McNair said the chateau was one of a handful built in the 1940s in memorium to the late capitalist Robert Stephen Moore, after whom the cul-de-sac was named.
Moore's wife, Florence, had the home and the cul-de-sac on which it sits developed as a tribute to her husband after he passed away.
It's also one of the only parcels of the original seven that hasn't been divvied up, meaning the large scope of the property is a rare find.
The home will likely find its new owner in a tech tycoon of the 21st century.
