At times during its life Cambridge House has been a Royal residence and was once the London home of Lord Palmerston the Victorian Prime Minister. It was also more recently the Navy and Military Club known as the ‘In and Out Club’.
The building is named after the 7th son of George III, who was entitled the Duke of Cambridge. It has also been known as Egremont House and Cholmondeley House.
The house was built between 1756 to 1761 to the designs of Matthew Brettingham in the parish of St. Geroge Hanover Square, for Charles Wyndham, 2nd Earl of Egremont. Following the occupancy of Charles Wyndham, the house changed hands a number of times and in the 1820’s it was the residence of George Cholmondeley, 1st Marquess of Cholmondeley and between 1829 and 1850 Prince Adolphus, Duke of Cambridge.
It was following the death of the Duke in 1850 that Lord Palmerston bought the House. Palmerston was Prime Minister for most of the period from 1855 to 1865.
Following Palmerston’s death Navy and Military Club purchased the house, and it became known as the ‘In and Out’. The ‘In and Out’ is one of the most exclusive gentleman’s clubs and moved out in 1999 to new premises also in Mayfair.
Today the Grade I listed building has been converted into the Cambridge House luxury hotel and Residences which includes a restaurant, wellness spa and pool, hotel bar, wine bar and function rooms. It was constructed in the late Palladian style and has three storeys in addition to a basement and attics and s seven bays.
