Hanover Lodge is a Grade II* listed house at 150 Park Road, London NW1, overlooking Regent's Park. It was designed by the architect John Nash, and built for General Sir Robert Arbuthnot. Since then, it has been home to several notable people, was part of Bedford College, and the residence of the French ambassador, before the businessman and Conservative peer Lord Bagri purchased a 150-year lease from the Crown Estate in 1994. The Russian billionaire Andrey Goncharenko purchased the outstanding lease from Lord Bagri in 2012 for £120 million.
Hanover Lodge was built in about 1827, and designed by the architect John Nash, "the only villa in the Park personally designed by Nash", for General Sir Robert Arbuthnot.
From 1832 to 1845, it was the home of Thomas Cochrane, 10th Earl of Dundonald, and the exterior bears a blue plaque in his honour. From 1848 to 1897, it was the property of the banker Matthew Uzielli (1806–1860) and his descendants.
The upper storey was totally rebuilt in about 1909, and the house extended, by the architect Edwin Lutyens. From 1911 to 1925, it was the home of David Beatty, 1st Earl Beatty, and the exterior bears a blue plaque in his honour. From 1926, it was the home of the American heiress and socialite Mrs von Hofmannsthal (nee Astor), daughter-in-law of the poet and librettist Hugo von Hofmannsthal. From 1948, it was part of Bedford College, but in the 1990s it was rented by the French government to house their ambassador.
