This massive home is located at 18 Carlton House Terrace in London, England. It is said to be owned by a Saudi royal who will not allow updated pictures to be taken of the home. The 6-story Grade I listed Regency mansion features approximately 50,000 square feet of living space. The last two pics were taken in the 1890’s and shows a grand y-shaped double staircase. It is secretly on the market for a whopping £250,000,000 or $381,275,000. So not only is it one of the largest private residences in London, but it will also be the most expensive if it ever sold for that much money.
