World's most expensive houses - topped by British £1 billion home

The British property named as the most expensive in the world - and the rest of the top ten

Updated: 
UK, London, Buckingham Palace

A study of the most expensive homes in the world has revealed that Buckingham Palace is the priciest of them all. The 775 room palace was valued at an incredible £1 billion - which is perhaps unsurprising for a home which features 52 royal bedrooms and 188 staff bedrooms, and comes with its own enormous gardens in the midst of prime central London. It means the Queen pushes the world's billionaires and oligarchs (who aren't used to second place) further down the list.

The study was done by American website comparecamp.com, and the rest of the top 10 was:
