Their loft-style flat, designed by interior designer Eva Jiricna, is in the Royal Patriotic Building and includes its own turret.
This Victorian Gothic landmark, built in 1858 as a girls' orphanage, was used during the Second World War to interrogate Nazi prisoners, including Rudolf Hess.
Red carpet treatment for new box owner Harrods Estates has achieved a record sum for a five-seater box at the Royal Albert Hall.
Marketed at £250,000, it has just sold for 'in excess of £300,000' on an 863-year lease - the price of a two-bedroom Fulham flat.
Ownership enables the buyer and their guests to watch performances ranging from the current Cirque du Soleil show to the Proms, wrestling matches and pop concerts by Eric Clapton and Sting.
The red-carpeted box includes a rear area for cocktails and entertaining. About 1,200 of the hall's 5,500 seats are privately owned on a tenure similar to the debenture systems at Wimbledon and Twickenham.
