The world's most expensive houses, on Sotheby's listings anyway, are a diverse group of properties. They range from state-of-the-art villas in the bustling but beautiful South of France to vast, isolated wineries in the USA. And while not every aspect of each of them is to everyone's tastes, each is extraordinarily beautiful in its own way and each has two things in common with the others: plenty of outside space and views to die for – both vitally important to all of us during the ongoing pandemic.

We spend much of our time seeking out the world's best homes, and while 'expensive' doesn't always necessarily equate to 'best', we can say with some confidence that the locations, amenities and gardens of these homes are some of the most stunning we have ever seen. Enjoy.
