Even England’s royalty can’t resist a good treehouse. Prince Charles recently renovated a portion of the Highgrove gardens into a royal woodland playground with a treehouse for his two-year-old grandson, Prince George. The new toddler wonderland is located in The Stumpery, a playground designed by William Bertram for the then five and three-year-old princes, William and Harry. The original design included a thatched roof treehouse, designed for William’s seventh birthday, which has now been relocated and passed down to Prince George.
