The seriously rich wrestle with issues that most of us never have to consider. Problems such as: shall I customise my Learjet so that I can stand upright in it? How can I make it to number one on the rich list? Do I own too many Basquiats and Koonses? Should I go public on my $2bn Gates Foundation donation?

While many deliberate over these conundrums, one overriding issue surpasses all the others: where should I stash my cash and, therefore, where should I live?

Sir Richard Branson enjoys the more adventurous options of kitesurfing and surfing which is why he has opted to swap life in Oxfordshire for life in the Caribbean on his very own Necker Island, part of the British Virgin Islands.
