The cottage was built using parts from Royal Lodge, which is currently home to Prince Andrew and his ex-wife Sarah Ferguson.

As reported by Yahoo, "It's decorated with furnishings from the Royal Lodge as well as ornamental decoration from an old yacht—including some casual gilded dolphins."
The home is located in very close proximity to Royal Lodge as they are both set within the Queen's 655-acre Windsor estate.

Adelaide Cottage dates back to 1831 when it was built as a retreat for William IV's wife Queen Adelaide of Saxe-Meiningen, but it has quite recently been renovated so does not require too much attention ahead of the family's relocation.
We're sure once the family settle in, fans will get to see glimpses inside the beautiful home.
It is believed that the family will still retain Apartment 1A inside Kensington Palace as their London base as Prince William and Duchess Kate will frequently be in the city for work purposes.

The Duchess' parents Michael and Carole live in Berkshire which is also only a short drive away for visits.
