If your current four walls are starting to feel a little uninspired, perhaps it's time to upgrade... to an entire island! Why settle for a garden view when you could have 360-degree ocean vistas, your own stretch of sandy beach, and zero risk of noisy neighbours (unless you count the seagulls)?

From tropical hideaways to sprawling ocean retreats, these private islands offer the ultimate escape – if, of course, you happen to have a few million to spare.
