Instagram The couple are selling their home “off-market” and posted a 10-minute video to Instagram in order to entice potential buyers .
Ms Ecclestone explains that the makeover of Sloane House took her five years to complete and she “absolutely adores it”.
The video shows the impressive exterior of the Grade II Georgian home before panning to Ms Ecclestone and Mr Palmer who introduce their eight-bedroom, 12-bathroom property.
The video follows the couple inside into the foyer which features a giant gold drinks bar and a custom-made chandelier.
Ms Ecclestone shows off a soft play area for children, which is the size of a two-storey house, and a cinema complete with its own pick and mix station.
There is also a large dining room, a huge walk in wardrobe, a kitchen equipped with a teppanyaki grill and a 16ft fish tank.
Underground, there is a “wellness centre”, a hotel-style spa complete with a pool, jacuzzi and floating day beds.
Mr Palmer explains that the house is actually comprised of two properties, Sloane House and Sloane Lodge, where the couple would host guests for events.
Although stunning, the property hold some unhappy memories for Ms Ecclestone, who shared it with her ex husband James Stunt.
Ms Ecclestone married Mr Stunt in Italy in 2011 and the couple had three children together. They divorced in 2017.
