Luckily, Forest Lodge, the 328-year-old mansion in Windsor Great Park, looks an absolutely ideal spot for the family of five to begin again, with plenty of greenery surrounding it (something the Princess has routinely said is important to her) and more than enough room for the three royal children.

The Grade II-listed Georgian mansion will reportedly serve as their permanent home, even when William ascends to the throne – here's everything we know

Forest Lodge was last renovated in 2001 at a cost of £1.5 million ($A3.1 million) and went on the rental market for £15,000 ($A31,000) a month. At the time, the eight-bedroom property was valued at £5.5 million ($A11.4 million) but according to house price indices, the home would be worth about £16 million ($A32 million) if sold on the open market.

Prince William and family are moving to Forest Lodge on the Windsor estate, prompting uncertainty about the future of Buckingham Palace.

Kate Middleton and Prince William are moving their family to Forest Lodge, and their new home is set to be where they will live even when William becomes monarch upon King Charles' death.

Prince William and Kate Middleton’s move to Forest Lodge later this year - their reported “forever home“- is about putting the needs of their family first. Still, some royal critics are raising concerns about what this means for the future of the monarchy.
