This is dubbed the "millionaires' playground" by Private Islands Online due to its clear ownership by a private company that has approval to build 6 villas and permission to subdivide into 6 plots. The region is also touted as having idyllic conditions for water sports, sailing, fishing, deep sea diving and swimming.
The Bonus is it costs less than than buying a house in some upmarket parts of London.
