Kensington Palace London - Arabstoday   The royal couple are set to make Kensington Palace their permanent residence starting in 2013, according to a spokesman for the Duke and Duchess. Currently making their temporary home in a two bedroom cottage on the Palace grounds, Will and Kate, both 29, will move into an apartment once occupied by the late Princess Margaret and remain there from mid- to late-2013. William\'s younger brother, Prince Harry, will move into their current home once the couple\'s new apartment, currently being used by the Historic Royal Palaces charity as office space, classrooms and storage, is renovated. The new royal digs are set to be designed by Kelly Hoppen, whose air fresheners and candles Kate favored when furnishing their temporary pad last summer.
