Inside The Apprentice’s incredible £17million mansion as the boys sink cocktails in the bar

THE Apprentice boys celebrated their debut challenge win with cocktails inside a £17million mansion on Britain’s most exclusive road.

Tonight, candidates got to grips with the sauna, hot tub and cinema room at the huge pile that they'll call home for the duration of the series.

The eight-bed, nine-bathroom luxury home is thought to be the most expensive pad used by the hit BBC show.

It is on The Bishops Avenue in Hampstead, North London — dubbed Billionaires’ Row.

The last time it was used by the show, agents estimated it cost the BBC £100,000 a month to rent.

Business wannabes including Joe Phillips and Marnie Swindells can also unwind in a fully-stocked bar after a grilling from Lord Sugar, as they bid for his £250,000 investment.

However, fired Emma Browne won't get to enjoy it after the girls were soundly beaten in the first challenge that saw the teams sell cultural tours in Antigua.

It also has a pool table, cinema room and gym.

Billionaires’ Row, which has 66 mansions, is home to some of the world’s richest people.

The Saudi royal family sold ten properties along the street for £73million, while the Sultan of Brunei is thought to own at least one house there.

Beatle Paul McCartney’s ex Heather Mills lived in an apartment in one of the houses.

It is not the first time Huxley House has appeared on TV.

It featured in Britain’s Most Expensive Houses on Channel 4 last year.
