Kate and William – alongside their children Prince George, Princess Charlotte and Prince Louis – will shortly make the move in the coming weeks.
It will be the first time they will live without a live-in nanny since 2014, when George was eight months old.
The move to Adelaide Cottage will be a significant change for George, nine, Charlotte, seven and four-year-old Louis.
Their nanny Maria Borrallo will still work full-time for the Cambridges – but live elsewhere.

Other support staff who have "lived-in" with the family at Kensington Palace, including a chef and housekeeper, will also live in separate accommodation.
The Duke and Duchess of Cambridge hired Ms Borrallo eight years ago – and she has been pictured with the family at official events ever since.
She sometimes travels with them on holiday and has her own apartment at the family’s Anmer Hall property on the Sandringham estate in Norfolk.
Adelaide Cottage, the new Cambridge residence, is a Grade II-listed property built in 1831 for Queen Adelaide – the wife of King William IV.
It places the family just a short drive from Kate's parents, Michael and Carole Middleton, and just a ten-minute walk from the Queen’s private apartments at Windsor Castle.
The couple hope the move will allow them to give their children the best and most “normal” childhood possible.
Group Captain Peter Townsend lived there from 1944 with his wife Rosemary and two sons.
It was at Adelaide Cottage that their marriage broke up and Townsend embarked on an affair with Princess Margaret.
Alathea Fitzalan Howard, a close friend of the Queen and Princess Margaret when they were children, wrote in her diaries in March 1941: “Daddy and I walked across the Home Park to tea at Adelaide Cottage, which the Queen (Mother) has lent Jackie and Joan Philipps for the duration of the war.
“I was charmed with it. It typically represents that idea of a little world within a world of its own, which is so characteristic of Windsor Castle and its surroundings.”
