The designers proved that a historic building does not have to be the work of an era. When they moved in a few years ago, the couple's wife was a fashion and beauty executive and the husband was a New York financier from a prominent family. With the help of Jean-Louis Deniot, they modernized the four-story, 20-room historical treasure and turned it into a home for children to roam and entertain.

Jean-louis Deniot designs the entrance as a fusion of the Medieval Italian chair, the Reign of Louis XV of France, and the different ages. "We took down almost everything except the facade, which was marked. You can see the whole house from here, "Deniot said, looking out of the foyer. He took particular care to design a floor plan that highlighted the high ceilings and brought natural light into the centre of the building. The design darling is known for his skillful handling of historic buildings.
