So we know the royals like a bit of luxury, but two renovations in two years seems a little extravangant (even for homes obsessives like us)!
Last year Prince William and the Duchess of Cambridge spent more than £1.5 million modernising their Kensington Palace home - installing a new kitchen, redecorating the rooms and having an eco-friendly heating and hot water system fitted.
However recent reports have suggested that Kate is planning yet another programme of decoration.
The Duchess is understood to have become dissatisfied with the colour scheme she planned while pregnant.
To overhaul the apartment and plan her dream home, Kate has enlisted the help of architect and interior designer, Ben Pentreath.
Ben, who has an architectural practice and a shop in London's Bloomsbury, will have the task of turning their 20-room apartment in Kensington Palace into a family-friendly living space.
Having been a student at the Prince of Wales's Institute of Architecture and worked on Prince Charles's Poundbury model village in Dorset, the 42-year-old designer has plenty of experience.
Best known for his classical designs, he has worked on the fashionable Lime Wood hotel in Hampshire (where Sophie Dahl and Jamie Cullum hosted their wedding reception) and housing for Charles's Duchy of Cornwall estate.
He has also been drafted in to help at William and Kate's country home, Anmer Hall, on the Queen's Sandringham estate.
A Kensington Palace spokesman, said: 'the cost of any interior decorating and furnishing would be covered privately by the Royal Family'.
It may come as quite a surprise that Kate and Wills are able to splash so much cash on their London apartment as just last year it was revealed that the Queen needs nearly £50 million to repair her crumbling castles and below-par properties.
According to reports more than a third of the royal estate is riddled with asbestos and needs re-wiring. Buckingham Palace and Windsor Castle are thought to be the worst affected. The interiors of the Royal Palaces too are said to be cluttered and outdated.
So as Kate embarks upon her latest home renovation project, we hope she gets it right this time, after all, the plush pad has to house two future kings!
