After the death of Princess Diana the brothers shared her home with Harry going to live at adjacent Nottingham Cottage with Meghan Markle in more recent times.
However, the quaint cottage only has two bedrooms and two reception rooms and a bathroom and is not thought to be big enough for the couple once their new baby arrives.
According to The Sunday Times newspaper the brothers are preparing a plan to split the much larger Kensington Palace where William lives with Kate Middleton and their children.
A source revealed: “They are planning a formal division of their joint royal household, which is based at Kensington Palace, and the creation of separate courts to reflect their increasingly different responsibilities.
“The brothers have leant on each other and looked after each other since their mother died. But now they have their own families, they no longer rely on each other as before.”
The Duchess of Sussex is expected to give birth in Spring 2019 and it is expected that the renovations to Kensington Palace will take place at the start of 2019.
It is understood that both Prince William and Prince Harry are getting ready to live separate lives but still want their families to be close to one another.
Both Meghan and Kate Middleton will discuss the project with their royal husbands.
