Prince William and Kate Middleton are set to move into their "forever home" later this year with their three children, Prince George, Princess Charlotte, and Prince Louis.
Forest Lodge, an eight-bedroom mansion in Windsor Great Park, is undergoing renovations, which the Prince and Princess of Wales are funding privately to avoid extra costs to taxpayers.
The couple's decision to make Forest Lodge their primary residence, even after Prince William becomes King, has sparked debate about the future of Buckingham Palace.
Royal author Robert Hardman expressed concerns that Prince William residing permanently at Forest Lodge is "not tenable."
"I don't think that's tenable," Hardman said. "When the late Queen came to the throne in 1952, she and Prince Philip had just done up Clarence House as a sort of family home with their two young children. They loved it, and they didn't want to move."
Jacob Rees-Mogg echoed Hardman's sentiments, citing Winston Churchill's advice to Queen Elizabeth II in 1952.
"Churchill's advice was right, wasn't it, that the King needs to be the sovereign, needs to be in Buckingham Palace, needs to be present in that central place," Rees-Mogg said.
"Somebody, maybe Keir Starmer, I hope it's one of his long-distance successors, will have to give that advice in due course."
Prince William's approach to royal life is expected to be different from his predecessors. Last year, he mentioned trying to "do it differently" for his generation, suggesting a "smaller R in royal" would be his strategy.
Forest Lodge, with its relatively small size and secluded location, seems to fit this vision.
The situation can be compared to Spain's King Felipe VI, who resides in a modest home on the outskirts of Madrid, separate from the grand Royal Palace of Madrid.
Similarly, the Palace of Zarzuela serves as another residence and working office for King Felipe, much like Windsor Castle could serve as a counterpart for Prince William.
The mansion, valued at £16 million, features eight luxurious bedrooms, a grand ballroom, opulent marble fireplaces, and dazzling chandeliers.
With a tennis court on the grounds, it's perfectly tailored for Kate and their daughter Charlotte, both avid tennis enthusiasts.
The couple plans to retain other homes, including Kensington Palace and Anmer Hall in Norfolk.
