Awakening a Jacobean sleeping beauty

The von Pfettens were well qualified to take on such a project. Jean Christophe, a French diplomat and professor, had bought back his family home, Le Château de Selore in Burgundy, in 2001, and impressively restored the historic house. Also seven- teenth century and with 108 rooms, it is not so different in scale to Apethorpe. Nadia was heavily involved in the restoration there and has also restored a family palazzo in Venice.

The von Pfettens will split their time between these three homes. Their daughter Charlotte is at school in England, and Jean Christophe's love of this country comes from the time he spent at the University of Oxford, along with his passion for hunt- ing. At present, the von Pfettens are camping in Apethorpe's old servants' wing, with one of the lodges used for guests. But it will be a long process bringing an abandoned Grade I-listed house, about the size of a Cambridge college, into habitable condition.

Some of the work is purely practical. They have just finished the demolition of many derelict concrete school buildings, which defaced the setting. Inside, an elaborate system of fire alarms has been fitted. 'It's one of the essential things in a house such as this, all very complicated, but not one which people will notice,' says Nadia, who is also planning the new plumbing. 'We are installing internal towers so no pipes run above important plasterwork.

'We like to take time - we treat an old building like a living thing and want to get to know it like a person,' she continues. 'We have a very simple philosophy: most rooms will be what they were designed to be, the dining room a dining room, the drawing room a drawing room, and so on,' adds Jean Christophe. 'We are making one change, however - turning a small panelled sitting room on the ground floor into a new family kitchen.' This looks out to the east and to the south. 'Nadia loves the south range, but I love the east front best. Jacobean architecture is the quintes- sence of the English character, rather lean and beautiful.'

They also have a poetic vision for the house: to bring it to life. 'We held our first concert last summer in the presence of HRH The Duke of Kent,' says Jean Christophe. 'I have had the chapel consecrated as an Anglican chapel as well, and this year inaugurated a Mass of St Hubert - a celebration of hunting and French horn music. In 2016, we also hosted the first lawn meet of the Fitzwilliam Hunt here for a century.'

These annual social events are as important to the von Pfettens as new plumbing and wiring, curtains and sofas and, they believe, will help revive the real spirit of this Jacobean house.
