(CNN) -- In the final Art of Life of 2007 we explore rural residences and thriving country businesses in the UK.
The Art of Life team filming in Chatsworth House's stunning park
We look specifically at how many private homes and estates have had to adapt in order to survive the challenges of the 20th century. We go to Chatsworth House in Derbyshire where the Cavendish family has turned their home into profitable business. Next, we visit the foothills of Ben Nevis in Scotland to see one of Europe's finest hotels, Inverlochy Castle. In Ireland we meet the Leslie Clan who have managed to preserve their castle for over 300 years.
A quintessential English country house, Chatsworth's baroque architecture is thought to be the inspiration for Mr Darcy's Pemberly in Pride and Prejudice. The family seat of the Cavendish family for over 500 years, it has started paying for itself in the last 50 years. The 12th Duke of Devonshire, Peregrine Cavendish tells Art of Life about Chatsworth being a film location, and the other innovative ways the family makes the $9m it needs to keep the castle going each year.
One of only 30 family owned estates left in Ireland, Castle Leslie and its surrounding 1,000 acres is also home to one of the finest equestrian centers in the world. It is a far cry from the dilapidated ruin 6th generation Sammy Leslie took over in the 1990s. Today, the estate has an organic spa, cookery school, and private members club. We find out more about the transformation.
It was built in 1863 and Queen Victoria once paid a visit, but Inverlochy really came into its own when it was reopened as a country house hotel in 1963 - the first of its kind. It still feels very much like a home but with added comforts like the food for which the hotel has been awarded one Michelin star. We meet the staff behind this award-winning hotel.
