Kate Middleton and Prince William's main residence is Apartment 1A at Kensington Palace in London, but despite the name 'apartment', it's actually one of the most majestic royal homes of all. In fact, the home is so big it warrants its very own elevator.

Spread across four floors, it takes up half of the Clock Tower wing designed by Sir Christopher Wren for King William and Queen Mary, making a lift a useful feature inside.
There are a total of 20 rooms, including at least three main bedrooms, five reception rooms, multiple bathrooms, a nursery, his and hers dressing rooms, nine staff bedrooms, a home gym, a laundry room and even a luggage room.

Royal author Christopher Warwick put paid to the associations that come with the name 'apartment' on a recent episode of True Royalty's Royal Beat.
"All of these royal residences at Kensington Palace are called apartments," he explained. "Which of course makes people immediately think they are flats like the American term for an apartment. They are not. If you think of Kensington Palace, in a way, it is built around three courtyards. If you kind of think of them as being these wonderful red brick terrace houses. Because they are all joined but separate houses.
Royal expert Ingrid Seward concurred: "It's enormous… And it's like a piece of countryside in London."
Meghan Markle and Prince Harry's new home in Montecito, meanwhile, might appear more impressive on the surface, but it's actually much akin to the Duke and Duchess of Cambridge's abode, complete with private lift, albeit spanning just two floors.
Kate and William share their home with their three children Prince George, Princess Charlotte and Prince Louis, and also own a countryside retreat in Norfolk, Anmer Hall, where they isolated during the coronavirus pandemic.
