For the past three years, Prince William and Princess Catherine have been raising their family in the charming yet modest Adelaide Cottage, a four-bedroom residence tucked away in Windsor. But now, as their children grow older, royal insiders suggest the couple may soon be making a significant move — potentially to a much larger and more historic property.

According to a report in the Mail on Sunday, the Prince and Princess of Wales feel they’ve outgrown Adelaide Cottage and are seeking a more spacious home that suits their evolving family needs. With Prince George, now 12, preparing for secondary school, the timing seems right for a fresh start in a new royal residence.

While several properties have previously been discussed — including Royal Lodge, currently occupied by Prince Andrew — a new frontrunner has emerged: Fort Belvedere.

This striking Gothic revival mansion, hidden within the secluded beauty of Windsor Great Park, is no ordinary estate. Fort Belvedere is steeped in royal history, most famously as the former home of King Edward VIII. It was there he shared his controversial romance with American divorcee Wallis Simpson, and where he ultimately signed the abdication papers that changed the course of the monarchy in 1936.

A move to such a storied and spacious home would be a significant milestone for the Wales family. The 59-acre estate offers far more privacy than their current residence, along with luxurious amenities such as a swimming pool and a private tennis court — features sure to appeal to the family’s active lifestyle, particularly Catherine and Princess Charlotte, both avid tennis fans.

So, is King Charles preparing to hand over the keys?

While Fort Belvedere is owned by the Crown Estate, any potential move by the Prince and Princess of Wales would require the King’s personal approval, making it far more than a simple real estate decision. The property is currently leased by the family of the late Canadian billionaire Galen Weston, but sources say that future arrangements could be made to accommodate the heir to the throne.

Though insiders stress that no move is imminent, the growing speculation around Fort Belvedere signals a new chapter for William, Catherine, and their children — one that reflects their increasing role in the monarchy and the practical needs of a modern royal family.

If the move goes ahead, it would not only mark a major upgrade in their living situation, but also serve as a powerful symbol of their central role in the future of the royal institution — and likely, it would have the full support of King Charles III.
