Frogmore Cottage, which Prince Harry and Meghan Markle vacated, has been offered to Prince Andrew.
The Duke and Duchess of York have confirmed receiving an eviction notice for their UK residence.
Prince Andrew is said to be unhappy about leaving Royal Lodge for Queen Elizabeth II's five-bedroom residence.
Last year, the Prince and Princess of Wales and their three children visited Windsor from Kensington Palace.
The Duke and Duchess of Cambridge live in Adelaide Cottage, which has four bedrooms.
