: 'I was about 26-years-old, I was chasing this beautiful lady, trying to persuade her to come live with me and we discovered this beautiful islands.
'I somehow managed to get the island, get the lady and get the mother of my children.'

He added: 'I appreciate every moment of my life. I was born under a lucky star.'

Branson started off the tour with the main home, boasting a stunning moon-shaped infinity pool next to a luxurious bar, a master bedroom with virtually no walls, an open kitchen and an outdoor bathroom - all with amazing views of the turquoise waters of the Caribbean.
Asked if the design reflects his personality, he replied: 'I hope so. I would like to think I'm quite an open person and this is open.'
The 59-year-old ended the home tour with his office - where he does business from his white hammock.

On his throne: Branson joked around with his guest
Next stop was his cliff top guesthouse, boasting another outdoor bathroom all in stone.
And Branson showed his sense of humour - and ego - as he sat down on the toilet.
'This is my throne and, being a knight of the realm...' he said, before whipping out a crown and putting it on his head with a big smile.
Then it was time for the jewel in his crown - the Necker Nymph, an aero submarine with an open cockpit owned by nobody else in the world.

Branson announced the purchase earlier this year and the toy will be lent out to guests of his island, which is available for rent as part of his Virgin Limited Edition luxury line.
The submarine uses its wings to create downward lift underwater and is fitted with scuba gear for its pilot and two passengers.
'It's like an airplane that flies underwater, a little fighter plane,' Branson said.
And he allowed cameras to shoot as he went for his first ride on the Nymph, describing the experience as 'brilliant' through microphones fitted on his scuba gear.

Branson then showed off the Necker Belle, his $30m luxury catamaran, featuring a lift on the main mast that gives panoramic 360 degrees views of the sea.
There he was joined by his children Holly and Sam.
Sam said the best advice he ever gave him was 'probably to be yourself... he never put pressure to conform in any sort of form.'
At the end of the show, Branson signed up to Oprah's No Phone Zone drive to outlaw talking on mobiles and texting while driving in the US.
