The Duke and Duchess of Cambridge's rumoured move to Windsor will see them swap the grand Kensington Palace for a "modest" four-bedroom home.
And this will reportedly mean the couple will not have a live-in nanny for the first time in children Prince George, Princess Charlotte and Prince Louis' lives. The Cambridge family are said to be upping sticks to move to Adelaide Cottage, which is nestled in the heart of the Queen's 655-acre Windsor estate and is extremely close to Windsor Castle. There are only four bedrooms in the cottage, one for the couple and one each for their three children.
And according to The Telegraph, this will represent a "significant change" as their nanny Maria Borrallo will no longer be able to live with them.
However, Ms Borrallo will reportedly be kept on full-time - although will live elsewhere alongside other staff that previously lived with the family including a housekeeper and a chef.
Ms Borallo was first hired by the Cambridges when Prince George was just eight months old.
She was often seen accompanying the children to the Round Pond at Kensington Palace - a stone's throw from her quarters. Her private living space includes a bedroom, kitchenette, lounge and bathroom.

She also has a private apartment at William and Kate's Norfolk country home of Anmer Hall.
The Spanish-born nanny attended the prestigious Norland College in Bath, which has been training nannies for the rich and famous since 1892.
Its curriculum includes sewing, cooking and nappy-changing, as well as skid-pan training and self-defence.
Meanwhile, not having a live-in nanny isn't the only change the Cambridge children will see on moving to Windsor - they are also rumoured to be moving schools.
The children are likely to be educated locally and are rumoured to be joining Lambrook School in Berkshire as day pupils.
The co-educational school charges up to £7,000 a term - plus a further £1,481 for boarding - and many of its leavers eventually head off to prestigious secondary schools including Eton.
It caters for both boys and girls, making it a more convenient option for the school run as both George, Charlotte and Louis can attend.
They will have to attend Saturday School which takes place each week, however, followed by an afternoon of sports fixtures for pupils in Year 5 and above.
William and Kate have reportedly been seen visiting the school "multiple times" - with William even chatting to one pupil about Latin classes.
Making the move from London to Windsor would be a huge step for the Cambridges.
But one royal insider told the Daily Mail that the relocation is due to William wanting to be closer to the Queen as she continues to delegate additional royal duties to him.
William is said to speak to his grandmother, who mostly spends all of her time at Windsor Castle, on the phone several times a week.
