If you're curious to see inside one of London's most expensive houses, take a look at Channel 4's Britain's Most Expensive Houses, which takes us inside some remarkable homes across the UK, as many of the nation's wealthiest homeowners swap city life for the countryside.

The fly-on-the-wall documentary follows UK Sotheby’s International Realty and its wealthy clients. While all the properties shown were spectacular, the most memorable of all is this London mansion on the market for £40 million.

Located in North London's Highgate, home to the likes of Kate Moss, Liam Gallagher and Jude Law, Heathfield House boasts over 18,000 square feet and stands on 2.3 acres of land.

‘The real asset is in the land and the proximity to the [Highgate] village.’ Lee Koffman of UK Sotheby’s International Realty tells Homes & Gardens

‘It’s a great house for someone that works in town and wants some outside space and freedom.'

'You can go for a good jog around the grounds of this house, no one can look in, and you’re free from the worry of having to mix with people in parks.

'My client does have an alignment towards butterflies, so you’ll see butterflies throughout the house, incorporated within the design of certain elements,' Lee adds, explaining that in the spa leisure room, butterfly details can be seen in the tiles.
