The “mega-mansion”, which will be sold to a single owner, will claim the title of London’s biggest residence after Buckingham Palace – an accolade currently held by Witanhurst House in Highgate. If sold for more than $200 million, the Regent’s Park development would also claim the title of London’s most expensive home.

A 40-ft roof garden, complete with a sliding ceiling and overlooking Regent’s Park, will be built into the eaves, and the development will come with two additional staff houses.
