British royals Prince William and Kate Middleton have some usual sleeping arrangements in their official London residence of Kensington Palace.
But it seems there is a simple explanation for the unconventional set-up in the 20 room 'apartment'.
The Duke and Duchess of Cambridge live in the palace with their children George, Charlotte and Louis.
However, new floor plans reportedly reveal that William and Kate go against the norm when it comes to the location of some of their bedrooms, the Mirror reports.
According to Hello!, it is reported that two of the master bedrooms in the palace are actually on the ground floor rather than the upper floors like most other people.
The royal residence is instead laid out in a different fashion to accommodate the staff quarters on the upper floors, the magazine reveals.
William and Kate have only shared small glimpses inside their home at Kensington Palace in the past, with their sleeping quarters strictly off-limits.
However, despite it being the Cambridge's home, Kensington Palace is also home to the Duke and Duchess of Gloucester, the Duke and Duchess of Kent and Prince and Princess Michael of Kent.
Meghan Markle and Prince Harry also used to live there, in Nottingham Cottage, before moving to Windsor, and then Canada and LA.
Parts of the palace are also open for the public to visit.
Speaking about the Cambridge family home on True Royalty's Royal Beat, royal author Christopher Warwick said: "It has 20 rooms from the basement to the attic, it is not a small house.
"All of these royal residences at Kensington Palace are called apartments, 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 Place 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."
