Kensington Palace uses a subtle trick to prevent visitors from peering into Kate Middleton and Prince William’s private gardens when visiting their residence, a TikTok user has shown.

Parts of the palace, which contain the offices and London residences of the Duke and Duchess of Cambridge and their children, Prince George, Princess Charlotte and Prince Louis, are available to guests.

However, steps were taken to ensure the couple’s privacy, including partially frosted secret windows in an upstairs room to prevent the public from peering into their backyard.

Royal fan Laura-Ann Barr, from Northern Ireland, noticed the subtle trick during a tour of the gardens and shared footage of the ‘secret windows’ on her TIC Tac Account.

Sharing a comparison photo of the half-frosted window, she wrote: I’m on tour at Kensington Palace.

“Look at the secret windows they have to make sure you can’t see Kate & Will’s private garden to the right. They have it on every window in this room.

Despite being designated as their apartment, the couple’s private residence is said to be “huge” with more than 20 rooms.

Speaking on The Royal Rhythm of True RoyaltyBritish royal author Christopher Warwick said: “There are 20 rooms from the basement to the attic, it is not a small house.

“All of these royal residences in Kensington Palace are called apartments, which of course immediately makes people think of apartments as the American term for an apartment.

‘They are not. If you think of Kensington Place, it’s built around three courtyards. If you think of them as those wonderful red brick terraced houses. Because they are all together, but separate houses, ”he added.

Royal author Ingrid Seward also said: “It’s huge… and it’s like a piece of the countryside in London.”

Royal fans got a glimpse of the London home of the Duke and Duchess of Cambridge in 2016, when they entertained US President Barack Obama and First Lady Michelle in their living room.

The property has been refurbished with £ 4.5million in taxpayer money – though the couple footed the bill for fixtures and furnishings.

Kate, 39, had the help of an interior designer, but the look didn’t look particularly grand and far from a lavish, more comfortable country home.

Cream sofas were littered with flowery cushions, while a large hexagonal ottoman was added in the middle of their living room.

The Duke and Duchess of Cambridge’s apartment at Kensington Palace is “huge” with “20 bedrooms from basement to attic,” royal experts have claimed. Kate and William shared a glimpse of their separate home offices at the property earlier this year, seen above

In the corner was a grand piano covered in family photographs and flowers, indicating that it was more decorative than anything else.

The side tables were also filled with photos including a young Prince William with a tuft of blonde hair. The couple even had a drinks tray in the corner of the living room – which held £ 12 bottles of Smirnoff vodka and £ 14 of Gordon gin.

Apartment 1A is a spacious four storey property with its own large south-facing walled garden. It occupies half of the wing of the clock tower designed by Sir Christopher Wren for King William and Queen Mary.

The family of five has arguably the best apartment in Kensington Palace with 20 bedrooms and views over Hyde Park.

William and Kate moved into the palace in October 2013 after George was born, but the public rarely gets to see the interior.

However, photographs were taken when the couple hosted Barack and Michelle Obama in 2016 and we saw Prince George in a dressing gown meeting the former US President.

The Duke, first cousin of the Queen, and his wife live in the Old Stables, a historic cottage within the grounds of the palace.

The Gloucesters moved into the chalet last year after moving out of their old home in Apartment 1, where they were neighbors to the Cambridges.

Apartment 10: Prince and Princess Michael of Kent

Prince Michael of Kent, another cousin of the Queen, also lives in the main palace building with his wife, known as Princess Michael, in Apartment 10.

Apartment 10 has five bedrooms and five reception rooms, with one room formerly available for hire for £ 10,000 per month.

Wren House: The Duke and Duchess of Kent

Prince Michael’s older brother, the Duke of Kent, resides with his wife in the grounds of Kensington Palace at Wren House, named after architect Christopher Wren.

Although details have never been revealed about this house, it is roughly the same size as Nottingham and Ivy Cottages.
