Mr Warwick, speaking to Royal Beat, explained how the residence is anything but a small apartment.
He 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.”

Mr Warwick went on to say the outside of the complex looks deceiving due to its design.
He added: “If you kind of think of them as being these wonderful red brick terrace houses.
“Because they are all joined, but separate houses.”
Royal author Ingrid Seward also said of Cambridge’s homes: “It’s enormous… and it’s like a piece of countryside in London.”

William and Kate live in apartment 1A, which is spread over four floors.
The Cambridge’s home takes up half of the Clock Tower wing of Kensington Palace, with five reception rooms.
Also included in 1A are three main bedrooms, each with ensuite bathrooms and his-and-hers dressing rooms.
There is also both a day and night nursery for Prince George, Prince Louis and Princess Charlotte.
William and Kate have recently began looking for a new housekeeper to assist at the residence, with the job hunt ending on November 7.
The advert reads: “This is an exciting opportunity to join a supportive and positive team. You will be a self-starter who also enjoys working collaboratively.
“You will be keen to take on new challenges as these arise and develop your own knowledge and skills.”
The Cambridge royals have also been tipped to leave the residence for while this month, as they are keen to get back to Anmer Hall in Norfolk.

In 2021, a new sculpture of Princess Diana, commissioned by William and Prince Harry, will be added to the Sunken Garden of Kensington Palace.
The royals said in a statement: “Our mother touched so many lives. We hope the statue will help all those who visit Kensington Palace to reflect on her life and her legacy.”
Kensington Palace also made headlines after Lucy Worsley, a BBC historian, announced she would be conducting a “review” into the building’s historical links to slavery.
She said of the inquest: “It is always great to push people a bit into an uncomfortable and darker direction, because then you can see the historical causes of things like social injustice.”
