The house which will play host to Celebrity Fame Academy, is the second largest house in London, coming only after Buckingham Palace, the home of the Queen. The 12 hopefuls are living in this monstrous house named Witanhurst. The largest privately-owned house in London, Witanhurst boasts 94 rooms, including over 30 bedrooms! There is also a 70ft ballroom, a music room which has three grand pianos in, plus four tennis courts, of which two are grass and two are hard. The home which cost £35million to rent, also has five acres of land. Nov 03 03, 2:50 PM
