18-19 Kensington Palace Gardens

Situated on London's priciest street (the 2nd most expensive street in the world) is one of two of Lakshmi Mittal's mansions on that street.

It features an indoor pool, has 20 parking spots (a big deal in such a tightly packed city), and a Turkish bath. After it's remodeling, it's unclear how many bathrooms there are or how much acreage is left on the plot, but who cares. I'm sure it's more than most.

6. Billionaire at Bel Air ($150 million)
