One Cornwall Terrace is a Grade 1 listed mansion overlooking Regent's Park in London.
The breathtaking property is spread across 21,500 sq/ft and boasts seven bedrooms, nine bathrooms and 11 reception rooms, the Daily Mail reported.
It is being marketed by Savills with an asking price of 100 million pounds, 4,651 pounds per sq/ft, making it one of the most expensive houses ever put up for sale in England.
At this mega price, the buyer would have to pay 7 million pounds in stamp duty alone.
But they would also pay just 1,369 pounds-a-year in council tax, the same as a 320,000 pounds property with Westminster Council, the second cheapest borough in London.
Cornwall Terrace was originally designed and built in the 1820s by renowned architect Decimus Burton with the project overseen by the acclaimed John Nash.
